Default Help !

Hi guys
Iím currently towing my 5th wheel home and went into limp mode( not sure why ) I cleared the codes and drove to a rest stop. This happen a few years back. I cleared the codes and itís been fine since. I donít beat on the truck and the tunes are turned down. Iím gonna stay at rest stop over night in fear of breaking down on these Virginia hills. Truck only has 45k on it. 04 lb7 if my signature doesnít say. Any thoughts would be greatly appreciated as Iím nervous to continue on!
Thanks for any advice!!!
Mike

01-05 trucks didn't hold much power especially towing heavy did it happen on a 4-5 or 5-4 shift? If you keep it from making those two shifts under much power it might be ok but that's a guess with no codes.

Iím pretty sure I was already in 5th but I can be sure. I know itís impossible without codes but maybe you can answer me this. If it were to happen again especially pulling a hill would the transmission completely go or would I be stuck in limp? Would I be better manually shifting in like say 3rd and take it slow just to get to safe ground?
I really appreciate your replies!!!

Keeping it from shifting into 5th on the hills will be a good start !

When it happened was it limited to 2k RPM's or was it stuck in 3rd? That will at least help figure out if it's a fuel limp vs trans limp.

Honestly it happened so fast. I would say it was stuck in 3rd. I just remember it tacking up before I pulled over

If it’s limited to 2000 rpms It’s a fuel limp, if the trans limps it’s stuck in 4th. Tow a heavy camper on a stock tune only, or downshift to 4th before hitting the hill.

I thought the 5spds limped into 3rd and not 4th?

They almost always do. I've seen some weird TCM problems that would command 4th, but that's rare.
