Hey, I just acquired an '89 XJ and wanted to know a few things about the sensors and PCM on that sucker. If I disconnect everything having to do with the AW4 transmission(TCU, Gear Selector Switch, Transmission TPS, Trans Control Assembly), will it throw an engine code? If so, will I need to ground one or more of the sensor inputs?
It's going to be a tow vehicle. I'm dropping a 5-speed in it and want to pass smog without a check engine light.
I'm pretty good with electronics and I know I can solve any engine issue on the spot but if any of you have been there before, the heads-up will help.
