DISASSEMBLY
Caution1. The automatic transaxle consists of high-precision
parts and utmost care must be exercised during
disassembly and reassembly to prevent damage to the
parts.
2.Place a rubber mat on the workbench and keep it cleanat all times.
3.Do not use cotton work gloves or waste cloth for the
disassembly job. Use nylon cloth or paper towel if
necessary.4. Clean all disassembled parts. Commercially available
detergent may be used to clean the
metalllic parts;
however, be sure to dry them completely with air.
5. Clean the clutch disc, plastic thrust plates, and rubberparts with ATF (automatic transmission fluid) to pre-
vent adhesion of dust and dirt.
6.If the transaxle is damaged, the cooler system should
also be disassembled and cleaned.(1) Remove the torque converter.
(2) Install the dial indicator to the transaxle case and measure
the end play in the input shaft.
(3) Remove brackets.
(4) Remove the oil level gauge and oil level gauge guide.
(5) Remove pulse generators A and B
(6) Remove the manual control lever and then remove the
inhibitor switch.
(7) Remove the speedometer drive gear assembly.
