4T65-E...

[chevyguy3100]

I have a 96 Lumina w/ a 3100 SFI, and read somewhere (that I can't find now) that the tranny out of a 98+ GP GTP (4T65-E) will bolt up perfectly. I was wondering if this is true for my engine and if that is true concerning all parts (axle, wiring, linkage...) I preciate any help. It's just that these 4T60-E's are not working! And it looks like that would hold up much better to my driving and mods.

It might bolt up, but thats about it.

 

The internal electronics are different, and the final drive may be different. The final drive issue could be fixed with a chip, but the electronics might not be able to. Maybe some custom work?

 

Of course with a 4T65-E you bring other problems to the table...mainly solenoid failure. I've seen way too many 65's with solenoid failure, 80k, 90k, 100k, even 55k miles and they need new solenoids.

 

I say your best bet is to rebuild your 4T60-E. It would suck if you went through the trouble of switching transmissions, and the new one wouldn't work. Your 4T60-E will hold up to quite a bit of power...

Oh, that's same problem with the 60-E, solenoid faliure. Oh well, I guess I'm gonna rebuild the 60. Preciate it!

Really? I don't see too many 60's with solenoid failure...mainly 65's. Oh well, good luck.

You can use a 4T65-E if you use a PCM out of say, an 2000.

At some point GM replaced all 4T60-E's with 4T65-E's. I'm thinking 2000 but I'd have to look it up to be certain.
