Transmission Failure problems of the 2003 Ford F-250

Vehicle has 7. 3 liter diesel engine and the Ford 4r100 automatic transmission and 4 wheel drive. Transmission failed at about 88,000 miles despite proper servicing since new. It would intermitently stop shifting in normal use and began to slip badly. Only second gear was still working when I got it to the dealer the next day. The transmission was replaced at my expense ($3500+). The replacement transmission failed in a similar way at about 135,000 miles despite being serviced as required by the dealer. They are unable to obtain a valve body for this troublesome assembly and it has been at the dealer for nearly two weeks. This model of transmission is defective and dangerous especially if you are towing and lose engine braking due to the transmission failing. Ford no longer uses this transmission as it has a high failure rate. The body has rusted through at one of the cab corners and over both rear wheel wells. Ford repaired the rust through once under warranty but the rust throughs continue and have a negative effect on the integrity of the vehicle structure and protection of it's occupants in the event of a crash. A rusted body would not protect occupants as well as an an unrusted one.

2003 Ford F-250 (only 50,000 miles) had major transmission failure. Housing cracked and there is no way to repair. Only option is to install new transmission.

Transmission failed while driving. When stopping the vehicle it would not move in any direction. Had vehicle towed to nearest Ford dealership in shawnee ok. When the transmission was disassembled the inner pump rotor was broke as well as 1-2 and 2-3 shift valves were stuck. Milage was 3, 822. Nov 13, 2002. On Jan 31 2003 while going to the store the transmission failed to shift into drive or overdrive but would move in first and second as well as reverse. Had vehicle towed to place of purchase walt's live oak Ford where they have stated it would be a 5 days before it could be looked at. Ts.
