SOURCE: replace transmission control module?

You should really have a qualified tech. replace this control unit. It is located in the foot well in passenger side. There is a false floor held in by 10mm nuts that the unit attaches to. You will more than likely need a S.D.S. machine to download the software out of the old unit and into the new unit. Next you will have to version code the new unit and set the parameters for your shift points. I have never replaced one and tried to start and drive the vehicle w/o the S.D.S.. I can't be sure it would be drivable but there is only one way to find out. Either way you will have to take to appropriate repair facility and won't have the same warranty replacing it yourself. What ever you do do not remove the electrical connector with the key on, I also hope that the vehicle was properly diagnosed. Hopefully I have been helpful. Good luck

2004 dodge sprinter trans stuck in low gear . i am trying to locate the trans module

Check under seat unplug control module see if it is wet with fluid . cost me $138.00 fee.
Engine light on than next day off may 2 day then on at same place drive kid to school.
issue with transmission fluid wicking up the harness into the control module and causing the module to malfunction. Usually, the harness from the transmission to the ETC module is replaced and the module is replaced provided the leak is repaired. In some cases this may be more than is actually needed but it usually fixes the concern. Transmission fluid does not actually damage the module and can be flushed away with board cleaning solvent or electrical contact cleaner as a first attempt. Always repair the leak before replacing a module.
