How screwed is it? or paging Dr. Gatekeeper - Trans Woes

Postby Slick470 » Mon Aug 18, 2014 9:44 am

Ok... so I have a 2002 Chevy S-10 ZR2. Great truck has given me 10 years of great service and 2 years of fixing minor stuff that is expected with a now 12 year old vehicle. It is low mileage a bit over 70k.

So, In the past couple of years I've put new tires on it, replaced the radiator and in the past three months or so I've replaced the water pump and starter. Due to these past couple parts, I haven't driven it that much. While chasing the starter issue, I noticed that I was leaking a bit of ATF. Not much, but I've been keeping an eye on it. When I do drive the truck I'll check the levels after things have warmed up some and the levels have been ok. Since I haven't been driving the truck much, it's been acting a bit "stiff" until it warms up. Slow off the line, hesitating, feels like the brakes are dragging some, the like. Once it warms up things seem fine. I'm probably due for new vacuum hoses, as they are starting to get brittle, so I've chalked that up as part of problem.

So, Saturday, I drove the truck to the boat. On the way, it drove fine, no issues. In fact, it drove better than it has in a while. On the way back, I made it about 15 miles from the boat at about 60 mph and then when changing roads to go up to 65-70 mph 3rd gear dropped out. I pulled over and checked levels and the transmission dipstick was dry. I limped it two blocks to a gas station and bought a couple of quarts of ATF and added fluid about a half quart at a time while driving in 2nd between fills. Truck was happy in 2nd so I drove it home that way and keeping my rpm in the 3k range.

So I found this website. http://www.twincharlotte.com/transmission-repair-blog/bid/28391/30-Common-4L60E-Transmission-Problems-Repair-Charlotte-NC and I obviously have problem #6, but I think it was caused by low fluid. I can see where I had a bit of #1, and #12 sounds like my previous issue that felt like my brakes dragging.

So far, the truck doesn't have any codes or odd noises. Fluid "looks" fine, but it's hard to say what the fluid that was left looked like prior to me adding more.

I was thinking about pulling off the skid plates and looking for the source of the leak and seeing if I can tighten things up. It had a fluid, filter, flush around 60K, so there is a chance that something just worked loose. Then topping things off to see how it goes.

I have a line on a transmission shop that a co-worker recommends, but I'm trying to figure out where I stand. Rebuilding doesn't seem too hard, but I have a time issue. Swapping out for an R&R sounds like a decent option too, but I'm not quite sure I'm there yet.

Thoughts? Thanks!

Rebuilding an electronic auto transmission "isn't too hard"?

You should be giving advice, not asking for it. ;)

I've had a couple of 4T60E trannies (same but sideways) and the only problems I've had were the lockup converter solenoid dying - just disconnected it and lived with 200 RPM more on the highway - and leaks after getting them serviced. I always watch them very carefully after a flush & fill because they must torque the pan with air wrenches in those shops. If you ran it off the dipstick I think you're in for a full rebuild unless you get REALLY lucky - heat is the one thing an auto trans won't tolerate.

For the record, I put nearly 1/4 million miles on the first before it needed a rebuild and I have 100K on the current one with no problems. I used to put synthetic fluid in them but an old trannie guy said Dexron is actually better.

doesn't seem too hard is probably a bit optimistic, maybe sounds like a fun challenge... just the tearing it down and rebuilding part with a proper shop manual... it's the troubleshooting and making sure that the parts are in good shape prior to putting it all together that is more of the part I don't understand. Since I don't have the time or place to do this right now. It's really a moot point.

I don't understand why I could go from ok on the dipstick to at least 2 quarts low without a major blowout. Another thing I just read is to check the transfer case. Sometimes the seal between them starts to go and fills up the transfer case side of things. Hmmm...

Do you have a clean room to do the re-build? Modern slushies are very sensitive to contamination. In my experience you need a room that is much cleaner that what is required for an engine build or work on a manual transmission.

nope, not at the moment at least. My shop space is still in flux while I finish sorting out the home renovation. I really don't have time for that level of a project right now. I think it would be fun, but I'm probably limited to pulling the old one and putting in a rebuilt one as far as my level of effort is concerned for now. Even so, I'll probably have a shop do it all.

