• *1: Operates when OD OFF. (OD OFF indicator lamp is on.)

• *2: Oil pressure is applied to both 2nd “apply” side and 3rd “release” side of band servo piston. However, brake band does not contract

because oil pressure area on the “release” side is greater than that on the “apply” side.

• *3: Oil pressure is applied to 4th “apply” side on condition *2 above, and brake band contracts. 

• *4: A/T will not shift to 4th when OD OFF. (OD OFF indicator lamp is on.)

: Operates. 

• A: Operates when throttle opening is less than specification**, activating engine brake. 

• B: Operates during “progressive” acceleration. 

• C: Operates but does not affect power transmission.

• D: Operates when throttle opening is less than specification**, but does not affect engine brake.

- **: Overrun clutch remains in engaged condition when throttle opening is less than 1/16.

POWER TRANSMISSION

“N” and “P” Positions 

• “N” position

Power from the input shaft is not transmitted to the output shaft because the clutches do not operate.

A/T CONTROL SYSTEM

Similar to the “N” position, the clutches do not operate. The parking pawl engages with the parking gear to
mechanically hold the output shaft so that the power train is locked.

• Forward clutch
• Forward one-way clutch
• Overrun clutch
• Low & reverse brake

As overrun clutch engages, rear internal gear is locked by the operation of low and re-
verse brake.
This is different from that of D

1

 and 2

.

Engine brake

Overrun clutch always engages, therefore engine brake can be obtained when deceler-
ating.

Rear internal gear is locked to rotate counterclockwise because of the functioning of these three 
clutches.

• Forward clutch
• Forward one-way 

clutch

• Brake band

Rear sun gear drives rear planetary carrier and combined front internal gear. Front internal gear now rotates 
around front sun gear accompanying front planetary carrier.
As front planetary carrier transfers the power to rear internal gear through forward clutch and forward one-
way clutch, this rotation of rear internal gear increases the speed of rear planetary carrier compared with 
that of the 1st speed.

• High clutch
• Forward clutch
• Forward one-way 

clutch

Input power is transmitted to front planetary carrier through high clutch. And front planetary carrier is con-
nected to rear internal gear by operation of forward clutch and forward one-way clutch.
This rear internal gear rotation and another input (the rear sun gear) accompany rear planetary carrier to 
turn at the same speed.
