stalling in reverse

[RHFDpowerstroke53]

Hey,

I have an F5 Chip on my 01 and sometimes when i shift into reverse (auto trans) the truck will bog out and come down to around 500rpm and sometimes itll die but sometimes it'll come back. I think the TC is locking up too early or something. have you had this problem before? i got my chip in late dec.

Check your trans fluid level, Mine just was doing that after I changed valve bodies and i was low on fluid. Filled her up no problems now
