Jasper rebuilt this tranny about 5 or 6 years ago

Drop the pan, see what you find. If nothing "Bad"™, adjust the bands, change the filter. If you are feeling really froggy, change the governor pressure sensor and solenoid as well.

Edit: Try this first.

Crawl under the truck, find the 8 pin connector about halfway back on the drivers side of the trans.
Unplug it.
Go for a drive. You will have to manually shift gears. Run it thru the gears once. (or twice.) You won't have O/D, or TCC lockup, so, don't go far, and don't tow anything.

if it works ok that way, the above suggestion (with the electronics) should fix it right up.

Will try it when i get a chance maybe today will keep you posted...👀
