SERVICE INFORMATION
If an R30A transmission exhibits a whine noise while driving in all forward gears except 4th which is more pronounced at slow speeds, the incident may
be caused by lack of lubrication to the main and counter drive gears. This noise may occur particularly on acceleration and/or climbing hills.
A countermeasure transmission case is available to resolve this incident.
SERVICE PROCEDURE
1. Verify the incident occurs under the driving conditions described above.
2. If the noise is verified, disassemble the transmission.
3. Replace the counter and main gears with new parts. Refer to the parts catalog.
4. Install a countermeasure transmission case, P/N 32101-01G11 (former P/N 32101-01G10). When installing the transmission case, note the
following changes to the transmission case and fluid levels:
-
The transmission oil level has been increased from 3.6 ± 0.1 L to 5.1 ± 0.1 L (an increase of 1.5 L) to prevent lack of lubrication.
