Hello
I have a 2005 P42 Workhorse step van that is blowing the TCM BATT fuse whenever the TCM is plugged in and the battery is connected. It has a Cummins ISB 170 3.9L diesel motor and an Allison 1000 transmission. The TCM number is W0005263. Will this computer work for my application or do you have one that will?
Thanks

We do not have the software to use for your engine combination. I would recommend going to an Allison Dealer for this particular vehicle. They would need the information off the tag on the TCM to get you a replacement.
transmission will shift in forward and reverse . Drive goes 40 mph. the gear inditcator in dash does not move stays in drive no matter what gear selector is in ( ron duvall, 03/22/2019 )

It could be an issue with the TCM but it almost sounds like it could be a problem with the mode selector on the side of the transmission. I would start there before changing out the TCM.

Is this transmission controller legal for CARB (California) regulations?? And is the engine controller legal for California also?? Do you charge for installation of either is I come to your shop?? Thanks, Alan Utzig ( Alan Utzig, 03/07/2019 )
We do not have CARB certifications for these products. If the vehicle is brought to us, we do not charge labor as we can change the programming via the OBD2 port.
what kind of vehicle this part goes on

This controller is used on a wide range of vehicles but we only can program them for use in the Workhorse Chassis. From your VIN it looks like you have a Freightliner chassis so you will need to contact a Freightliner dealer for help with this.
Hello, I’m thinking of purchasing a 2007 workhorse with 26k Miles but it seems to be having a problem shifting into gear. The procedure to get it to drive is.. Start engine Put into drive Put back into park Shut off engine Start engine Put into drive Then it will go into gear. Reasearch ive done comes back to a TCM problem. How should I remedy?
