Figure 1 - HM-282 Transaxle Identification Information RPO MG1/MG2:
Some early 1988 models listed above, equipped with a HM-282 manual transaxle (RPO MG1 and MG2), may experience a fluid leak from the indicator bore (refer Figure 1).
An updated design fluid level indicator assembly is estimated to be used in production November, 1987.
If this condition is encountered, try to pull out the indicator (with the cam-lock on). If the indicator pulls out install the updated design fluid level indicator assembly (estimated availability for service December, 1987). The updated design has four grooves in the plug to help "grab" on the bore. The new indicator will also have an expanded "OK" fluid level section that is crosshatched.
Figure 2 - Fluid Level Indicator Assembly And Bore:
If the updated design indicator is not available then the fluid level indicator bore will have to be "roughed" up so the plug of the old design will "grab" on the bore. To service, perform the following procedure (refer Figure 2).
1. Release the cam-lock then remove fluid level indicator assembly.
2. wipe indicator bore with Synchromesh Transmission Fluid (STF).
3. Put a new battery terminal brush (15 mm (5/8 in.) minimum diameter) into the bore and rotate at least eight complete turns.
NOTE: Use a NEW battery terminal brush--a used brush can leave corrosion and other foreign matter inside the transaxle.
4. Remove battery terminal brush and clean bore with a clean cloth.
5. Install fluid level indicator assembly.
6. Check for proper fit by trying to pull out the indicator with the indicator cam-lock on.
- If the indicator can be pulled out, repeat the above procedure.
