Optimized your transmission's performance through recalibration without having to remove your transmission. Most stock automatic transmissions are unable to downshift into low gear above 15 mph, and automatically upshift at a predetermined speed no matter the gear. With the Transpak, you can downshift at any speed, while holding the transmission in first gear during any speed that you desire! This is an asset when you've got a modified engine, and you want to maintain high RPMs. Simply select the most fitting mode for your application thanks to all the features in the Shift Improver Kit, plus additional driver manual control. Stage 1 Heavy Duty is for street rods and normal passenger Fox bodies. This stage provides normal automatic operation when in Drive with a firmer, but not harsh, shift feel. Stage 2 Hi-Performance Street is for full performance street use, essentially the same as Heavy Duty mode except a quicker shifting. Retain full automatic features and standard shift points with selector in Drive.
