Operation CHARM: Car repair manuals for everyone.

Initial Inspection and Diagnostic Overview

CAUTION:
^ An automatic transmission should not be exchanged or reconditioned before a thorough troubleshooting has been carried out.

^ Fault symptoms can sometimes be misleading, for instance if an oil passage is blocked by clutch particles as a result of the clutch slipping, the removal of the blockage will only postpone transmission breakdown and not stop it.

^ It is therefore important to check the condition of the oil; if the strainer is blocked, particles in the sump, etc.

^ In this way it will be possible at an early stage to establish where the actual fault is.
