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.

*1: Operates when overdrive control or A/T mode switch is being set in ªOFFº or ªSPORTº position.
*2: Oil pressure is applied to both 2nd ªapplyº side and 3rd ªreleaseº side of band servo piston. However, brake band does not contract because oil pressure area on the ªreleaseº side is greater than that on the ªapplyº side.
*3: Oil pressure is applied to 4th ªapplyº side in condition *2 above, and brake band contracts.
*4: A/T will not shift to 4th when overdrive control or A/T mode switch is set in ªOFFº or ªSPORTº position.
q : Operates.
: Operates when throttle opening is less than 3/16, activating engine brake.
v : Operates during ªprogressiveº acceleration.
: Operates but does not affect power transmission.
: Operates when throttle opening is less than 3/16, but does not affect engine brake.

A/T Fluid Check
FLUID LEAKAGE CHECK
1. Clean area suspected of leaking. Ð for example, mating sur-face of converter housing and transmission case.
2. Start engine, apply foot brake, place selector lever in ªDº posi- tion and wait a few minutes.
3. Stop engine.
4. Check for fresh leakage.
FLUID CONDITION CHECK
Fluid color Suspected cause
Dark or black with burned odor Wear of frictional material
Milky pink Water contamination Ð Road water enter-
ing through filler tube or breather
Varnished fluid, light to dark
brown and tacky Oxidation Ð Over or under filling, Ð Over-
heating
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.
I 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.
I During test, never hold throttle wide open for more than 5
seconds.
Stall revolution: 2,450 - 2,700 rpm
