Bench Work Warranty & Installation Policy

 

At OS Transmissions, we stand behind the quality of our bench work transmission rebuilds. Bench Work refers to transmissions that are removed, delivered, and reinstalled by a third-party shop or individual.

Because OS Transmissions does not perform removal or installation in bench work services, we cannot assume liability for installation procedures, vehicle condition, or any resulting external system failures.

This policy applies strictly to transmission units rebuilt by OS Transmissions under bench work service.

  • Internal components of the rebuilt transmission
  • Workmanship related to disassembly, inspection, and rebuild procedures
  • Internal failure directly related to the rebuild process

❌ Warranty Does NOT Cover:

  • Torque converter installation errors
  • External electrical issues or wiring faults

  • Incorrect fluid type or fluid level
  • Labor costs for removal or reinstallation
