NOTE: Buildup of contamination can block the flow of lubricant behind the cup plug and cause transmission assembly damage.

Inspect the output shaft for damage. If damage is found, install a new shaft.
- Inspect the output shaft.
- Inspect the park and Output Shaft Speed (OSS) sensor gear.
- Inspect the bearing surfaces of the output shaft for wear or scores. If excessive wear or scoring is found, install a new output shaft and inspect the mating components.
- Check the splines on the output shaft for wear. Install a new output shaft if the splines are excessively worn. Inspect all the bushings for wear. Install a new output shaft if worn or damaged.
