According to Allison, my TCM part number is 29542725, not 29537441. My engine will not turn over and the fuse for the TCM blows when plugged in and ignition on. Bad TCM? What if I order and the the problem still exists. Can the item be returned? Will your work even though a different part number? ( mike rogers, 10/18/2016 )

Mike,

29537441 is compatible with 29542725 so it would work for you. I would recommend unplugging the TCM and then turning the ignition on to see if the fuse still blows. If it does not blow, then you have a bad TCM. 

Maybe I'm all wrong here but I would want my tranny to shift at a higher RPM. It seems my RV doesnt downshift on its own soon enough when climbing and shifts to OD too soon when on level ground. Could it be as simple as you reprogramming a TCM, sending it too me and me swapping out? Thanks ( Scott Jordan, 06/24/2016 )

Scott,

It sounds like you have the opposite problem that everyone else does. I don't think our programming is going to fix your situation. One thing that can throw the shifting all out of loop would be if the speedometer is off, you might check with a GPS to see if it is.

Is this a reconditioned unit? Is it a take out? What can you tell me about warranty? is there any. This unit I have trouble with is from 2003 Winnebago with Workhorse chassis Model 29537441 SNBKDCYFM323476152
