Tranny issue while towing?
The reason I entered a question in the title is because I am not 100 % sure it is the tranny.
Yesterday, I pulled my 6000lb travel trailer home from a trip in the mountains. The pull to the mountains is 7000 foot gain at an average of 8% grade. It is steep. I put the truck into 2nd gear with OD off. It seamed to maintain this well, however pedal was almost to metal.
When I got home after going down the grade in 2nd, and then a little highway driving, I got home, and the truck sat for about an hour before I hauled my TT to storage. I started out and wow, a huge loud whiney scheeching sound. I let off the throttle and it went away. I tried to re-create this on the way but it seemed solid and normal.
What the heck was that sound?
Anyone have the same or similar experience?

1. why did you have the stick in 2nd gear? engine braking down hill?
there is no other reason I can think of to do that unless you're on a boat ramp. especially as the throttle curve gets re-mapped when you put it into 1st or 2nd gear. that's why you were flooring it. the e-throttle gets chopped in half and the pedal becomes alot more responsive than it is in Drive2. agree with 442w30, it sounds like a belt to me

Tylus,
With my 06 left in drive and O/D off the trans hunts for gears bad. It is a constant struggle between third and second my trans temp also shots up to 240 degrees when this happens. In second gear 8,000 lbs and a 7% grade floored I see about 40 mph and trans temp stays at 195.

wierd, but makes sense I guess. sucks that the throttle gets remapped when in 1st or 2nd though. it would give you a bit more performance if the throttle stayed the same as if it was in D

Hey thanks for the input. Sorry I didn't respond sooner. I got stuck on an airplane and sent out of town for work for a couple of days, and haven't even had time to check my private e-mail.
Yeh, pulling 6000 lbs at what now I have learned is 9 to 10 percent grade, the tranny just hunts to much, so I stick it in 2nd and take it easy, but sometimes I have to almost have the pedal floored. Especially when I get close to 8000 ft, where the air thins out. I love my F-150 and the set up I have, but I sure see why folks like them oil burners for pulling in the mountains.

Oil burners?
Are we talking old junkers with bad piston rings, or is this some random slang for diesel?
Cause if it's about diesel...it's completely wrong.

oil burner has been sononamous (sp?) with diesel for at least 30 yrs now.
it's a reference to the fact that you can pour 100% frying oil into the gas tank of a diesel and the motor will run. the filters/injectors won't be happy, but the motor can and will run on pure oil. in fact there are quite a few cities that use old fryer grease to power their garbage trucks
