I've cooked my tranny in my 94 Z28 (stock 4L60-E) and I'm planning on just trading this Z in and upgrading to an LS1 - what tranny do they put in this beast and what are they rated to handle in the terms of HP and tq? Thanks gang!

4L60e

 

same thing you have there in your 94 4l60e

 

Get a 6sp.. I went through 6 autos (all 4L60E's) so I went straight for a M6 since I knew that they were stronger and easier to work on.

 

a t56 is pretty much bullit proof up till 500hp

 

Tell that to everyone who's had had to rebuild them with less than 400rwhp. Quite a few people in my club have had problems with the Tremec T56 and I know they're not the only ones. It doesn't take much to break them, just a little power and a little abuse.
