'computer' issue??
here goes...
went to start my truck the other day and i noticed the odometer did not read. so i shut it off..and restarted. same. so i went with it cause i need to get home. as i was driving off, the trans shifted at a really high rpm and pretty rough shift. the overdrive light is blinking off and on...and the speedometer is not registering. there are no other warning lights on whatsoever..not a battery light..nothin...just the o/d light flashing. oh, and the door locks don't work...weird thing is that when i push the lock button, the parking lights come on as long as i am holding the button. this morning there was no problem. drove a couple places today and no problem. got to work, it happened again...as i parked it. it drove to work fine..no shifting problems..nothing. parked it, then i had no speedometer/odometer and couldn't lock the doors.
didn't correct itself yet.
is this a 'computer' issue???
i guess could take it to autozone and ask them, but thought this would definitely be the better place to ask.
thanks in advance!

Wow that is some kinda problem. My guess is that it isn't a computer problem since it involves the lights and locks but I could be wrong. I would start under the dash and inspect the wires very good and see if anything is shorted out or burnt. Check all the fuses. Look under the hood where the wires come thru the firewall for problems. Other than that one high RPM shift does it run normal?
Others will be by soon to help with pics and ground locations.

glitch?
yes, it is keyless entry...which doesn't work when this problem is happening. everything else works fine..and when the problem isn't 'happening' then everything is great..shifts normal..no problems..keyless works..locks work. everything. i guess i'll go to autozone to check.
ohh..and the fuse..that's what i was gonna check in the first place too, but being that it 'corrected' itself and then screwed up again..this wouldn't be a fuse problem right?
:sighs:

#8 fuse
ok..i checked the #8 fuse........it is still 'complete' but one of the prongs was crooked. not that that should cause the problem, but i took it out...straightened it and put it back. no problems now. could the problem possibly 'fixed' itself overnight?...i dunno. maybe it is just the #8 fuse...maybe it was trying to wiggle out of the 'clamps' that hold it in place and with vibrations and whatnot, it decided to cause some problems.
question is...(which i haven't tried yet)...if the fuse was bad or just taken out..would i have the same problems?
i suppose i could try.
thanks for the #8 suggestion!!

Probably not a fuse but stranger things have happened. Check the fuse then if its ok unplug the keyless entry module. It under the dash directly behind the cubby. It has three long flat connectors on it stacked like a three man pyramid. I have had the module go bad which blew the fuse and rendered all those items dead. Perhaps the module is going bad or the wiring to it.

If the fuse was blown or taken out all those thing still would not work. Maybe there is a wiring issue.

Unplug it for awhile and see what happens.

Does the trucks have lighted buttons?
I ask this just do to the fact of a possible feedback short from the drivers door. The wiring from the drivers door to the piller takes a beating over time.
In the E-series its a common problem in the rear doors.
It will even blow out the speakers.
