I am Joy and have owned GM all my life. Would never change. My question is on a 1995 Buick Riviera with an L67 and 4t60E transmission. We have acquired a serta approximately 2006 4t65. What I would like to know is can we exchange the final drive parts? We are aware that that 4t65 is all electronic. We will only exchange hard parts. Can this be done?
so glad I found you!
also, I read up on the 1995 Rivi with L67 and it said that the only trans would be 4T60E HD. That is not marked on the pan just 4t60E. Does that mean that it is or isn't HD? I was wandering if you could send me the manual on 4T65E so I can look at side by side, unless they use general pictures?
They used a generic pan on the 65. It also uses a beefier diff which is bigger. Only way to tell is by looking at the trans model tag when it comes to identifying. This will also give you the ratio also.
