I owned a 95 f-350 crew cab 4x4 with the auto and the 460 gas.I used this truck for work both on and off road. My average G.V.W. averaged about 9000 to 9500 lbs. The tranny went at 56,000.Fortunately I purchased the extended warranty and Ford repaired it no questions asked. The service writer did inform that there were some problems with that tranny.On a better note I am now driving a 96' ,same package,same workload, 72,000 mi. no problems.
