ABUSE PROTECTION VALVE BODY
Often times the operator causes the most damage to the transmission, reducing the service life and causing costly repairs and downtime. The PCS 4L70 abuse protection valve body protects the transmission by locking out reverse engagement until the vehicle is stopped and the engine is at idle. It also prevents "neutral drops" by only engaging the forward gears when the engine is at idle.
The PCS valve body disengages the forward gears when the vehicle is stopped and the brake pedal is pressed. By reducing the number of rotating components during idle, fuel consumption can be reduced especially for vehicles that spend a lot of time idling in gear. With the forward gears disengaged, the reduced brake force required to hold the vehicle, especially in high gear reduction drivelines, can significantly improve the drivability of the vehicle from the operator's perspective.
