Has anyone had a problem with 5R110W direct clutch problems, My nephew had his 2005 SD f 250 6.0 be told that 5R110W direct clutch problems. He was towing a trailer in tow mode and it started slipping in and out, so he took it to a dealer and they said that it was the direct clutch that was causing the problem and needed to be rebuilt, he only has 40000 miles on it but they said that it is out of warranty. What do you guys think that he should do?
