6R140 FAQ’s
Q: Do I need to update my TCM before driving?
Yes. When you receive your transmission, you will get a tag with a “Strategy Code”. This code must be calibrated into your TCM to ensure proper shifting. This must be performed with a ‘Forscan’ Scantool. Your local dealer will be able to perform this; as well as some mechanic shops. Scantools, EzLynk, and other third party OBD tools can not perform this function.
