TRANSAXLE CASE
Inspection
Inspect case for cracks and stripped threads. Inspect gasket surfaces and mating surfaces for burrs. Check vent for obstructions, and check all
fluid passages for obstructions and leakage. Inspect case bushing for scores. Check all parking linkage parts for wear or damage.
TRANSAXLE REASSEMBLY
OUTPUT SHAFT BEARING PRELOAD
1. Position output shaft into torque converter housing. Position output shaft outer bearing race in recessed end of Gauge Tool (T87C-
770002DJ). Place gauge tool over output shaft. See Fig. 24
.
2. Ensure gauge tool is completely threaded together so that no gap is present. Position spacer collars and assemble output bearing and
idler support to converter housing using supplied bolts and washers of tool set. See Fig. 24
. Tighten bolts to 14-19 ft. lbs. (26 N.m).
NOTE:Handle all parts carefully to avoid dam aging bearings and m ating surfaces. Lubricate all parts with
clean AT F. Use petroleum jelly on gaskets, thrust washers and needle bearings to retain them in place.
Soak all friction discs in AT F for at least 15 m inutes. Use all new gaskets and seals, and tighten bolts
evenly.
NOTE:For identification and position of thrust bearings and washers, see Fig. 27

AUTOMATIC TRANSMISSION APPLICATIONS
LUBRICATION
SERVICE INTERVALS
Check fluid level at every engine oil change. Fluid, filter changes and band adjustments are not required under normal operation. Under severe
service operating conditions, change fluid every 30 months or 30,000 miles. Adjust band when fluid is changed.
CHECKING FLUID LEVEL
With transmission at normal operating temperature, place vehicle on level surface. Apply parking brake and run engine at idle. Run gearshift
lever through all positions, ending in Park. With engine running, fluid level should be between "F" and "L" marks. DO NOT overfill.
RECOMMENDED FLUID
Use Dexron-II ATF.
FLUID CAPACITIES
TRANSMISSION REFILL CAPACITIES
DRAINING & REFILLING
1. Remove undercover and side cover to gain access to transaxle oil pan. Remove drain plug and drain fluid. Remove oil pan and discard
gasket. Clean or replace filter screen as necessary. Tighten screen bolts to 71-97 INCH lbs. (8-11 N.m).
2. Install oil pan bolts. Tighten bolts to 44-71 INCH lbs. (5-8 N.m). On all models, install drain plug with NEW washer. Tighten plug to
29-40 ft. lbs. (39-54 N.m).
3. Install undercover and side cover. Add about 3 qts. of specified ATF through dipstick guide tube. DO NOT overfill. Run engine to
normal operating temperature and check fluid level.
ADJUSTMENTS
NEUTRAL SAFETY SWITCH
Combination neutral safety and back-up light switch is screwed into transaxle case. No adjustments are necessary.
SHIFT CONTROL CABLE
