Hi guys so I changed my transmission sensor but my check engine light still comes on. The Indy shop I took it to did the adaptive reset without a GDS or HI Scan pro. They do not have one. Closest dealer is far. Does anyone have any idea if resetting it with these tools is mandatory, it says the GDS is required to reset all cars starting with the year 2005 on the tsb's Are all other tools useless? Did anyone's CEL come on when they didn't use the GDS to reset.
