Allison 5 speed tcm needed
« on: September 20, 2018, 07:42:42 PM »
I have a 2004 Monaco Cayman with Cummins ISB-300 engine and Allison 2000MH transmission. The controller is fried due to incorrect battery polarity hookup. (No lights on keypad.) Power is getting to both TCM and keypad. I need a replacement TCM. The model is 29537441 and the label says "2800 rpm" and "Throttle J-1989" and "5421-L". I've xhecked with several TCM rebuild places and they say they do not work on these. Can anyone out there advise me as to where I can get a replacement? Thanks.

Even Ebay has them.

UltraRV Products is another excellent source for anything related to a Workhorse chassis. They have rebuilt TCMs.
