Wierd Transmission Issues
 

Today my truck started doing something strange. I was waiting on a train today and put my 06 F250 6.0 in park. When I went to put it back in drive, I noticed the check guage light was on and so the temp guage was way up there. So I pulled over and started thinking. I had reprogrammed my truck a couple days ago and something didn't seem right about the upload so I put it back to stock and it looked ok. I drove a few miles and all of a sudden the temp on the transmission jumped up again. Pulled over and waited 10 to 15 minutes. Then it registered a normal temp again and drove a couple miles and it went back up. At this point I had someone just pull me home.

Do you guys have any idea what could cause this? Could it be the programmer? Could it be the transmission heat sensor?

So I decided I would check and change the transmission filter so I took it off only and went and bought another one. When I went to buy the Transmission fluid I did not realize it was going to be a scavenger hunt to find the correct fluid. It requires the SP fluid. Where do you guys get your tranny fluid?

Sooner......That's MERCON SP fluid. Any parts house should have it, or FORD, but it might be slightly higher priced.

O'Reily's, NAPA, nor Advanced Auto parts carried it.
