Thread: What up my fellow pontiac lovers??

So will i need the hd diff?? Because my grand prix wont shift into 2 or 3 gear just first. I know its the transmission, i found a 1999 grand prix transmission with 80k miles on it for 200.00. But its not the supercharged version, so will i be taking a risk in damaging my car by using this tranny or should i just get mine rebuilt?

So i can use a 2001 transmission from a supercharged pontiac grand prix??
