Good Morning. I recently bought a 2002 F250 CC 4x4 V10,I pull a 29ft. Jayco travel trailer with an approx loaded weight of 7000-7500lbs. Has anyone out there towed in O/D pulling this kind of weight??? I would never dream of it in my old Super Crew F150 5.4 3.55. Thanks, Steve
I turn off the OD at the bottom of the hills and bring the rpm up for the climb. If the load is too much the tranny will shift out of OD into 2nd or 3rd when needed. I know my truck and I can tell when it needs to shift so I use OD accordingly.
I only use OD on the flats when I know the trannie isn't going to be shifting back and forth between gears. I know 3 people with Fords, 2 PSD and 1 V10 that used OD all the time and burned their trannies out at $3,500+.
Tow in the tallest gear that the torque converter will stay locked. If the torque converter unlocks the heat will build up immediately. Get to know your truck and downshift the transmission manually when needed.
Also consider a Banks TransCommand or similiar system built into better programers like the predator. My TransCommand eliminated "hunting" as MarkMoore said completely while towing.
