Nothing has gone wrong with the car since I have owned it.
My car originally had the 3.1 V6 but I decided that I wanted an even faster car so I took the supercharged 3.8 from a 1998 Pontiac Grand Prix GTP. This car is beyond fast now. Oldsmobile really knew how to build there cars because the it can handle this engine really well.
What year is your Pontiac engineer? Have you had any transmission issues? Would you recommend keeping the original Cutlass transmission and putting it on the Pontiac engine? Please e-mail kwodem@gmail.com.
Thanks.
