- Raise and safely support vehicle.
CA U JIOG
Male sure the car is stable and well supported at all times.
Use a professional automotive lift
orjack stands designed for
the purpose. A floorjack is not adequate support
4 With engine running and selector lever in PARK, remove filler
plug (arrow)
(A5S 360R transmission shown, refer to other
illustrations for location of filler and drain plugs on other
transmissions).
If a small stream of fluid runs out of the filler hole the level
is correct.
If no fluid
leaks out when plug is removed, fluid level is to
low. Add ATF fluid until it starts to overflow.
Install filler plug using a new sealing ring.
Hot ATF can scald. Wear eye protection and protective cloth-
ing andgloves during
the check. If the tmnsmission was over-
filled, hot ATF will spill from the filler hole when the
fill plug is
removed.
ATF, draining and filling
The procedure given here includes removal and installation of
the fluid strainer (filter). Refer to illustrations in Automatic
transmission fluid
pan and strainer.
Remove ATF drain plug
(1) and drain fluid into container.
WARNING-
ATFshould be warm when draining. Hot ATFcan scald. Wear
eye protection, protective clothing and gloves.
Remove transmission pan mounting bolts and remove pan.
Remove pan gasket and clean
gasket sealing surface.
- Pull ATF strainer from transmission pump housing. If strainer
sealing ring remains in pump housing remove using a seal
puller.
- Installation is reverse of removal.
Always replace seal for drain plug and all
gasket(s)
and O-rings.
Clean sump and sump
magnet(s) using a lint-free cloth.
Tighten transmission pan bolts in sequential order.

Reinstall driveshafl using new nuts.
Install new sealing washers on transmission cooling line
banjo bolts.
Install new O-rings on transmission cooler lines, where
applicable.
Inspect engine drive plate (flywheel) for cracks or elongat-
ed holes. Replace
if necessary.
Be sure bellhousing alignment dowel sleeves are located
correctly. Replace damaged sleeves.
Checlc to be sure torque converter is seated correctly in

This repair group covers transmission gearshift and linkage service for both manual and automatic transmission
equipped vehicles.
To gain access to the complete gearshift mechanism it is
necessary to remove the exhaust system and the driveshaft
as described in
180 Exhaust System and 260 Driveshaft.
NOTE-
In models with automatic transmission, the electronic immo-
bilizer
(EWS) prevents starter operation unless the gear po-
sition is Park or Neutral.