For the future, there are apparently all kinds of upgrade rebuild kits that can be had to improve these. Not sure that it is really necessary for how I use the truck, but it would a fun learning experience.

For now though, I'm trying to get a handle on how badly I've screwed this thing up. My gut feeling is the same as SloopJonB's that I've probably toasted it unless I got really lucky.

The truck isn't a daily driver anymore so I have some time to research things.

You need to be clean when you assemble them but not like doing turbos or microchips. Similar to engine building. Pulling a garbage bag over it when you leave it is good. Checking the parts is mostly straightforward - looking for scoring, chipped gear teeth etc. The place where experience counts is the clutch packs - a good eye can tell if they can be reused but why bother - just replace them. Since you won't likely have a trans adaptor for an engine stand, hanging the case in an oil drum will make assembly easier - you load everything but the valve body from the bellhousing.

If you are doing a rebuild, get a shift improver kit at least - you can choose how quick/hard you want it to shift, reset the shift RPM points and so forth. Quicker is better for longevity but less comfortable - you can choose to make them virtually instantaneous but they really snap your neck then.

Full disclosure, I've never turned the wrenches on one, only passed tools and parts and asked lots of questions (and paid the bills).

No, I don't mean chip fab clean, but cleaner than an engine re-build. We do engine assembly in a semi-clean room. In my experience turbos don't need it especially clean - much less than an engine re-build. Manual trannies and turbo work we do out in the open. But, if you go to a good specialist automatic transmission shop, you'll notice how clean they are. DIY slushie builds get a lot of mysterious failures and I think some of that is due to build hygiene. Dunno how that experience crosses over from AWD Subie slushies to other cars. For me it's a 5k USD part with a 3 week wait, so I'm very careful.

OK...I missed this thread but I'm here now. Working inside an automatic unit is NOT a DIY project. This unit has likely lost the 3/4 clutches due to the leak and will have to cleaned properly and repaired. Don't pass on the torque convertor, a world of crap can reside in there and there's no way to properly clean it.

Get a recommendation for a good shop and get it done right. The ability of a DIY to even know what is reusable and what is not is suspect. The updates are critical to ensure long term success, ask the shop tech about Sonnax valve body parts.

Suspect the cooler lines on the unit...GM used shitty material and ruined a lot of units because of it.

On the good side, GM made it possible for me to pay for my son to get a good education :lol:

Thanks Gate, that's good advice. I now have two recommendations from co-workers who have been happy with local transmission shops, so I'll probably call around in the next couple weeks and see where that goes.

I haven't driven it since I got home but checked the fluid over lunch yesterday and it is no longer red, but sort of a brownish red color.

Is there a chance that now that the unit has cooled off that the 3/4 clutches may come back now that it has cooled down? Is it worth even checking? If by complete chance they are back, what then? Do a filter, flush, and fluid or opt for a re-build anyway?

Also, any thoughts on why the levels would show ok for so long? After I lost 3rd gear, I crawled under there and there wasn't a large amount of fluid under and all over the underside truck, so I don't think it was sudden. It also seems to be keeping what I put in it.

Brown fluid is burnt and likely smells like toast (appropriately enough) - the old saying was it should be "pink with no stink". A flush & fill would be cheap enough to try before deciding it it's dead, except for the flush part requiring a special pump to drain out the torque converter. That would require a tow to a properly equipped shop so the cost will start getting up there unless you can get it moved for free or very cheap.

Before making any decisions though, you should trace the leak - chances are it's simply a badly torqued pan - I've had that happen more than once after a flush & fill at a trans shop.

Slick...don't waste your time and money doing a service. No amount of maintenance will put material back on clutches, soften burnt seals, or heal damaged metal parts. All trying to service this now will do is throw good money in the trash.

As too the leak, once that's determined it will all make sense. Some leaks are small and high pressure so the oil mists off and is hardly noticed. Some push ATF into the rad so check the AF just in case, if it looks like a strawberry milkshake you have your answer. Slow leaks are the most damaging because they allow a unit that is starved for oil to keep working, and hurting itself. Often the unit works poorly until warm, then the fluid expands until there is barely enough to develop proper pressure...until you round a corner, climb a steep grade, brake or accelerate.

