To cope with the additional power and torque from Pontiac's new V8, the domestic brand has employed a strengthened version of GM's trusty Hydra-Matic 4T65-E four-speed automatic gearbox. Although it shifts smoothly, and comes equipped with TapShift 'manu-matic' functionality, the transmission seems a little outclassed in this day and age of 5- and 6-speed automatic gearboxes.

In order to make the most of the new powerplant, Pontiac revamped the suspension system of the Grand Prix for GXP use. The GXP employs high-performance Bilstein struts for improved damping, while springs with a higher rate cut back on lean and squat. Pontiac has also dropped the ride height by 9 mm (0.4 in), and has added a 17.2 mm (0.7 in) diameter hollow rear stabilizer bar to further improve handling. Countering the forward thrust of the motor are a set of upgraded brakes, 323 mm (12.7 inch) cross-drilled discs up front and 305 mm (12.0 inch) units in the rear are standard, and are acted upon by high-performance twin-piston calipers. A state of the art four-channel ABS braking system by Bosch is standard.
