I was thinking it had something to do with that inline fuse on the violet wire coming from the PCM that I noticed. When I was driving my 99 today to the park today after finishing the underhood detailing job I've been working on for two weeks it throw a code on the way there. It went off half way there and then on the way back it came on again. It never went back off even when I shut the truck off and restarted it. However, my scanner somehow picked up the pending code for the transmission but it won't read a transmission hard code. So I assume it's still the P0711. I'm wondering if something I've overlooked the whole time I've had this truck is to replace the 20+ year old transmission control relay. It's the original one. Actually looks like all the fuses and relays are original except the starter because mine actually would try to start on it's own a few years ago. Is there any easy way to check these? I could just swap them or should I replace all of them?
