Transmission preparation:

1. Clean exterior of transmission gasoline works best or brake parts cleaner
2. Clean transmission bell housing
3. Undo throw out bearing retention spring
4. Remove old throw out bearing
5. Remove release fork and throw out bearing retention spring
6. Clean release fork and throw out bearing retention spring
7. Clean input shaft of the transmission
8. Grease input shaft
9. Grease tips of release fork
10. Install new throw out bearing, throw out bearing retention spring, and release fork
11. If you have received the S20 transmission with the D16Z6 then remove the back up switch and put it in the L3 transmission as it will be able to plug into the wiring harness correctly. Otherwise you can splice the wires of the L3 back up switch to the wires of the D16Z6 wiring harness you will know which connector it is because it won’t have anywhere to plug into one everything is plugged in. You could also get a S20 back up switch from the junkyard like I did if you don’t have the S20 transmission to steal it from and still want the cleaner install.

 This step should take you no more than 30 minutes with hand tools
