The Impulse with the G200Z motor has a 4 speed auto that will bolt up.
The turbo and 2.3L impulse also has a 4 speed auto but the flex plate and crank bolt pattern are different.
Any vehicle with a G180Z or G200Z the trans will fit.
Any vehilce with an 4Zxx motor will bolt up to your stock motor but the crank pattern is different. its 8 bolts instead of 6 bolts in the GxxxZ motors.
