burghere66 Posted July 26, 2021 Share Posted July 26, 2021 Trying to track down the location of the Transmission Control Module. My transmission has lost it's power. I'm at Interstate Power Systems in Omaha where they are working on it. Gary B. 2002 Monaco Windsor PBDD Link to comment Share on other sites More sharing options...
Brett63 Posted July 26, 2021 Share Posted July 26, 2021 It should be right on the side ot the transmission. typically on the drivers side of it. Link to comment Share on other sites More sharing options...
burghere66 Posted July 26, 2021 Author Share Posted July 26, 2021 We found it inside the panel just to the left side of the drivers seat. Gary B. 2002 Monaco Windsor PBDD Link to comment Share on other sites More sharing options...
vito.a Posted July 26, 2021 Share Posted July 26, 2021 Glad you found it. Most of the TCM's are mounted to the main basement compartment ceiling. They are covered by the gray felt board. There should be a dedicated wire from the battery to the transmission module. I'd check the fuse in it. Link to comment Share on other sites More sharing options...

Why would they mount the TCM that far away.....lol Link to comment Share on other sites More sharing options...
dl_racing427 Posted July 27, 2021 Share Posted July 27, 2021 Mine was in the left driver's console, with the keypad mounted directly to it. 11 hours ago, Brett63 said: Mine is right on the drivers side of the transmission.

jacwjames Posted July 27, 2021 Share Posted July 27, 2021 (edited) In 2013 I lost all power to the dash and transmission control pad. I was frantic as I was getting ready to head overseas and my wife was scheduled to go to a dog show from TN to NY. Did a bunch of trouble shooting and ultimately decided it was the control module. In my case it is located in the drivers side outside electrical compartment. We live near Knoxville, where there is an Allision shop but they refused to send a mobile tech out and the coach had to be towed to the shop (~30 miles), luckily AAA covered the tow. I met the tow truck as he was coming to get it but had to head to the airport so my wire "supervised" the driver to make sure he didn't damage anything. Ultimately they found the module bad, didn't have time to wait on sending mine off for repair so a new one was $3500 installed. The had one in stock at another location and to expedite the process my wife drove ~250 miles round trip to get it. I know there are shops that rebuild for a lot less but time was not on our side. I still have the old one. Edited July 27, 2021 by jacwjames Link to comment Share on other sites More sharing options...
