(1) Prior to disassembling the transaxle, openings
and thoroughly clean the exterior of the, assembly, prefer-
ably by steam.
(2) Place the transmission on the ‘workbench with t he oil
pan down.
(3) Remove the torque converter.
.
(4)Measuring input shaft end play will
usually indicate when a thrust is required
(except when major parts are replaced). Thrust wash ers
are located between the shaft support and rear
clutch retainer, and between the reaction shaft sup port
and front clutch ‘retainer.
Mount a dial indicator to the converter housing usi ng
the special tool, with its plunger seated against t he end
of the input shaft.
Move the input shaft in and out with pliers to obta in the
end play reading. Be careful not to scratch the inp ut shaft.
Record the indicator reading for reference when rea ssem-
bling the transaxle.
(5) Remove pulse generators “A” and “B”.
(6) Remove the manual control lever, and then remov e
park/neutral position switch. ,
