Just took my WJ out through the snow (watching the 2wds slipping and sliding and of course feeling very sorry for them as they didnt get a Jeep before the snow and ice hit, anyway, i digress....). Turned on the ignition and my MIL stayed illuminated and has turned up a new fault code. After doing the on/off trick I pulled out p0700. From wjjeeps it says:
P0700 (M) - Check Transmission DTC's - This code indicates that the EATX (Transmission controller) has an active fault and has illuminated the MIL via a BUS message. The specific fault must be acquired from the EATX via a DRBIII tool. (Input or Output Speed Sensor failures often cause this code and are a common failure part on WJ Grand Cherokees).
Anyone else ever had this on their WJ and if so did you replace the speed sensors and it fixed the problem, or did it turn out to be a different fault? Can anyone recommend some software or a tool that can read the transmission controller codes without me having to pay uber money to the dealer?
Cheers
