The transmission control module may only need what is called “shift quality quick-lean procedure” performed.
This would mean; connecting a scan tool that had the capability of entering and performing this function?
NOT A CODE READER; THAT’S ALL A READER CAN DO IS READ ENGINE MANAGEMENT ONLY CODES? IT IS NOT A SCAN TOOL!
Sorry for yelling but so many people seem to think their 50 or whatever dollar reader will do or is the same thing as what a 10 to 15,000 dollar scanner is and does.
Yes a reader can retrieve SOME codes but a proper scanner will allow you to monitor data from all systems (Power train, body-control and chassis), perform and receive by-directional commands along with the basic code retrieval. OK enough of that LOL
This part of your post confuses me (not hard to do).
Now it's stuck in first gear. Shifter wwont move with key off, reverse, neutral and park where they should be.
Do you mean you cannot physically move the gear shifter from the first gear position? If so then you may have a mechanical issue; with the shifter assembly, cable or the mechanisms inside the trans?
