will try to figure out the TCU codes this weekend, Thanks for all the replies!

No CEL, bought the car second hand. Is their any immediate damage in driving the car?

I unplugged the trans plug and drove in tight circles no AWD, even jacked up the front end and made sure, just the front wheels turning... So what is next?

Will try the trans wiring harness un-plug when I get home! Thanks again, JSB

speedometer works fine, driveshaft intact, transmission behaves fine just no AWD??

Yes, I have just purchased a 96 wagon, with 182K, with only FWD, with fuse pulled, and trans serviced. I am considering the center diff lock switch to troubleshoot the problem? Also the a/t temp light flashes @ 15 times upon starting, but the trans shifts good and does not slip?? I am not a serious mechanic or electrician so keep it simple. Many thanks JSB
