Part Name

Function

Forward clutch

Meshes input shaft and intermediate shaft.

Direct clutch

Meshes input shaft and MD planetary carrier.

Reverse clutch

Meshes input shaft and FR sun gear.

No.1 brake

Fixes FR planetary carrier.

No.2 brake

Fixes FR and MD ring gear.

2nd brake

Fixes outer race of one-way No.2 clutch, to prevent FR sun gear from turning 
counterclockwise (reverse direction of engine input rotation direction).

1st and reverse brake

Fixes RR ring gear.

One-way No.1

Prevent FR planetary carrier from turning counterclockwise.

One-way No.2

Prevent FR sun gear from turning counterclockwise only when 2nd brake is at work.

One-way No.3

Prevent RR ring gear from turning counterclockwise.

Automatic Gear Shift Table

S6JB0B5101010

Automatic gear shift schedule is shown in the following table. Test-drive the vehicle on a flat road in the D position.

1. Shift Point in D position and transfer shift position in 4H

2. TCC lock-up point in D position and/or 4 position mode

NOTE
The gear change is done at the shift point different from the above while any of the following control 
functions is working. Bear this in mind when performing inspection.

 

• Slope Shift Control

When TCM makes up-slope judgment, Slope Shift Control (on up-slope) is executed by changing the gear change 
point to the high-speed side so as to reduce frequent up-shift and down-shift operations.
When TCM makes down-shift judgment, Slope Shift Control (on down-slope) is executed by changing the gear 
change point to the low-speed side so as to use engine-brake function effectively while driving on a down-slope.

• Cruise Shift Control

Cruise Shift Control is executed by selecting appropriate gear according to requirement for retaining a constant 
vehicle speed or acceleration so as to reduce frequent up-shift and down-shift operations while cruising.
