LUBRICATION AND MAINTENANCE - Maintenance ServiceO:lllO.AUTOMATIC TRANSAXLE (Inspect fluid
I~~+v~!1. Drive until the fluid temperature reaches the usual
temperature
[70-80°C (160- 18O”F)l.2. Place vehicle on level floor.
3.Move selector lever sequentially to every position to fill
torque converter and hydraulic
circuitwith fluid, then
place lever in“N” Neutral position. This operation is
necessary to be sure that fluid level check is accurate.
4.Before removing dipstick, wipe all dirt from area arounddipstick. Then take out the dipstick and check the
condition of the fluid.
The transaxle should be overhauled under the following
conditions.l If there is a “burning” odor.
l If the fluid color has become noticeably blacker.
l If there is a noticeably great amount of metal
particles in the fluid.
5.Check to see if fluid level is in “HOT” range on dipstick.If fluid level is low, add ATF until level reaches “HOT”
range.Low fluid level can cause a variety of conditions
because it allows pump to take in air along with fluid. Airtrapped in hydraulic circuit forms bubbles which make
fluid spongy. Therefore, pressures will be erratic.
Improper filling can also raise fluid level too high. Whentransaxle has too much fluid, gears churn up foam and
cause same conditions which occur with low fluid level,resulting in accelerated deterioration of ATF.
transmission fluid.
In either case, air bubbles can cause overheating, fluid
oxidation, which can interfere with normal valve, clutch,and servo operation. Foaming can also result in fluid
escaping from transaxle vent where it may be mistakenfor a leak.
6. Be sure to examine fluid on dipstick closely.lO.AUTOMATIC TRANSAXLE (Change fluid)
Drain the fluid and check whether there is any evidence of
contamination.
Replenish with new fluid after the cause of any contamina-tion has been corrected.
(1) Remove drain plugs to let fluid drain.
(2) Remove the oil pan.
(3) Check the oil filter for clogging and damage and replaceif necessary.
(4) Clean the inside of oil pan and 5 magnets.

REAR AXLE - Troubleshooting3-7
Symptom
NOTE
1 Probable cause1 Remedy
In addition to a malfunction of the differential carrier components, abnormal noise can also be caused by the universal
joint of the propeller shaft, the axle shafts, the wheel bearings, etc. Before disassembling any parts, take all
possibilities into consideration and confirm the source of the noise.

Noise from the engine, muffler vibration, transaxle, propeller shaft, wheel bearings, tires, body, etc., is easily mistaken
as being caused by malfunctions in the differential carrier components. Be extremely careful and attentive whenperforming the driving test, etc.
Test methods to confirm the source of the abnormal noise include:coasting acceleration, constant speed driving,
raising the rear wheels on a jack, etc. Use the method most appropriate to the circumstances.
