So yesterday I was driving the truck on the SPRTN 250 early lock tune and decided to mash it from a stop sign...it spun and shifted thru 3rd fine and then acted like it wanted to downshift once it caught traction but when it went to downshift it would just rev and not accelerate like it was stuck in neutral or between gears. I pulled over and came to a stop then tried to re-accelerate. It started to accelerate then it did the same thing like it was stuck between gears then it slammed into gear and threw the wrench on the dash. From there it would shift 1-2-3-4 but would not go into overdrive.
I pulled up these codes on the dashdaq: P0766-Shift Solenoid D Performance or Stuck Off and P2703 Transmission Friction Element D Apply Time Range/Performance.
I limped it home, turned the truck off, cleared the codes, and retuned it with the 250 late lock tune. I tired to gradually accelerate thru the gears and the same series of events took place. It also feels like the converter is slipping real bad in reverse. I let it sit last night, went out this morning and same thing.
Specs on the truck: 09 F-250, SPRTN 250 daily driven, Intake, Exhaust, Stock trans and converter, 55K miles.
Any input is appreciated. Thanks!!
