Does anyone have a 4l60e kickin' around that they would let go for cheap? I had the Tahoe running real smooth, or so I thought, and I traded it for a 1987 Camaro Iroc Z. Anyways, the truck ran just fine for him for a little while and then he lost reverse and third gear with no warning. He took it pretty well, wasn't pissed, more sad because he loves the truck now. He doesn't have much cash to get it fixed at the moment. He's a real nice guy and I feel bad about the situation. I've offered to...

No longer required, thanks anyways. I found a replacement at Kenny's in Gatineau which appears to be a recent rebuild. I went there today and pulled the transmission for him. They come out real easy when the floor pan is removed! Thank God for sawzalls!

If anyone is interested, to remove the 4L60e....

Inspection plate bolts 10mmx4
Trans to engine block 14mmx9 for the main nuts and studs
Stud bracket nuts 13mmx4
Transfer case 15mmx6
Flex plate to converter 15mmx3
U-joint straps 10mmx8
Trans X-member mount 15mmx4


Short sockets 10/13/14/15mm
Long sockets 13 and 14mm
Box end wrench 15mm
Vise Grips help to start the bottom bolt on the 241 or 243 transfer cases, it's at a bad angle.
3/8" universal joint and a few different lengths of extensions 3" 6" and 12" we used.
Pry bar(not the flat ones)
Side cutters
Patience x100
Small sledge hammer and a block of wood will help "shape" the floor boards for the extra 1/2" of clearance(optional

1995 4L60e's were a transition year, don't use it unless it's going in a 1995
1996 to 1998 are direct bolt-in
2-piece Bell housing can be interchanged with one piece, provided they were mounted to a 4.3/5.0/5.7 and not the 4.8/5.3/6.0 etc...
Pre-1995 were OBD1 and before OBD1 they were not electronically controlled and were designated as the familiar 700R4

I believe this information to be correct, please understand that I am NOT an automotive mechanic(I am a refrigeration mechanic) and I am only providing this information in hopes that it may help someone. The tools are accurate, interchange should be used only as a starting point, always do your own research!

Mods: My original post can be deleted(I'm not sure how I can do that myself) The whole thread can be deleted if it is of no use.

Happy wrenching and Merry Christmas everyone!

NV231 transfer cases have a 5 bolt pattern, nv241/243 cases are 6 bolt. NV241 Manual shift - NV243 Electronic shift. Same case dimensions for the 241/243

Lol! Forgot to mention, this is for GM' vehicles! You can use a 2wd trans if you want to replace the output shaft, tailhousing, gaskets etc.... But at that point you might as well just rebuild the one you have.
