Shift Mechanism
The automatic transmission uses compact, dual planetary gear systems to improve power-transmission
efficiency, simplify construction and reduce weight.
It also employs an optimum shift control and superwide gear ratios. They improve starting performance and
acceleration during medium and high-speed operation.
Two one-way clutches are also employed: one is used for the forward clutch and the other for the low clutch.
These one-way clutches, combined with four accumulators, reduce shifting shock to a minimum.

A/T Fluid Check
FLUID LEAKAGE CHECK
1. Clean area suspected of leaking. Ð for example, mating
surface of converter housing and transmission case.
2. Start engine, apply foot brake, place selector lever in ªDº
position and wait a few minutes.
3. Stop engine.
4. Check for fresh leakage.
FLUID CONDITION CHECK
Fluid color Suspected problem
Dark or black with burned odor Wear of frictional material
Milky pinkWater contamination Ð Road water
entering through filler tube or breather
Varnished fluid, light to dark brown
and tackyOxidation Ð Over or under filling, Ð
Overheating
FLUID LEVEL CHECK
Refer to MA section (ªChecking A/T Fluidº, ªCHASSIS AND
BODY MAINTENANCEº).
Stall Test
STALL TEST PROCEDURE
1. Check A/T and engine fluid levels. If necessary, add.
2. Drive vehicle for approx. 10 minutes or until engine oil and
ATF reach operating temperature.
ATF operating temperature:
50 - 80ÉC (122 - 176ÉF)
3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during
test.
+It is good practice to put a mark on point of specified
engine rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in ªDº
position.
6. Accelerate to wide open throttle gradually while applying foot
brake.
7. Quickly note the engine stall revolution and immediately
release throttle.
+During test, never hold throttle wide open for more than
5 seconds.
Stall revolution:
2,480 - 2,680 rpm
