2014 Subaru Outback 2.5i, Standard TransSECTION Inspection
WARNING: This page is about a different variant/trim than selected.
NOTE:
When the select lever is shifted while the engine is idling, there will be a certain time elapse or lag before shock is felt. Using this, check the condition of forward brake, reverse brake, 1st one-way clutch and 3rd one-way clutch.
- Perform the test at normal operation fluid temperature of 70 - 80°C (158 - 176°F).
- Be sure to allow one minute or more interval between tests.
- Make three measurements and take the average value.
- Fully apply the parking brake.
- Start the engine. Check the idle speed. (A/C OFF)
- Shift the select lever from "N" to "D" range. Using a stop watch, measure the time-lag from shifting the lever until the shock is felt.
Time-lag
Standard: 1.2 seconds or less
If "N" → "D" time-lag is longer than specification:
- Line pressure too low
- Forward brake worn
- One-way clutch not operating properly
- In the same manner, measure the time lag of "N" → "R".
Time-lag
Standard: 1.5 seconds or less
If "N" → "R" time lag is longer than specification:
