D7F Transmission over heating after 3-4 hours
Hello RC, thanks for this. I haven't checked the Transmission pressures, I don't have a Manuel as i have never been able to find the correct one, yes the output shaft is still spinning and the transmission is slipping, it could well be the steering clutch and the driver is telling me brakes. -
