NOTICE:

When the manual transaxle assembly is removed, be sure to use a new clutch release cylinder with bearing assembly and new installation bolts. Removal of the manual transaxle assembly allows the compressed clutch release cylinder with bearing assembly to return to its original position. Dust from the moving section may damage the seal of the clutch release cylinder with bearing assembly, possibly causing clutch fluid leaks.

HINT:

When the cable is disconnected / reconnected to the auxiliary battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.
