Installation & Technical Notes
Fluid Service: Upon installation, we strongly recommend filling the transmission with genuine Toyota ATF Type T-IV fluid. Using the correct fluid is crucial for maintaining proper hydraulic pressure and preventing valve body sludge build-up.
TCU Check: Since this is a computer-controlled transmission, ensure your existing Transmission Control Unit (TCU) is functioning correctly. If you were experiencing “limp mode” or erratic shifting prior to failure, verify that your wiring harness is free of corrosion before mating it to the new unit.
Mounting Points: Before final torque-down, inspect your transmission mounts. Replacing worn rubber mounts with fresh ones will eliminate vibrations and significantly extend the life of your new transmission’s internal seals.
Safety First: Always use professional-grade jack stands or a lift. Ensure the engine is supported securely via an engine brace or stand before unbolting the transmission bellhousing.
