DESCRIPTION
Transmission system is a important part for car, so a well maintain transmission system always give a better driving for a user.TRANSCRIPT
Transmission Module Control
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.
