4L60E won't shift past 2nd	Justin	5-12-06
I have a 4L60E transmission in my 94 silverado 1/2 ton 2wd it's got 263,000 miles on it. It won't shift past 2nd gear it just revs up after 2nd. It never slipped or anything I realize it a lot of miles, but I don't have the money to buy a rebuilt one and not entirely sure if I need one. I was told it was a shift solenoid I bought a 3-4 solenoid from a dealership but there are two and I wasn't sure which one to replace I called a mechanic who after looking through a book told me the one on the drivers side. I replaced it and nothing happened. Anyone who has any ideas please let me know. Justin (jabe2000@hotmail.com)

ITS THE SPEED SENSOR! I SEEN TRANSMISSION CHANGED OVER THIS PROBLEM I DROVE AROUND THE BLOCK WITH NO SPEEDO AND GRABBED THE WIRES AND THEY BROKE IN TWO! GETS HOT BACK THERE! TWISTED THE WIRES TOGETHER AND IT QUIT! THIS IS THE #1 REASON FOR NOT GETTING PAST SECOND

I bought the same 94 Silverado truck with the same problem. I had the trans rebuilt by a Chevy mechanic. After installing the trans it shifted ok 3 or 4 times and went back to the same problem. I sent it back to the mechanic and he said I needed a new valve body. Same problem. Sent back third time SAME problem. Maybe I have an electrical issue with the wiring harness. I need help.

Re: 4L60E won't shift past 2nd	joe	3-3-08
My 97 4x4 Tahoe had transfer case problems, (jumping out of reverse),I failed to properly diagnose the problem and overhauled the transmission before I replaced the synchronizers on the transfer case. After 600 miles of excellent performance the 4l60e transmission is not shifting to hi gear. I have replaced the tcc valve and wire harness, installed a trans co kit, both solenoids. I went back in it and check all the clutches. However I did not replaced the torque converter. A transmission specialist is telling me the the torque converter is the problem. I don't understand why he is saying this because the stall rpm is occurring at the right torque. I have ordered a trouble-shooting book to help me with the problem. It not a money issue I am a senior and have mechanic all my life. I will be going back into it until I get the problem fix. Any help would be greatly appreciated.

I have had this problem come to me alot on high milege vehicles basicly i can tell you this, cruise control can help you greatly with this problem if you can go to second gear set the cruse control and the engine does not just keep increasing in rpm then it is more likely to be a solonoid but if it does increase then it is more likely to be that the 3-4 clutch pack is out of your trans.
Re: 4L60E won't shift past 2nd	Johnny	12-4-07
I have a 94 Chevy WT and it shifts hard and wont shift into overdrive. It just happened one day all of a sudden. Any ideas on what it may be?
Re: 4L60E won't shift past 2nd	yaqoob	3-22-07

Re: 4L60E won't shift past 2nd	lost pioneer	6-22-06
Your clutch plates are worn out
Re: 4L60E won't shift past 2nd	brandon	6-11-06
I have one with the exact same problem. So if you figure something out before I do please let me know. I will do the same if I figure it out. Thank you.
Re: 4L60E won't shift past 2nd	abe	7-22-06
Probably your 3-4 clutch pack burnt.Is the fluid smell burnt? could be sol. try switching the two around to see if it changes shift to being a no 1to2problem.
Re: 4L60E won't shift past 2nd	B	8-31-06
I had mine apart and nothing was wrong, the computer controlls the shifting with solenoids, something electronic I thing.
:4L60E has a slipping shift on all up shifts	dan	1-27-07
I have a 1996 chevy z71 with the 4l60e tranny. i just rebuilt the tranny and hve only put about 30 miles on it since. from the start it has not shifted firmly only while up shifting. it down shifts fine and once in gear, wether it be 1 2 3 or 4 or reverse it works fine, it just has that slipping feel right when it tries to shift. i think its the shift solenoids,but not sure since i did not replace them. any input would be greatly appriciated
Re: 4L60E won't shift past 2nd	hmmm mine too	11-20-08
My '97 chevy blazer just started doing the same thing, won't shift past second. 3-4 days prior, for no obvious reason, a fuse blew in my truck that controlled the inside lighting. Do you think all this maybe related?
Re: 4L60E won't shift past 2nd	Scott	3-25-08
My 93 chevy s10 with a 4l60e wont shift past 2nd. I got it to shift into 3rd once or twice so its there. other wise it just slips. The speedo works fine so i dont think its the sensor. the fluid is fine.
Re: 4L60E won't shift past 2nd	Fabiel	9-21-08
I lost first gear (intermitently) & 3rd after driving my '95 TransAm like a maniac one night. Before that event, the tranny worked perfectly, even under stress. I let the car cool down for a couple of days and got it out again. It worked fine for a couple of miles, until it got hot. The problem reappeard and, eventually, lost 1st gear for good. I researched and decided to start with the shift solenoids (1-2, 2-3) and oil/filter change. The problem persisted, but now I have intermitent appearances of first gear again. The guy who did the job says the old tranny oil wasn't so dirty for a 13 year old car and did not smell "too" burned. My next step would be learning more about the speed sensor thing. I have no problem with getting to the rebuilding/overhauling process to fix it "all", but I dread/fear this problem will persist even so. Please, keep discussing with whatever you can pitch in. thanks. Fab.

Re: 4L60E won't shift past 2nd	Jim Delp	10-8-08
My 1999 Yukon is also slipping. I tried driving in second in manual, about 30 mph, holding the rpm steady, and manually shifting into third. I could see the rpm drop slightly, that tells me it is shifting, but is slipping. Anyone know if thats a band adjustment or what that might be? Fluid level is right and not bright pink, but doesn't look burnt. Had the filter replaced and flushed at 55K, now has 101k miles. No warning light also. Thanks will keep in touch. Hope this helps someone.
Re: 4L60E won't shift past 2nd	GilKill	11-5-08
SAME BOAT. 94 GMC wont shift smooth after its hot. Its fine for the first five mins. but after it runs for a bit it, it wont shift. Whats kinda scary is it starts to make a funky sound and starts to smell.. I havent drove it since that hoping i saved the clutch plates.. Took it to aamco for a free est. and they quoted me 1600! They said it needed to be rebuilt. Im Gonna start with the wire harness from the dash to the tranny. If that dont work gonna replace silenoids and internal harness. And if that dont work whats the next step? Rebuild? Please Post. Gilkill..

Re: 4L60E won't shift past 2nd	Shawn	5-14-08

Re: 4L60E won't shift past 2nd	Lotus	8-12-08
Im havin the same problem with my 94 camaro wont shift from 2nd gear then it drops back to 1st anyone know this prob hit me up!!!
Re: 4L60E won't shift past 2nd	mike verdetto	5-19-08
I am a rebuilder for 35 yrs if you can't get past 2and gear it is usually the speed sensor or broken wires from the sensor. the sensor puts a signal from the sensor to a buffer behind the dash then to the computer to make it shift. the buffer can be bad too.4l60's 94 chevys were great for the buffer going bad
