Diagnostic Tests: Notes
WARNING: This page is about a different car, the 2000 Toyota Land Cruiser and 2000 Lexus LX 470. However, it is still accessible from the selected car via links, so may be relevant.
When trouble shooting transmission, first check for stored DTCs and repair as necessary. If no DTCs exist, perform manual shift test to determine if problem area is in electrical circuits or a mechanical transmission problem. See MANUAL SHIFT TEST under DIAGNOSIS & TESTING.
