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.
