Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello, and thank you for using Just Answer! My name is***** me a few moments to review your question and Ill do my best to assist you.
Hello, it wont reflash the TCM or it wont pass the clutch relearn process? Why are you replacing the TCM? Are you using an IDS scan tool and what level is the software you are using?
Ok, its a question of if he is having an issue with the reprogramming of the new module or if it will reprogram and pass diagnostic checks and fails running through the clutch relearn process. I would need to know these things in order to know what direction to direct you in. Also I need to know how he going about reprogramming it.
Hello, do you need more help with this concern?
Ok, this is not unusal for it to take multiple times to relearn the clutch adaptive process which is 3 steps. Relearning the transmission range sensor and the shift fork actuators. It usually times out or fails performing the last/clutch relearn. Long as it was able to reprogram the new tcm that is important. Depending on what code stored would tell more. New TCM's have been defective out of the box from ford. I have had several of them.
When there are no codes and it wont relearn, it can take several times to relearn the cluch. Most important thing is that the battery has a full charge when performing this process and the diagnostic equipment they are using is at the latest update software version.
If it is setting a code for the tcm memory failure yes.
Yes there are a few technical service bulletins out that says if the tcm pops out these codes, to replace the TCM. There is also extended warranty coverages on the tcm depending on the mileage of the vehicle.
Very good, if you need more help just let me know. If I was helpful, please leave a positive rating. I can still offer more help if needed after being rated.
You are welcome!
