transfail safe

[johnnytime21]

Hello everyone, well I'm stumped, recently I dropped my 4.4 off at a local electronics shop to have a xenon replaced. When I picked it up the battery was almost dead, not fully though, it did need a jump, which he did with a box. Everything seemed fine but then the tranny acted like it was slipping. Then the fail safe. So since then I've disconnected the battery for at least an hour and unfortunately the problem remains. Every time I start it failsafe is gone until the tranny acts up again which doesn't take long. Any ideas would be awesome thanks everyone.
