Need transmission help please. PLEAAASE
As some of you know, I'm pretty sick. I had a brain tumor removed last year and I'm moving to a smaller house, in a small town, on a small lot. I planned to tow one of my cars across the country behind the F150. Unfortunately, I have a small problem... After my transmission heats up, it only has 1st and 2nd. For the first 30 minutes of driving it's fine - perfect even. The fluid looks great, slightly overfilled.
After 30 minutes or so, it starts to shift a little harsh and a little late, then the OD light flashes and it spits out p0781 p0782. After that it shifts out of first into 2nd fine, but that's all I get. If I rev it up and let off, it coasts like it's in neutral. I'm super close to selling this thing if anyone wants to tempt me.
Should I post this in the F250 section? It's a 2001 6.8 V10 with a unknown year 4R100 4x4. I had a canned tune on the stock 2001 F250 SD PCM, but removed it.
