Hi all, I have been browsing over the forums for quite a while and found many similar problems but no real definate answers, and really need your help.
I have a 91 celsior, the TRC light is coming on when I give it a bootfull and with TRC turned off. The transmission will then not kick back out of O/D when I need it to, in fact it wont drop back at all. It will accelerate smoothly through the gears, albeit wanting to drop into o/d rather eagerly. This problem does not exist if I baby the car around. I have run the diagnostic test, coming up with 62 and 63- no 1 and no 2 solenoid issues and both a tps signal error from the TRAC system and the engine ECU. So I did a reset and went for a drive, car started playing up as soon as the speed got up a little and sure enough the TRC light came back on and the auto started playing up. Got home did another diagnostic, only codes that came up were the TPS codes once again from the TRAC system and the TPS from the ecu??? Any ideas guys, will a bad TPS actually cause this? Cheers, Justin
