2002 Pontiac Firebird Transmission

Specifications

The Pontiac Firebird transmission is configured with a rear-wheel-drive transmission that varied by engine and trim. Most V8 models (like the Formula and Trans Am with the 5.7 L V8) used in a 4-speed GM Turbo Hydramatic 4L60-E automatic gearbox with overdrive, designed to balance smooth shifts and highway cruising efficiency. This automatic unit has four forward gears and electronic control for shift timing and torque converter lock-up. Some Firebirds especially less powerful V6 versions —were offered with a 5-speed manual transmission, which lets the driver manually select gears and often provides a more direct driving feel. The choice of automatic or manual depends on the specific trim and engine option, offering you race-focused acceleration.

Engine Variants

GM 4L60E

The GM 4L60E is configured as a four-speed, electronically controlled automatic transmission with a torque converter, featuring gear ratios designed to balance acceleration and fuel efficiency, including a fourth-gear overdrive for reduced engine RPM at highway speeds. Its electronic control unit manages shift timing, line pressure, and torque converter lockup, allowing smooth operation and adaptability across a wide range of driving conditions. The transmission is typically paired with V6 and small-block V8 engines and uses a hydraulic system enhanced by electronic solenoids for precise gear changes.

Tremec T56

The Tremec T56 comes equipped with a six-speed manual transmission with a robust aluminum housing, close-ratio gearing, and a direct mechanical clutch system for driver-controlled shifting. It features two overdrive gears (5th and 6th) to provide strong acceleration in the lower gears while maintaining low engine speeds during highway cruising. Designed to handle high torque output, the T56 includes synchronized gears for smooth engagement and is commonly paired with performance-oriented V8 engines in rear-wheel-drive applications.
