I've done the search and don't seem to find exactly the same thing for my year.
Now the transmission is behind a 1993 6.5 TD 2-wheel drive dually. Mechanical Injection.
Newer TPS already. 100k miles, 4.10.
I keep losing Overdrive. I can shut down the engine and get it to reset most of the time. But yesterday the temperature outside was 85 and it would not stay in OD at all.
It will be fine in the cool morning air and all the way to work (40 miles).
Coming home on warm days (+75) the transmission will start off with a HARD shift between 1st and 2nd. And the shift points are higher too I believe.
When this happens I already know I won't have OD. Mostly I started to just put it in neutral and turn off the key for 10-15 seconds.
Sometimes it will start to "hunt" when I'm speeding up, then just dump the OD. In the warmer weather yesterday it would just slip out of OD for no apparent reason for the short time I could get it engaged. Sometimes it will be fine until I come to a stop because of traffic and then I'll feel the hard shift to 2nd and I know I'm not going to have OD again.
This problem has been with the truck for at least 5 years or more. I just started to use it as a daily driver recently and noticed the effect the warmer outside temperature had.
Thanks
