Ok gentleman, specifically the XJ crowd, my 97 Xj is havin some electric problems, mainly dealing with the AW4, it seems to be hunting gears and down shifting at random, I looked on diffrent sites, did thier recomended tests such as disconnect the tcu, readjust the tv cable and such, with the tcu disconnected it drove fine, shifted with the selector, didn't slip. Reconnected the Tcu and it started messing up again. Checked codes with the key and got a few codes: 12, 22, 45, &66. 12 is the battery which I replaced a few weeks ago, 22 is the coolant sensor, not sure why it came on? I did disconnect it last night for about two hours? Code 66 is saying that the TCU is not sending signal to PCM. Im pretty sure this is why its acting funny but I'm not sure how to go about it? Has anyone else had this problem? Any suggestions? I'm going to borrow a code scanner tonight also, not sure if it can give me more specific codes or not. Any help is appreciated
