Automatic Transmission Assembly

The cause of the majority of automatic transmission assembly failures is overheating. Typically overheating occurs when clutch discs in the clutch pack slip. When a high horsepower engine is driving a lot of power to the transmission input shaft, there needs to be quite a bit of hydraulic pressure on the clutch discs to hold them in place. For a transmission that can keep up with a performance engine, it's not only hydraulic pressure that needs to be high, there needs to be thicker clutch discs or more of them. 4 Wheel Parts manufacturing partner BD Diesel makes transmission kits with 25-35% more clutch material than the stock transmissions typically found in heavy duty pickups so the transmission can hold that torque under heavy loads.

Your off-roading vehicle has taken you up and down the steepest hills and through the roughest terrain. You have traveled a few years with your all-terrain rig and it's time to upgrade the engine. The check engine light has turned on repeatedly and you have experienced loss of power on some excursions. The engine has even stalled on occasion. Other signs of engine troubles can be if the engine continues to run after you turn the ignition off, or if it sounds like it's running rough. 4WheelParts.com has you covered.
