Re: HG's Bigass Farm Truck
Changed filter, temp sensor, shift solenoid, added aux cooler and tranny repair in a can. No real improvement.
The transmission keeps going into hot transmission mode at normal and lower temperature. Drove about 30 miles and it went into that mode 3 times. Highest temperature was about 187f which is normal. The high fluid temperature shouldn't happen until the fluid is at 295f for 30 minutes. If I shut it off and restart it goes back to normal operation and then hot mode again a few miles later. Other than that it seems to operate pretty normal mechanically.
Online search is indicating that this happens on swaps and is a programming issue or the ECU itself has issues. I'm getting some other trouble codes related to the fuel level sensor, which I don't think is even connected to the ECU. So I think the next step is going to the local shop that does these swaps routinely and have them check out the ECU and programming.
