On my wife's 03 KJ the Check Engine light came on today and her transmission went into 'limp' mode. I have a good friend who runs a diagnostic business and he pulled the Code
P0605 - Internal Transmissin Control Module (TCM)
Can anyone tell me if this could be under recall? Her KJ has 103K miles so it definitely is OUT of warranty. My friend is looking at some of his online suppliers but he was thinking this was possibly a dealer item only and that they'd have to reprogram it after installation.
Any suggestions or help is much appreciated.
