After reading through different threads, i have come upon the realization that during the lt1 years, the 4l60 went through some changes. Which year trannies are compatible and what not and what changes were made? I searched but didnt come up with anything.

 

You could write a small book on that , but later today if no one else has addressed this I will do a quick summary for you

 

Basically, i want to know what i can use with my 94 z

 

93 94 and some 95s will be exact swaps, the later models can also be used with some minor modifications up to 97
