Re: 4l60e Problems and Solutions



The 4L60-E is an automatic shift, four-speed overdrive, longitudinally positioned transmission. It has been considered to be the best rendition of the finest overdrive automatic transmission ever produced. The 4L60-E is found in nearly every GM rear-wheel-drive application, including the C/K Truck, Sonoma, Jimmy, Tahoe, Yukon, Astro, Safari, Suburban, Bravada, Firebird, Camaro and Corvette

Before the Late 4L60-E transmission, there was the Turbo 700R, which was introduced in 1982.

I was driving last night and everything was perfectly fine. Went out this morning to drive and it wouldn't go into gear at all at first. It was cold too. About 15 degrees. It had been down into the single digits overnight. Any thoughts on what this could be? After it warmed up a bit, I could get it into gear but was having symptoms 2 and 6. Thanks for any ideas!
sounds like what my last trans, the one I just took out's problem. I had to let the fluid warm up before it would do anything.

No movement what so ever is blown pump. If you have a 13vane.. those are actually prone to exploding.

I might be able to tear the trans down soon.. When I do I will update with all the problems. The teardown can take some time, A LOT of parts.. but if you are looking to rebuild.. I will have my rebuild video done relatively soon.

Stick shift, full manual control, converts back to automatic. For transplant or use with no electrical, includes 46-MOD (vacuum controlled line pressure).
you would use this kit if you wanted to basically convert the 4L60E to a manual shifted trans that is vacuum pressure controlled NOT electrical.

So basically you are turning a 4L60E into a 700R4 transmission.. only making it have the ability to manually shift..

tell me you went this route and didn't install this thinking you could still use it as it had been before.. if someone sold you this as a "fix" they need to be drop kicked in the dink..

Re: 4l60e Problems and Solutions

slugger..

that bad o2 could mean the cat is bad.. you have to make sure of the code.. if it says o2 threshold is below.. blah blah blah.. it is more than likely your cat that is bad.. but after only 26k.. not sure..

as far as your trans is concerned.. sounds like it is doing what it does.. or should.

you want it to shift back and forth if it needs.. could you just be a bit paranoid in the shifting? I tell you what, I still have not totally tromped on my trans yet. I NOW have 501.3miles on it. I did however test it's mojo on the highway on ramp until those fun loving drivers going UNDER the speed limit stopped my testing

Get that other stuff fixed and get back to us.. hell post up if you need help with that stuff too.

Re: 4l60e Problems and Solutions

In 2001 the valve body gasket changed. There is a spot on the valve body that is different also. I will try to find a picture of that.


found this on the webbings..
Quote:
95 4l60e is a year all on its own with no direct interchange. you cant use the 93-94 because they did not use the pwm solenoid. 96 was the start of the removable bell housing and 6 bolt tail on the 4.3 models. 95 also uses 10-15 ohm shift solenoids VS 20-31 ohm 96 -up

Re: 4l60e Problems and Solutions

honestly, any of you guys wondering about the transmission should buy that dvd. It will tell you years, differences, all kinds of useful information.. common problems..

look on youtube for them also. You can see a portion of it from that alone.

That's easy. When towing, just put the shifter in "D" instead of "OD"

ugh, another component to replace. oh well, it comes with owning an older truck(1987 with roughly 240K kms/150K miles)

Question Re: 4l60e Problems and Solutions

Sorry but not sure how to post. I have a 2003 Chevy S-10, Automatic, 6 cylinder, 4.3 engine. I got the engine hot and bent a valve. I replaced the head gasket and valve. My truck ran great for a day but the next day, it wouldn't shift gears right (I had to take my foot off the gas pedal inorder to shift), it felt like it was accelerating on its own and not much power. Service engine code came up re: the crankshaft sensor so I replaced it, the heat sensor and pigtail and finally the distributor cap and I am still having problems. I thought maybe I needed to adjust the advance on the timing but still having the same problems. It feels like the overdrive is not kicking it. The rpm dial just skyrockets if I try to accelerate. Very frustrated. I drive 40 to get to work and don't want to damage the engine. Any advice would be greatly appreciated. Please Please help! I took the day off to look at the engine and try to figure it out. Thank you very much. Rick

Re: 4l60e Problems and Solutions

I have a 2000' 2.2 s10 automatic and it just started shifting itself out of drive down to 3rd gear after 60 miles or so. I can shut the key off and restart the truck and it's fine for another 60 miles or so. Any ideas...

Re: 4l60e Problems and Solutions

Hey guys 99 s10 2.2L Auto 110,XXX miles.
I had the trans rebuilt (2.5 years ago with 89,XXX miles on it- sunshell died)
Well, I no longer have a warranty and my truck is acting up again.
If I come to a complete stop and press the gas there is a delay before it starts moving. However if I let off the brake and let the truck roll for a second or two and ease into the throttle the problem is not there. This doesn't happen all the time like every other time I drive it. I checked the fluid and it looked and smelled fine.
Any advice is appreciated!

Also, been away from s10forum for awhile... nice to be back trolling the threads.

Re: 4l60e Problems and Solutions

i dont know if my issue is a transmission issue or what, but i think it worth giving a shot.

1995 S10 SS, 100.000 miles

Car runs if is not WOT.

Let me try to explain.

If you go WOT with the selector in OD, runs fine until 3500-4000rpm then fells slugish, fells like is losing power, and when if changes from 1st to 2nd, you can fell a kick, if driveway is wet you can fell it losing traction.

I dont know if i am being clear, but engine RPM goes up, but speed wont, but when it switches from 1st to 2nd, car really goes.

Re: 4l60e Problems and Solutions

transmissions are a beast.

You have to first get codes.

