Mx 135 Starts... I think its Powershift Clutch Issue!!

This is a raw troubleshooting update, not a review: an MX135 owner documents an intermittent no-start problem that seems tied to the powershift transmission, testing whether putting it in fourth gear kills the engine and discussing community suggestions about the return line valve, drive shaft disconnection, and a possible shifter switch short. It ends unresolved, with the owner still planning to get it looked at. Useful mainly for other MX135 owners chasing similar electrical or powershift-related starting faults.
