A few seconds of check-ball footage can't diagnose a shifting problem on its own. Pair this with the full transmission video for the broader job.

A closer look at this job

This BMW G6L45R/GA6L45R Short concerns valve-body check-ball wear, a specific internal transmission component rather than a general transmission rebuild. Relevant terms include valve body, check-ball seat, mechatronic assembly and 6L45 shift behavior, but individual symptoms or test results should not be inferred from this short clip. Follow the companion BMW automatic-transmission shift-repair video to see the larger work. Identify the actual 6L45-family variant before comparing parts or procedures.
