Overview
This is a hands-on, in-cab walkthrough of recalibrating the gearbox on a Case IH MXM155, filmed while the presenter actually performs the procedure: warming the transmission with a 15-20 minute drive, then stepping through the button sequence (hold up/down buttons, cycle through ranges A through E) to recalibrate shift points. He also notes the process differs slightly for TM-series gearsticks. Useful for MXM/TM owners troubleshooting jumpy or slipping gear shifts.
Posted by the Michael Clavin channel, apparently an owner or operator sharing a practical maintenance procedure filmed on a phone rather than a polished production.
