I have had 2 fault codes that are always active and have been in the truck as long as i have had it. I was wondering if anyone else has this? Should I worry abotu them? The codes are 12 (bat dissconect within the last 50 key offs) and 37 ( trans temp to high, trans temp voltage shorted, tcc lock up circuit mailfuction( i dont rember the tcc one correctly)).

has anyone dealt with these? my manual doesnt have any trouble shooting steps for them. thanks for the help.

The 12 is normal ... the 37 is not. Here's a lot of information on OBD I vehicles. Might even find a fix for yours. http://ezinearticles.com/?OBD1-Codes...&id=188014

 

Yes I have, ck the connection at the transmission. If its okay then replace the lock-up solenoid. Need to remove the valve body to replace.

 

the converter locks up and unlocks when im driving. It seems normal also. I might give it a shot and switch out the switch. Thanks for the help
