early 99 f250, 4x4, auto 4r100, SRW, 220,000miles, 7.3 diesel. I was towing a trailer and the truck kicked out of overdrive and the off light started flashing on the shift lever. So I continued to drive and it then went to neutral. I coasted to a stop. Temp was normal~175. Trans fluid was at full mark and red, not burnt. So I shifted the the truck in all gears and nothing. So I shut it off and when it started I had first gear only. When I shifted to second it went back to neutral. Turned it off abd started it again and 1st only. So I drove the last two miles in first gear. When I made it into the 1/2 mile long driveway I shifted to 2nd and it went. Then 3rd but still no od. The trans acts like it is lost. I took off again and it took off in 3rd gear and never shifted. This sounds electronic. Codes p1249 wastegate, p0470 exhaust pressure sensor, and p1728 trans slip error. I drove it three miles today and it shifted all over the place and heated up to 210. Seemed to be a noise fromm trans inspection cover while it was idling. Anyone have any idea?
