Hi guys.......I'm sure this has been asked before, but need an answer if anyone can help. Is a 2006 2WD truck 4L65E a direct swap into a 1999 Z-28 4l60e..?? I know there are some input / output shaft differences to be considered.

Thanx in advance for the help..!! DK

 

You would only need to swap the tail housing and the manual linkage rod at the the side, Other than that its a direct swap.
The truck will have a smaller 2nd gear servo so I would swap that also .
