4l60e Problems and Solutions

brianstraker · 04-03-2009, 04:04 PM

Is there anything like this for 700r4??
Havin a bid issue i'm trying to figure out.

4.3sonoma26 · 04-04-2009, 12:00 AM

Hi, I have had my 96 Sonoma 4.3 for about a year now, and my tranny is acting a little weird I think. When I first start driving it shifts great with a nice punch from first to second, but after driving for a while, the performance deteriorates. It shifts through all gears, but the shifts get softer, and it feels like its just not pulling. It feels like you gotta give it more gas in order to make it move just as much. It is serviced regularly, but she just turned the big 100 thousand on me, and I am kinda wonderin what its starting to do. A rebuild kit is like 150, but I am wondering how difficult it is, and I would like to put a corvette servo in it if thats not too expensive. I would just like to know what you all think, and if a rebuild is difficult or even necessary.
Any feedback would be appreciated.

Thanks
Nick
Im also happy with my new cooper discoverer tires. I went from 205/75/r15 uniroyal tiger paws to my 235/70/r15 coopers. They are great and quiet.

I'm not exactly sure which mine fits under. I have a 97 S10 with 108,000 miles on it. When i got the truck a year ago it would shift hard into 2nd once and a while and then one day it quit. then a few days ago it started back. when you come to a stop and begin to accelerate it to about 3,000 rpms in first and then shifts into second. it feels like the transmission jumps into second. the other gears are fine with no problems, and it doesn't downshift hard from 3rd to 2nd, or from 2nd to 1st. i checked the fluid and it is fine. I would like to fix it cheaply if i can, and not have to have it rebuilt. please help.

i have a 96 pickup w/ a 4.3 and mine does the same thing except it downshifts fine. all fluid levels are fine and no leaks. it will drive normal for about 30 minutes of highway driving and then 1 to 2 shifts jerky but all others are fine. any ideas?

I had to pull it, I got a VERY nasty eMail from GM's legal department!

deMad10 · 04-29-2009, 09:34 PM

I think I have a good sign that my tranny is DONE but need to get a second opinion.

When I block one rear tire and spin the other the driveshaft will spin. Now this shouldn't happen if I have the transmission in park, correct? Am I missing something? It seems too obvious to be true...like there is some sort of electrical control. I have the pan off and didn't see too much in the way of metal shavings, but there is definitely something going on. It sounds like hell when I move the driveshaft back and forth when I am under it though...

1995 Sonoma 4x4 4.3 SLE 340,000 kms
Reverse grinds and jerks. Kinda feels like a brake drum is out of round. In neutral, it rolls smoothly backwards. All other gears seem fine. 4x4 seems to engage and disengage fine.

Suggestions?

Sportin'wood · 05-17-2009, 08:27 AM

99 4l60e behind a 2.2. Tranny would not shift except by manually moving the lever into each position. Truck pulled well in all gears without slipping so I took it to a shop to be scanned. Throttle position sensor (PO122 I think)was the stored code, but all it took was the scan to clear it and it works fine again. BTW, I did NOT have a check engine light.

PatrickJ · 05-24-2009, 10:29 PM

My '94 S10 4X4 shifts gears fine but hesitates for about 1.5 seconds when shifting from park into any gear.

There are no leaks and the fluid level is fine.

I'd like to have an idea of the cause before dumping any additives into it.

I appreciate any thoughts.

slow4.3 · 06-01-2009, 11:49 PM

24. Car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmision is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the underhood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.

i have a 95 4.3 with 152000 trans does everything like #24. my first question is what is tcc? and what is cel? and the fuse is good and all connections are good. im not good at wireing issues at all. could it be the shift soleniod.please help and this is my daily driver. is it safe to drive with only 2nd and 3rd?

deMad10 · 06-02-2009, 07:42 PM

I don't think anyone ever responds in this thread. All I ever see is people asking questions. You may be better off just starting a new thread???

i was wondering what particular fault it would be to make it into limp mode.

I got a 94 dime four banger aiuto tranny if I take off in od truck starts puttering have to drop it to first to take off faster then when I'm on the high way sounds like it's in a low gear any help is apriciated

93_Blaze · 08-27-2009, 07:19 PM

21. No movement in any gear: pump failure, or total loss of fluid. R&R, or refill pan and find the leak. If out of fluid, avoid running the engine until the trans is refilled to avoid pump damage. To check for pump failure, check fluid level with the engine off, then start the engine and recheck fluid level. If level does not go down when engine is running, the pump is broken.

