Function Of Transmission Module

Control

Responsibility

Responsibility

Responsibility of this module is to get

information from sensors and runs certain

actuator that engage gears.

Sensors & Switches Linked With TCM

1- Valve Body

2- Shift Solenoid

3- Torque Converter Clutch solenoid

4- Gear Lever switch

5- Brake Pedal switch

6- Overdrive Switch

7- Power switch

Valve Body

Uses

This valve

functions as per

pressure of automatic

transmission fluid or

signal from

transmission control

module.

Shift Solenoid

Uses Of

Solenoid

This solenoid

usually controls the

flow of hydraulic

fluid for shifting gear.

The solenoid

determines the

correct up shift &

down shift points

for all driving

conditions.

Torque Converter Clutch

Solenoid

Torque Converter Clutch

Solenoid

UsesThis solenoid

controls the fluid

entering & exiting

the torque

converter clutch.

It is fixed in valve

body.

Gear Lever Switch

It gives signal to which

mode to drive the

vehicle.

When you are in

adventurous driving

then open the switch &

use electrical contact

cleaner.

Uses

Brake Pedal Switch

This switch is a on/off switch located in front of brake

pedal. The switch gives signal when brake is pressed or

released.

The transmission converter clutch disengages when

brake is applied & engages when brake is released.

Uses

Overdrive Switch

When you want acceleration power then you can

use the overdrive switch.

It can be used when slow down without immediate

stepping on brakes or adding braking power through

engine.

Uses

Power/Sports Switch

Power/Sports Switch

Programming of automatic transmission is

changed by power button.

In power mode automatic transmission will

hold gears in a long time during take off &

acceleration.

Sometimes

solenoid

switches are

not working

properly so

create problem

for driving.

If getting any

problem in solenoid

switch then

immediately change

or repair for better

driving.
