AUTOMATIC, TRANSAXLE ASSEMBLY
DISASSEMBLY
Caution
Because the automatic transaxle is composed of component
parts of an especially high degree of precision, these parts
should be very carefully handled during disassembly and
assembly so as not to scar or scratch them.
A rubber mat should be placed on the workbench, and it
should always be kept clean.
During disassembly, cloth gloves or rags should not be used.
If such items must be used, use articles made of nylon, or use
paper towels.
All disassembled parts must be thoroughly cleaned. Metal
parts may be cleaned with ordinary detergents, bet must be
thoroughly air dried.
Clean the clutch disc, resin thrust plate and rubber parts by
using ATF (automatic transmission fluid), being very careful
that dust, dirt, etc. do not adhere.
If the transaxle main unit is damaged, also disassemble and
clean the cooler system.
1. Clean away any sand, mud, etc. adhered around the
transaxle.
2. Place the transaxle assembly on the workbench with the oil
pan down.
3. Remove the torque converter.
4. Measuring input shaft end play before disassembly will
usually indicate when a thrust washer change is required
(except when major parts are replaced). Thrust washers are
located between reaction shaft support and rear clutch
retainer, and between reaction shaft support and front clutch
retainer.
Mount a dial indicator to converter housing with the Dial
Indicator Support Make sure that the indicator plunger is
seated against end of input shaft.
When checking end play, pull out or push in the input shaft
with pliers. Be careful not to scratch the input shaft. Record
indicator reading for reference when reassembling transaxle.
