I recently repaired my tuff torque transmission with a new main spindle bearing. After some cycling, the transmission appears to be working fine. Moves quickly forward and backward when pressing pedal. Also stops when releasing pedal. When mower is off and transmission engaged (not bypassed) it will not move backwards as expected but does move forward as if it is in bypass mode. Is there an adjustment to prevent this? I don’t recall it doing this before I repaired transmission.
