Recently bought a 1994 Ford F250 XLT RWD 7.5 L 460
83,000 Miles Original
Recently has started to randomly shift Chunky between 1st and 2nd
and Chunks from P to D and P to R
If i unplug the battery and reset the memory, it shifts good for a couple days then goes back to the random chunks
bought a code reader and it spit out Code 628
Torque Slippage
does not look like Transmission Pan has ever come off this thing. Fluid smells slightly burnt, but not overly
Should i start with a full transmission fluid flush?
Or think its Torque Convertor?
Or simply a sensor?
if anyone has had this happen to their Truck…
looking for suggestions before i start with the Flush!
thank you so much

E4OD not taking off in automatic 1st gear
Any insight as to why my transmission will not take off in 1st gear when using automatic drive? When pulled into manual low it works fine. Any help is much appreciated, have replaced the solenoid pack several times and on rebuilt PCM number 3 chasing this issue. Have also done the shifter handle and wiring and put new bushings in the steering column. Any ideas?
