Hi: I purchase a "09" Ford Escape 4WD to tow. First trip I got about 130 miles before the transmission burned up. Took 6 weeks to replace. Ford assured me that it could be towed without modification. Second trip about the same distance, once again, burned up the transmission. I left the car with a Ford dealer and told them that they would have to replace it with something that I could tow. Does the 4WD make the problem worse? Any help would be appreciated.
