- A manual transmission and it's related parts (linkage, clutch etc.)

- If you wish to reduce wear by a small amount you can place the

- nothing is lost. It becomes a "throwout bearing vs synchronizer"
- trade off in which the wear is measured in very small amounts and
- is an insignificant part of the total wear.
