Why lock washers matter
A lock washer keeps a fastener tight when the vehicle vibrates, which is constant on a transmission and the parts around it. At the shift rail support plate, the washer helps the plate stay put so the shifter does not drift out of alignment. Lock washers work by spring tension, so a flattened or distorted one loses its grip.
Before reinstalling, clean the bolt threads and the seat where the washer contacts the plate. Look for corrosion, nicks, or a bent edge, and replace any part that does not seat flat. Tighten the fastener to the level in your service manual, since the washer is only one part of a secure joint.
- Inspect the washer for flattening or bent edges
- Clean the bolt threads before reassembly
- Seat the washer flat against the plate
