After work intended to address a manual gearbox that grinds during a shift, repeat the original conditions in a safe place and check whether the symptom returns. Note the gear and whether the sound happens on upshift, downshift, or reverse selection. Record the result before clearing codes or resetting adaptations.
Follow the maker’s procedure for drive cycles and readiness monitors. Check clutch operation and recent fluid service history; do not force the lever. If the issue remains, return to the evidence instead of swapping another part.
Quick educational note
