U0103 — Lost Communication With Gear Shift Control Module "A"
U11E3

Used transmission installed from a 2014 Jeep Grand Cherokee that has DTCM ( Drive Train Control Module), Codes setting for module that this vehicle is not equipped this vehicle is not equipped with a DTCM Cal id in used TCM is …AG , original trans on floor...

Any tips or tricks to get this to allow programming of proper cal id appreciated, I did try restore config , and also tried to Id with tcm powered down/ unplugged , however pulls calibration as soon as powered up. 

FIX: ID using WItech with original valve body plugged in. I was hoping to find another way of doing this. All Dtc's cleared and it goes into gear no problem.

You may be able to alter VIN with CDA. These are one time use so Chrysler locks them down.

Hi Michael, The vin number in the module was updated when restore config was completed. Thanks for the response.

That is great to know that a restore vehicle configuration worked. The last one I tried would not take a PROXI learn or restore vehicle configuration. The customer ended up swapping the original valve body into the donor transmission. Until swapped, the transmission would not come out of park.

Brian, Call my shop tomorrow morning. I should be there a few hours before I hit the road. As long as you have the original valve body we should be able to make this work. This vehicle should have a 845re trans in it. Let my kid know I told you to call me. She screens all my calls from spooner shops...lol

It is interesting which vehicles will work and which ones wont. I failed to mention that this one would not come out of park as well. (I did get a little risky, as with TCM off of original trans, it did not recognize park and I could not turn key off, so just unplugged and plugged in used trans). I have some things i have been messing around with a few used transmission for a '16 200, and its…

I was having an issue where it wouldn't reconize park and the push button will not shut off. I couldnt program the reman transmission. We had to call another mobile guy out and he said to reset the WCM and it will shut off has anyone heard of this? After he did that that he was able to do the programing, Didnt have original transmission went back as a core.
