Re: 6.0 SURGE ISSUE?
I've had a surging issue when towing a my 10K , 2K tongue wt aluminum gooseneck w/ my 2005 2WD 6.0 F-250 9800GVWR 33K miles. I've noticed it at 55-65 on bumpy roads and less than 45-mainly when braking on bumpy or smooth pavement. Some call it highway hop or porpoising, but I call it a pain!@. Been to 2 local dealerships and the trailer shop twice. Dealers reprogrammed transmission and injectors, trailer shop reset brakes and now believes the Integrated Trailer Brake Controller is probably faulty. Just had the 30K service, transmission flushed and filters changed. Traveling with the trailer to the original dealership on Friday. Let us know if you find out anything-I will inform if I solve my problem.
