98 gtp 4t65e-hd

I'm running a 98 trans in my 01, the cooler lines were the only real issue.

Yep just as the other guys said you will be fine as long as you use the correct cooler lines for the 98 trans, everything else is the same as long as it IS really a 98 GTP trans. It should have code "XA" on the ID tag on the back side of the case, if it is not an XA then it is not a GTP/GS trans.

And let's not forget the big 8 on the tag to denote a 98, right Dave
