Toyota Corolla (E120): Manual shifting test
1. Perform manual shifting test
Hint
: by this test, it can be determined whether the trouble is within the electrical circuit or is a mechanical problem in the transaxle.

- Disconnect the transmission wire connector.
- inspect the manual driving operation.
Check that the shift and gear positions correspond to the table below.
While driving, shift through the l, 2 and d positions.
Check that the gear change corresponds to the shift position.

Hint
: if the gear positions of the l, 2 and d are difficult to distinguish, do the following road test.
