I have a '93 F350 7.3 aftermarket banks turbo, 4x4 crew truck with E4OD trans. 155K miles on the truck. I am not a mechanic and the transmission needs rebuilt. The Seattle area Transmission shop I took it too says about $4500 for a heavy towing transmission rebuild (shift kit, triple clutch torque converter, new trans cooler). Does this sound about right for a rebuild? Any suggestions on Seattle area shops for a second opinion. Seems crazy to pay 2/3 the cost of what I paid for the truck for a transmission ($6500 7 years. ago). But not to many 7.3 crewcab trucks for under 15K in my area.
