Truck won't hold 2nd gear when towing
Just got a 99 crew cab f 250 7.3 and I noticed when am towing, the truck won't hold 2nd gear.
When I pull out (even on a hill), 1st gear winds out nicely with turbo and then it shifts into 2nd gear for about 1 second and then quickly shifts into 3rd gear. When that happens, i loose my turbo and the truck is now lugging with very low RPMs until the turbo eventually kicks in and then I am fine. i am towing with the overdrive off (not like it matters in 2nd gear).
I have heard 2 things told to me. one guys said yes, it is a tranny problem and that it is slipping out of 2nd when it has a load on it (it seems fine if I pull out normal with no load). Another person said it sounded like i have a turbo problem. Can anybody give me their input into the matter.
I would like to go to the shop and have a pretty good idea about what may be wrong. Thanks.