If no codes, check the wiring there will be some issues.

Once you get codes you can diagnose

If you don't get codes it is more than likely a computer issue. The computer issue is damn near always overlooked. Why is this?

I have been experiencing some gnarly shit on my trans, stuff that is not covered anywhere on any known troubleshooting guides or written about.

You have to basically immerse yourself into the transmission and its functions and how it relates to all other functions of the vehicle. Run down each one, trouble shoot each one so you can get it figured out so you can eliminate what the bad from good.

Then you can come back to the transmission. But not until then.

Transmissions are complicated, and that is why transmission shops are chalk full of business all the time..

with my last build, it, the build, went great aside from a sales guy who didn't know what the **** he was talking about and sold me the wrong converter.. and it overheated (went to shit) and that was what initially tore the trans up. The rest, an electrical issue on my truck tore the build up even further.. and I try to keep up on things, and try to make sure it is all good throughout.. it is in my best interest to keep it going correctly.

that said.. our transmissions are electrically controlled meaning that in the valvebody (trans brain) it depends on these sensors to do what it is the trans calls on them to do.

The valve body is metal on metal, bores and valves. In some instances the bores are worn, and you have to change to a valve with rubber or other (teflon and other) seals that help to keep the pressure where it needs to go.

These wear out.. you are looking at trouble. then it gets into the case (steels and clutches and the apply pistons).. they are pretty easy when it comes down to it, just making sure the tolerances are correct and you have it made.

Re: 4l60e Problems and Solutions

I thought I was having tranny probs. Ended up my throttle position sensor was bad. Causing erratic shifts that had symptoms similar to slipping. All better afrer a new TPS.

Re: 4l60e Problems and Solutions

My tranny seems to have developed problem starting more than a week ago.

I was getting on the interstate one day, and it just stopped shifting into 4th altogether.

I had the fluid flushed, filter replaced, and still had the same symptom. Then, about 4 days ago it stopped shifting into 1st on it's own. If I go to 1st manually it works, otherwise it takes off in 2nd from a stop (Also the 2-3 shift seems to be delayed). However, when it's cold it will take off in 1st for a few minutes.

I haven't heard any odd noises, nor have I felt it slip. No jerking when I put it in gear from Park, and reverse works fine.

I was curious if it might be a bad solenoid, but I've yet to see the dummy light turn on since this began.

Re: 4l60e Problems and Solutions

My 85 700R4 shifts into overdrive at around 35 mph and if I floor the throttle it wont downshift unless I manually shift it. Tv cable is adjusted properly and I am at a loss.

Re: 4l60e Problems and Solutions

Chubbin.. if you have a 700r you probably have problems with the seperator plate and the check balls at the least.. they wear like a mutha..

The 700r is a governor regulated trans. are you sure it is OD and not another gear and other gears are just not coming on?

check out that site I posted about the 30 top problems with the trans. I cannot for the life of me remember off hand what it was, but there is a particular reason this happens.. check it out.. you described it perfectly.

Thanks I will buy a kit and see if that helps. I'm positive it goes to overdrive because I can count the shifts but doesnt stay in drive long maybe 30 seconds. I also bought a tv replacement sleeve and plunger to try that. Hopefully the rack will be free soon so I can install all of this.

Re: 4l60e Problems and Solutions

Monitor the rpms, and what they should be. Mine was having a deal where it would get into OD, but the torque converter would never lock up. So teh rpms went down from D, but not as low as they should have been when teh TC locked up in OD.

This was the 4l60e

Thanks I think I have an aftermarket tach I can put in and check that. I appreciate the help. Hopefully I can check it out within a couple days

Re: 4l60e Problems and Solutions

I have a problem and I am hoping someone will get on and help me. I have looked at all the scenarios and everybody else's but mine is different. It sometimes is a little sluggish/slip from a dead stop, but not every time, occasionally revs a little and shifts firm into second but not every time, 3rd gear is fine, also my truck sputters a couple of times before going into overdrive but not every time. Check engine light came on, hooked it up and all it said was trans component slipping. It's a cheap device and I know someone who has a better code reader and see what it says. If anybody can help me out with what my problem is I would greatly appreciate it.

If the code is DTC P1870 then look at post #5 in the following link:
http://www.s10forum.com/forum/f13/4l60e-issues-510334/

There is an old TSB (10 years old) for this problem. Also, it is a common problem caused in general by wear of the solenoid bore(s) in the Control Valve Body.

TSB QUOTE: This wear occurs in the bore that contains the TCC isolator and regulator valves, and results in poor, or no, TCC apply.

Also, in the link above, there is reference to a MOTOR magazine article, which describes various aftermarket parts to 'solve' the bore wear problem.

And if not 'fixed' promptly, you will damage (destroy) your trans. Good luck.

When I turn my truck off and start it up again, the same problem happens again. What could this be?
Any luck figuring out what was going on? I am having the EXACT same problem. I back out of driveway, put it in D and take off in first, then as soon as I break and go to take off again it feels like I am towing 20 fat chicks. I then shift to N, shut the truck off / Restart and everything is ok for a minute until I stop again. I repeat the process and Im ok again. It seems as though after I drive for a while it kind of stops, but is happening more frequently.
What remedy did you come up with?

Re: 4l60e Problems and Solutions

I'm pretty sure this is common on all gm models but if your tcc valve is faulty, od will not engage and 4th gear won't work after warm up and/or after key cycling. As for towing fat chicks, replace your throttle position sensor.

Re: 4l60e Problems and Solutions

Sounds to me like your tranny is running fine. He's only kicking your ass because he's probably manually shifting through the gears.

Deeper pan and filter and Corvette servo will help keep it cool.
