The document outlines the responsibilities and functions of the transmission module control, including its interaction with various sensors and solenoids like the valve body, shift solenoid, and torque converter clutch solenoid. It explains the roles of switches such as the gear lever, brake pedal, overdrive, and power/sports switch in managing gear shifts and vehicle performance. It emphasizes the importance of maintaining functioning solenoid switches to ensure smooth driving.

1. Transmission Module Control

2. Function Of Transmission Module
Control
Responsibility

3. Responsibility
 Responsibility of this module is to get
information from sensors and runs certain
actuator that engage gears.

4. 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

5. Valve Body

6. Uses
 This valve
functions as per
pressure of automatic
transmission fluid or
signal from
transmission control
module.

7. Shift Solenoid

8. 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.

9. Torque Converter Clutch
Solenoid

10. Torque Converter Clutch
Solenoid
UsesThis solenoid
controls the fluid
entering & exiting
the torque
converter clutch.
It is fixed in valve
body.

11. Gear Lever Switch

12. 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

13. Brake Pedal Switch

14. 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

15. Overdrive Switch

16.  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

17. Power/Sports Switch

18. 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.

19.  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.