The 4L60E is a piece of crap build with lousy quality material. GM ignored simple problems for years with this unit and hung the owners out to dry...in the hands of a good tech it can be made into a solid unit but the upgrades, many of them minor, have to be done.

(As an aside I owned/ran one of the top transmission shops in Canada's largest chains for 25 years. Sloop knows who we are :D We (my store) won numerous awards and had a very high customer satisfaction rating. Not bragging, just trying to establish some credibility. There is no scenario you can give me I haven't seen a hundred times or more)

Spend your money, don't waste it...I'm sure you work hard for it. Any shop that offers a service as an alternative is only interested in your money. Leave promptly.

p.s. if the pan is dropped it may be clean...the filter has a pocket and all the debris may end up in there. Any good shop will break it open to see what is lurking there.

Dexron is a trade name that GM uses to extort a royalty from every litre sold...Ford used Mercon to do the same thing.

If a unit is designed to accept synthetic, then it is the best choice. A 2002 can take either with no issues. Older units should stick with regular ATF.

Gee.. Hopefully my advice came across as don't DIY, but reading what I said it might not be so clear. The success rate I've seen with slushies worked on outside of a specialist shop is like one out of three. Due to low tech skills, even the dealers out here will just replace units or send them to specialist shops. I "have" :D to crack open the front third of my tranny to change the front diff from 3.08 to 3.52, and I will be using a specialist shop. Its a simple job, but no one outside of them has the right environment.

Thanks everyone for the advice. I posted this here, because I knew that Gate was in the business and I don't have to filter out half the responses to get to the useful stuff like other forums.

I'm completely pissed at myself for missing the warning signs on this transmission and costing myself a decent amount of money to fix it. I've never had transmission issues before so I'm pretty new to this, but that's not a good excuse. I obviously haven't been as up on maintenance for this truck as I should be.

The thought of DIY intrigues me. I like to see how things work and take a bit of pride in being able to fix things myself. I've rebuilt engines in the past but have always thought of transmissions as something beyond my skills. I've read quite a bit on the S-10 forums and the ZR2 forums about the different failure points and repairs for these trucks. (isn't it wild that there is a forum for pretty much anything these days?) There are step by step threads and videos on the teardown, parts replacement, and rebuilds for these transmissions and lists of parts that are recommended to update and where to buy. I take a lot of this with caution, as most of these guys are spending time upgrading everything about their truck, have a garage, and are generally beating the hell out of the truck on the weekends. Mine is basically stock, I don't have a garage (so I work around sunny days, but I have a 16x12 shop space in my basement for stuff once it's off the truck) and I use the truck to haul lumber, mulch, manure (for the garden), boat stuff, and getting places when the weather is nasty.

The fact is, I just don't have time in my life right now to even try this myself, so a shop will see this transmission. After that I will follow their recs to stay in compliance with whatever warranty comes with their work.

Slick,

I've heard good things about a Jasper rebuilt transmission. Comes with a good warranty and my local mechanic swears by them. Says on the rare occasion he has a problem with one, they step up on the warranty without delay, including his labor. I never got to use the warranty because the vehicle was crushed by a tree during Irene the day I picked it up.

Don't feel bad Slick, you are a long way from being the first!!

As far as DIY I'll put it this way...I was not a tech, but I did much of the technical research for my two builders. I would tackle a DIY on an engine any day, but not a transmission. When I watched my top guys build, they "saw" the parts as much with their fingers as their eyes. What their eyes said was a perfectly good bearing or bushing, their hands knew better...the ability to know good from bad is the hardest thing to teach a transmission tech.

Don't even try it Slick...pay a good shop. I have seen $650 worth of new parts get wiped out in the first 30 seconds because a tech missed the fact that a valve body spring was weak or too short (pressure regulator) or an EPC solenoid that tested well cold, worked out of spec hot.

As to Jasper...I have ever only seen a couple of them, but they looked to be well done with good parts. Not as good as my guys did, but in the hunt.

This was my shop...any transmission shop worth dealing with should look this clean.

Hmm... Jasper is the most expensive of the rebuilds that I've come across that aren't performance upgrades. I do like that when you use their pricing tool they come up with a list of the upgrades that they do to the stock transmission, all for reliability. I'm guessing that installed, they would be in the $2500+ range. They also don't list an automatic as available for my truck, so I put it in as the standard 4x4.

