INSPECTION

Note

If the select lever is shifted while the engine is idling, there will be a certain time elapse or lag before the shock can be felt. This is used for checking the condition of the low clutch, reverse clutch, low & reverse brake and one-way clutch.

• Perform the test at normal operating fluid temperature 70 to 80°C (158 to 176°F).

• Be sure to allow a 1 minute interval between tests.

• Make three measurements and take the average value.


Fully apply the parking brake.

Start the engine.

Check the idling speed (A/C OFF).

Shift the select lever from “N” to “D” range.

Using a stop watch, measure the time it takes from shifting the lever until the shock is felt.

Time lag: Less than 1.2 seconds

If “N” → “D” time lag is longer than specified:


• Line pressure too low

• Low clutch worn

• One-way clutch not operating properly

• D-ring worn


In the same manner, measure the time lag for “N” → “R”.

Time lag: Less than 1.5 seconds

If “N” → “R” time lag is longer than specified:


• Line pressure too low

• Reverse clutch worn

• Low & reverse brake worn

• D-ring worn
