Ok Gregg,
I am stumped and don't know what to do. The trans shifts great until you drive it for about 20 25 minutes. Then it will not shift. It will start to slide into second and go to third then forth and lock the converter up like normal. Then the next thing you know it will come out of 4th and drop to 3td while you are cruising. If you pull away from a stop sign after all this starts happening it will slide into second and then there is no 3td or 4th. It's a really bad slide into second to. If I go from 1 to 2 it will still slide into second. Still no 3td or 4th. I also lose Reverse. If I let the truck sit for about an hour, (cool off) I can get in and drive it like it was normal for about 20 minutes and the whole process starts over again. The fluid is good I just changed it, I put a new MLPS on the trans and it did not help anything. I don't think the trans is blow, It shifts great when the truck is cooler running I guess you can say.
Any ideas,
Justin
