Overview:
The Transmission Controller detected that the Shift Finger position indicates neutral and a comparison of Input and Main Shaft speeds indicate the transmission is in gear. The comparison of shaft speeds is only performed when the vehicle is moving and a shift is in process. This fault can only be set during a shift, and becomes inactive after power
down.
Detection:
The fault is detected after the Transmission Controller powers up and a non-neutral condition is detected during a shift.
Fallback:
This fault causes an in-place fallback. The transmission will remain in current gear.
Possible Causes:
1) Worn internal transmission components
