This transmission is equipped with Abuse Protection Valve Body. To shift into Reverse (R) or
Forward (F), all three of the following conditions must be met:
1. Throttle position must be less than 25%.
2. Engine RPM must be less than 1500 RPM.
3. Vehicle speed must be 0 MPH.
If any of the above conditions are not met, the transmission will be placed into a neutral
state until all three conditions are met. This neutral state may slightly drag the forward or
reverse clutch, moving the vehicle very slowly and give the impression that the transmission
is slipping. To fully engage the desired gear, simply come to a complete stop with the engine
at idle.
