Default V6 4L60E on a LS1?

So buying an LS1 fbody with a bad 4L60E. I see them for decent prices all over, some are LT1 4L60E's, some are 3.4 or 3.8L versions and of course then there are the LS1 versions. My question is, if I got any of the other 3 would they still work or should I just look for strictly a LS1 version? I would think only the bellhousing would matter if the connections are there.

So....

LT1 4L60E on LS1 - Will it work? Modification?
3.4L 4L60E on LS1 - Will it work? Modification?
3.8L 4L60E on LS1 - Will it work? Modification?


Thanks for any help!
Mike

LS1 has a removable 1 piece Bellhousing.
LT1s are different.

Not sure about the 3.4/3.8

Are they interchangeable and if so what modifications are needed?

no in shoirt all the trannys are different in one small way or another and its easier and cheaper to just buy one made for an ls. you can also use a 4l60e from a 99-up truck or van just as long as its a v8

I just answered a similar question in this new thread:
https://ls1tech.com/forums/automatic...fferences.html

It has a picture of the trans you want - a '98 or later with a bolt hole in the 12 o"clock position which indicates it has the LS compatible 300mm input shaft.

What is your budget? My buddy as a 4l60E with 40k miles on it. Works fine. It came out of a stock f body and he bought a built trans. PM me if you're interested.
