1. OVERVIEW

2WD

4WD

The Model 6F24 6 speed automatic transaxle is electronically controlled. The control system is 

comprised of the following components:

External transaxle control unit (TCU)

Input and output speed sensors

Six variable force solenoids(VFS) and two on/off solenoids

Torque converter

ATF temperature sensor

TCU controls the oil pressure for various internal clutches and brakes to select the gear. It also controls 

the electronic elements, shift pressure and torque converter slip. If the system is defective, TCU provides 

FMEC (Failure Mode Effect Control) to maintain the functionality of transaxle. This keeps the basic 

function of transaxle (gear selection) even when there are failure in controls and power supply.

There are selector shaft position sensor (inhibitor switch) and oil temperature sensor in transaxle. In 

manual mode, TCU receives the information from TGS (Transmission Gear Selector) through PCB 

(Printed Circuit Board) when driver selects the manual shift mode. TCU communicates with other electric 

control modules through CAN. In order to ensure a safe driving state and to prevent damage to the 

automatic transmission, TCU switches to Limp-Home mode in the event of critical faults.

2. FEATURES

1) Advantages

Early Downshift with Hard Braking and Skip Shifts

▶

When heavy braking is detected, the transaxle downshifts early and skips gears to provide increased 

engine braking to provide gear selection for tip-in.

Gear Hold going Uphill/Downhill

▶

If the accelerator pedal is released when traveling uphill, upshifts are prevented to reduce busyness on 

grades. If the accelerator pedal is released when traveling downhill, upshifts are prevented to enhance 

engine braking.

Drive and Reverse Engagement

▶

A soft engagement feature avoids harsh take up of drive when selecting Drive or Reverse. This is 

achieved by limiting engine speed and engine torque which results in a rapid, but progressive 

engagement of either Drive or Reverse when moving from the Park or Neutral positions. Drive and 

Reverse engagements from either Park or Neutral are performed in less than 2.2 seconds. There is no 

drive engagement prevention strategy implemented on the transaxle system as there is sufficient engine 

strategy to protect the system. However, reverse engagement is prevented until vehicle speed is less 

than 7 km/h.

2) Transaxle Cooling

The transaxle cooling system ensures rapid warm-up and constant operating temperature resulting in 

reduced fuel consumption and refined shift quality.

It also includes a cooler by-pass within the hydraulic system to allow sufficient lubrication to the transaxle 

drivetrain in the event of a blockage in the transaxle cooler.

3) Shift Strategy

Gear Change

▶

Transaxle gear change is controlled by the 

TCU. The TCU receives inputs from various 

engine and vehicle sensors to select shift 

schedules and to control the shift feel and 

torque converter clutch (TCC) operation at each 

gear change.

Coast down

▶

Coast down down shifts occur at 0% pedal 

when the vehicle is coasting down to a stop.

Torque Demand

▶

Torque demand down shifts occur 

(automatically) when the driver demand for 

torque is greater than the engine can provide at 

that gear ratio. If applied, the transaxle will 

disengage the TCC to provide added 

acceleration.
