So I have a 1996 Oldsmobile Cutlass Supreme SL that originally had the factory 3.1 V6 but now it has a 3.8 V6 from a 2005 Pontiac Grand Prix and the trans has been acting up lately, is it because of the engine or is it a common problem with the stock transmission?

It is just a problem with the transmission and it is old.
