My father was the first or second man in the Nashville area to work on HydraMatics, back in the late 1940's. He's 87 years old now, and has been retired for some time, but he's still very sharp on diagnosis. What's yours doing, and have you tried to adjust the throttle pressure like I suggested the last time you mentioned you were having problems? If the transmission actually needs an overhaul, I might be able to help you out. My farm is about 80 miles west of Chattanooga, between Pulaski and Fayetteville, near US highway 64. Drop me a PM.
