What's going on??

This morning (-8F) outside, we got loaded to go ice fishing. Truck is running fine(2002 Expy XLT with 47K miles)---We get about half way there(60 miles) and I notice I'm running at 3100 for RPM's(Norm is about 2100)----Pushed the OD button and nothing wouldn't go up or down. Then we stopped for bait and when I started the truck again it revved up to 2100 and stayed there---Wasn't a good thing to put into gear. I decided to disconnect the battery and see if things would reset. Well after reconnect it was just fine---no problems. Got back to speed and went to pass someone and then it would only run in 1st or 2nd gear and I had to move the shifter to 2nd to get it to shift. Pulled into a gas station and turned it off to try again. Nothing.....It wouldn't start--turned over but nothing. Then checked the fuel relay and that was fine. 10 minutes later after wondering, WTF!, I turned the key and it fired up. Has run perfect since then. The check engine light did come on 2 times during what happened and has now gone off since it restarted. I'm hoping someone may have an idea. The truck is still under a 90 warranty since I just bought it a few weeks ago. If you have any ideas as to what might have caused this, I'd like to hear them. We did have allot of snow(12") yesterday and I was driving through that quite a bit(With no problems)----Thanks much!-----Ray(In Wis.)

If the CEL came on AFTER you discionnected the battery, I'd try to get the codes read. If not, your guess is as good as mine. I would have said transmission problems, if it werent for the high idle and FTS.

Thanks much for the reply. I too thought transmission but with so many other things going on, I just don't know----All I can say is that I hope this doesn't happen whenever it snows or during the cold weather because I do use it in 4x4 on the lakes and while off road hunting-----Hope I can find out what happened!----Ray

Sounds like what happened to me awhile back. I had a bad module inside the transmission that wasn't allowing the trans to shift properly. Dealer repaired it under warranty and have had no problems since.

I don't recall having as high an RPM reading as you have, but my tach was acting very funny and giving false readings. Pushing my OD button on & off changed nothing, as the trans was stuck in 2nd or 3rd - mine would not go into OD at all. It was almost like the computer "knew" what speed I was going and what the RPM's should be, and was sending that info to the tach, even though the trans had a mind of its own. Hope this helps, even if a little...