OK...that price seems a bit extreme...when you said "standard" did you mean as in a standard 4x4 vehicle package, or a standard transmission?? A standard transmission is far more expensive to replace than an automatic.

You are correct you don't want performance upgrades, just durability upgrades.

Standard as in an S-10 LS 4x4 instead of the ZR2 offroad package. As far as I know the only differences are trim level and suspension upgrades and the engine and transmission are the same. For whatever reason when I go through the drop down options for my truck, chevrolet, S-10, ZR2, 4.3L, it doesn't give me automatic as an option. If I put in LS, or just 4x4, I get the proper transmission.

Their pricing breaks out as $1999.00. They add a refundable core charge and a skid charge and a cost for a transmission cooler kit for an additional $254.00.

They seem to have a 3 year/100,000 mile warranty for parts and labor. So that is built in the price.

I would assume that installed I'd be over $2500 at those prices.

Interesting that they don't list an automatic. I just went in and put in a ZR5 instead of the ZR2 and it kicked out the 4T60-E as the stock PN for 1999 plus core and a cooler. I went with Jasper because that is what my very trusted mechanic sells and I didn't have time to do any of it myself. I'm sure there area shops that do as well and you have more options then us poor country folks. The car was in otherwise great condition and I expected it to get me through my kids college years. Irene and Mr 120' oak had a different plan.

I wish I could have done it for 2,500 but the Lexus was a lot closer to 5.5K installed. Because of the packaging and access, I had a lot of install labor. Pickups are usually a lot easier to work on.

I hear you Larry. Retail on this truck in good condition is about $9000 and trade in is about $6000, so at a certain point, the economics don't make much sense.

I have heard, but not confirmed, that a typical rebuild should cost me in the $1600-$2000 range depending on how many bits need replacing. An extra $500 isn't out of the realm of possibilities, but I'm a thrifty guy. Or I at least try to be.

I also don't really have a trusted mechanic. I have a couple of shops that I've been to where I don't feel like I've been screwed over... and others that... well not as much.

I hear ya on the mechanics. I used to do all my own work. It's how I had an MG in high school. When I got down here, I travelled a lot and Lynne ran into a couple of car problems while I was away and I ran into a couple of the "other kind" of mechanics. I found this guy and he is great. Long time southern MD family, lions club, chamber of commerce, etc. Not the cheapest but has proven himself time and again. I trust him to the point that If he tells Lynne something can't wait, I know he won't be afraid to look me in the eye when I return. I don't shop his prices and take the cars there for routine servicing and he returns the loyalty. It's. Ice to have that kind of local mechanic.

I haven't done anything with the S-10 other than took it for a spin around the neighborhood and no, the 3rd gear did not magically come back, but now I have another question.

I'm probably a bit over sensitive to this due to the S-10 but I also own a 2007 Ford Explorer with the 4.0L V6. I haven't had it that long and the PO took it to the local Ford dealership before I bought it and had it serviced. They did the usual multi point inspection thing and checked for leaks the fluid levels and conditions and the like. All came back good.

So, occasionally it shifts hard, and/or delayed. It isn't consistent and usually happens when I'm in stop and go traffic. If I'm on the pedal, it's pretty smooth. Is this something I should have checked out or somewhat normal? Again, I'm sort of new to this vehicle and it drives a bit different than anything else that I have owned like it.

ugh.... well the quotes are in for the rebuild. Looks like several local shops are all within a few $100 of each other at around $2700. Ouch.

Ouch! That's a lot of money. Can't you get a new one for the same price?



At risk of going OT, I'd love to ask questions about TCMs, shift line pressure and running more torque through a slushie safely.

I've got 350 lbft peak torque running through a 5EAT that was 214 lbft stock and I want to get it to 400 or more. I have a whole bunch of untapped mid-range torque untapped due to fears about the transmission.

I priced out some "new" ones through GM and they are around $1900, + install, so probably not much difference in the end. The rebuilt one will have a heavier duty torque converter, clutch plates, and apparently Corvette servos. There are also some other bits that they are replacing that are better than stock to improve longevity. So, part of that cost is in better parts. They said that they do all of their 4L60E rebuilds the same way unless the customer is looking for something specific.

The shop has been straightforward with me so far. Which has been nice. Pricey, but nice.
