DISASSEMBLY

CAUTION

• Because the automatic transaxle is manufactured from 

high-precision parts, care must be taken not to scratch 
or damage these parts during disassembly and assem-
bly.

• The working area should be covered with a rubber mat 

to keep it clean at all times.

• Do not wear any cloth gloves and do not use any shop 

towels during disassembly. Use only nylon cloth, paper 
towels or any other lint-free material.

• Parts which have been disassembled should all be 

cleaned. Metal parts can be cleaned with normal deter-
gent, but they should be dried completely using com-
pressed air.

• Clutch discs, plastic thrust plates and rubber parts 

should be cleaned with automatic transmission fluid 
(ATF).

• If the transaxle body has been damaged, disassemble 

and clean the cooler system.
