6R Mechatronics Programming issues
… F150/MarK LT (6 Speed) … Expedition/Navigator (6 Speed)
I have not had this issue on the Explorers, but the same procedure may apply
Recently, I have found some issues with programming remanufactured transmissions. This procedure applies to the Mechatronics TCM found in late 2000’s Ford 6speed rear wheel drive transmission. This range of transmissions requires PMI of the PCM to initialize the TCM or Mechatronics assembly, not the entry of Solenoid strategy information.
Not all the rebuilders are "virginizing" the Mechatronics (TCM / Valvebody). This leads to a part number mismatch when performing the PCM programming. The error in FJDS would show as below:
First Delete the session
Then Navigate in Windows folder C:\ProgramData\Ford Motor Company\FJDS\Sessions and delete all of the sessions related to the vehicle that you are programming. Typically the sessions show the last 8 of the VIN and Vehicle Description. Sorting the folder by Date Modified will make it easier to isolate the related files.
Next you will need to disconnect the Transmission Bulkhead connector
Create a NEW FJDS session:
Perform the PCM PMI as installation requires:
After the PCM programming portion completes you will be prompted to “Cycle the key off then on”
After the key is turned off at this prompt, Reconnect the Transmission Bulkhead connector
Then turn the Key on
Continue Programming as normal