Im a newb and this sounds like my prob but need a second opinion. My tranny is like if it was sort of in neutral in every gear (just revs up), BUT, it does has very little movement with the more i give it gas. I have to rev up high before it will move, and even then it is very little movement. What do you guys think? Same prob/solution as mentioned? Thanks.

can someone break it down for me please.

I think 97deluxeny and I might be having a similar problem. I drove our ‘96 4.3/auto Blazer (186,xxx mi) across the state and back this weekend. It drove over fine, and sat for the weekend. Sunday morning I pulled out of the driveway and it upshifted very hard, with an audible "thunk." I believe that was the 1-2 shift. After that under any kind of moderate acceleration (more than 1/2 throttle) it won’t upshift until the throttle is released, and then the upshift is very hard. I don’t think overdrive has gone away (didn’t seem to be running more RPM than before), but I discovered upon arriving home that reverse is gone.

Reading the responses I’m thinking that the TPS is shot, but I’d love more input from those wiser in the ways of the S-truck.

David Conwill · 09-04-2009, 05:35 PM

I stopped into the GM garage today, described my symptoms and was told it was a broken sunshell. Exactly what additional harm might I cause if I drive it some distance to have it repaired? Or is this something a shade-tree mechanic can tackle?

-Dave

pbeguy · 10-06-2009, 09:49 AM

I swapped a known good 1999 4.3 and 4L60e into my 1998 2wd Blazer.
Had to put old harness on to get engine to start. Engine runs perfect.
Needed 9 qts ATF to fill. In D it feels like it slips badly. R is great. In 1 it seems great. No 2 at all. 3 is good when manually shifted. Even in D it stays in 3.

Codes a 756? 1-2 not working.

Dropped pan, checked all connections. Put in a B&M kit and set up for street.

When I checked out before install, Trans fluid looked very good (33K)
Sat up 3 yrs in shop.

Where do I start?

JohnnyDigits · 10-06-2009, 10:34 AM

27. Shift suddenly become very hard. When going from park to either reverse or drive it slams into gear. 1-2 and 2-3 shifts are also harsh. All gears seems to work. Problem may be intermittent: Check TPS for smooth electrical response. If the response is jumpy or erratic at all, replace TPS.

This has been my problem for like 2 years and I could never figure it out and frankly just dealt with it. I'm going today to buy a TPS and see if it'll solve my problem. I've been driving around for so long now like this that it's become "normal" operation. Hell I should've found this thread along time ago.

JohnnyDigits · 10-07-2009, 09:34 AM

So i replaced the TPS last night. Yup that fixed my problem. Now I'm shifting smooth as a baby butt.

One note to add for the simple install. When you are replacing the TPS it's on the passenger side of the throttle body. Removal is 2 torx bits and a plug. Very simple. Re-installment may or may not be a little tricky. The little screws are easy to drop on top of the engine, and when you put the new TPS on, put it on with the bolt holes not directly lined up but rather to the left and then turn the TPS clockwise until the holes line up. Return the 2 screws and put the plug back in. This took me all of 15 minutes to do only cause I kept dropping those little bitty screws.

dstappity · 10-17-2009, 08:11 PM

how about this one....i have a 2004 4l60 (ls1 swapped sonoma) and i have no 1st and i have no overdrive. when i first started driving the truck it did this for a couple weeks, then i decided to take it up to the local streetracer hangout about 19 miles from my house. i was driving home later that night and about 100 feet from my driveway it decides its gonna shift into overdrive and i havent had a problem since then.

now heres the kicker, last night i went up to the hangout again truck did fine all the way up there but when i left i decided to do a little spin out (raining) and when i let off, low and behold there it was not shifting into 1 and od again..what the heck

any help would be appreciated.
(i know it sounds like electrical issue but, i dont know where to look and i hate wiring)

edit:
oh yeah, along with the tranny problem also my abs is going crazy(and i have abs light on)and brake light is on

Sumits8 · 10-28-2009, 11:24 PM

My cars harmonic balancer had justworn out.. and when it went my car wouldnt hit drive or 1,2,3 and OD but it still went on reverse. i was wondering wat might be causing this.. and wat would be the cheapest way to fix it

dcoogan · 11-07-2009, 12:59 AM

No shift out of 1st , Reverse is perfect and so is 1st just no upshift

Marmle · 11-15-2009, 04:31 AM

Mine has a delayed shift from park to 1st then hits hard... then also 4th gear slips.. any one know what years would fit in a 99 2.2 RWD.

