Ok Chief:
You've replied to my post on flashing yellow differential warning light so I'll throw this out to you:
Thus far, I have changed tranny oil, filter and gaskets....replaced free wheel clutch switch, (MR953767)...and 1st time out on the highway today, 20 miles down I-85 it's flashing yellow again.....pull off, restart and roll for another 20 miles, and it flashing again? Any suggestion or opinion why replacing the switch did'nt solve my issue?
