The typical response I'm getting is that I can't make my current transmission bolt up to an LT1. Which drives me CRAZY. I spent $1750 on a build for this transmission and it's strong enough to take the torture from a V8...

I think people just automatically assume they can't be interchanged. But it just doesn't make any sense to me. They're both 4L60Es, just the bolt pattern doesn't fit.

So could someone who knows for sure please chime in, thanks

 

You have to get a V8 bell housing and take yours off and swap it with the V8 one... should be the only difference

Most people when doing V6-->V8 swaps just skip the trouble and get a new tranny/engine combo..

 

Ok unfortunatly if the info in your sig is correct They are correct the 95 3.8 trans did not have a removabale bell .So the bolt pattern and bell size are completely wrong. In order to make that work you would have to swap the guts to a V8 case. Next in addition to that the input shaft is wrong, So you would need to change that too.
To Sum it up,
1-change to a V8 case by swaping internals
2-change the input shaft

Once you have done these things you will then be able to put your trans in a V8 application

 

Well I learn something new every day... I don't know much about LT1's or pre-98 stuff... hell I know little about 98+.. haha