Telemarshallman · 11-16-2009, 05:09 PM

ok, I'm a brand new member here after a long time membership to mys10.com. I also know almost nothing about automatic transmissions. I've got a 94 (1st gen) 4x4 blazer with trans issues, but thats for later.

At the moment:

I'm helping out my best friend.

2000 Chevy Silverado 1500 4door longbed 4x4 5.3L 4L60E.

We were driving around in the truck we he said "Listen to this whine" that sounded like something in the air intake track. RPM dependent, barely audible, but there when you listen for it, intermittent.

about 10min later the gear indicator (box that highlights R N D etc) went nuts. It was jumping from D to 2 then to R and at one point it disappeared. Immediately following was massive slippage in 1st then nothing. It was as if it was in neutral.

We stopped and checked the fluids and looked for leaks. Finding none we started it and it was fine for a quarter mile or so then the same problem.

After checking the codes (knock sensor and TPS) is still will run fine for a quarter mile then no gear or motion.

I'm thinking it's a pump failure after reading this post, but I don't understand why the gear indicator is freaking out. I plan to check the level with the engine running and then turned off.

Any advice or wisdom?

Drjeffro · 11-17-2009, 08:31 PM

My tranny needs rebuilt. I have not been able to figure what the problem is, but I think that I have driven it enough since it started screwing up about a month and a half ago, that too much damage has been done save it. When I get the rebuild done, I want to put in a shift kit, nothing crazy, just firmer shifts and stuff. I have read on here about the Transgo kits, but I don't know what to get. Can anyone point me in the right direction for a complete shift kit?

I'm going today to buy a TPS and see if it'll solve my problem. I've been driving around for so long now like this that it's become "normal" operation. Hell I should've found this thread along time ago.

Now I'm shifting smooth as a baby butt. One note to add for the simple install. When you are replacing the TPS it's on the passenger side of the throttle body. Removal is 2 torx bits and a plug. Very simple. Re-installment may or may not be a little tricky. The little screws are easy to drop on top of the engine, and when you put the new TPS on, put it on with the bolt holes not directly lined up but rather to the left and then turn the TPS clockwise until the holes line up. Return the 2 screws and put the plug back in. This took me all of 15 minutes to do only cause I kept dropping those little bitty screws.

(i know it sounds like electrical issue but, i dont know where to look and i hate wiring) edit: oh yeah, along with the tranny problem also my abs is going crazy(and i have abs light on)and brake light is on Last edited by dstappity : 10-17-2009 at 08:18 PM.

I also know almost nothing about automatic transmissions. I've got a 94 (1st gen) 4x4 blazer with trans issues, but thats for later. At the moment: I'm helping out my best friend. 2000 Chevy Silverado 1500 4door longbed 4x4 5.3L 4L60E. We were driving around in the truck we he said "Listen to this whine" that sounded like something in the air intake track. RPM dependent, barely audible, but there when you listen for it, intermittent. about 10min later the gear indicator (box that highlights R N D etc) went nuts. It was jumping from D to 2 then to R and at one point it disappeared. Immediately following was massive slippage in 1st then nothing. It was as if it was in neutral. We stopped and checked the fluids and looked for leaks. Finding none we started it and it was fine for a quarter mile or so then the same problem. After checking the codes (knock sensor and TPS) is still will run fine for a quarter mile then no gear or motion. I'm thinking it's a pump failure after reading this post, but I don't understand why the gear indicator is freaking out. I plan to check the level with the engine running and then turned off. Any advice or wisdom?

Drjeffro Registered User Join Date: Mar 2006 Posts: 46 Location: User is: OffLine	Re: 4l60e Problems and Solutions My tranny needs rebuilt. I have not been able to figure what the problem is, but I think that I have driven it enough since it started screwing up about a month and a half ago, that too much damage has been done save it. When I get the rebuild done, I want to put in a shift kit, nothing crazy, just firmer shifts and stuff. I have read on here about the Transgo kits, but I don't know what to get. Can anyone point me in the right direction for a complete shift kit?
