How to Install Manual Transmission in the Car Equipped with the Automatic Transmission
Failure of the automatic transmission often turns out to be the case when car owners decide to replace the broken automatic transmission with the less expensive manual transmission. In this article we will consider the implementation of this procedure and how to do it by yourself.
The decision to replace the automatic transmission with the manual transmission solution can also be caused by operational properties of the manual gearbox: this type of transmission has better acceleration dynamics as well as enhanced fuel efficiency. The manual transmission installation process is specific for each car, but generally, the set of required parts and applied technologies are very similar.
Parts required for installation of the manual transmission
When installing the manual transmission it is necessary to have the following parts at your disposal (these parts may be used as well as new):
- Manual gearbox
- Clutch kit
- Flywheel
- Gear shifter
- Detent cables
- Clutch pedal
- Both clutch cylinders (master and working/slave)
- Engine control unit (ECU) for manual transmission
- Engine support cushions
Automatic transmission removal
When you have all required spare parts, it is time to start the transmission replacement operation. First of all, it is necessary to lift up the front part of the car, then engine and transmission protection units should be removed. Depending on the car interior design, it is also necessary to dismantle the car dashboard. After removing terminals from the accumulator, you have to disconnect the starter ( if it is located under the powertrain).

The next step is to disconnect the lines
directly connected to the automatic transmission.
The step-by-step guide is the following:
- Disconnect wiring harness from the transmission housing
- Disengage the lever cable which is responsible for gear shifting operations and speed sensor
- Dismount radiator pipes of the automatic transmission cooling system and drain ATF.
After that, the engine must be fixedly attached to prevent falling. The automatic transmission should be disconnected in the following way: unscrew fastening bolts which help to attach the transmission to the engine, unscrew the transmission support, brackets, intermediate shaft, and torque converter. After the automatic transmission is dismantled with the help of the lifting jack, it is time to install all parts required for proper operation of the manual transmission.
Manual transmission installation
The manual transmission installation
process starts with mounting of the flywheel and detent cables of the manual
transmission. Then, it is necessary to replace the automatic transmission gear
shifter with the manual shifter. Clutch and brake pedals should be installed in
the car interior, while clutch cylinders should be integrated in the hydraulic
system of the car. The manual transmission is mounted with the help of bolts.
In addition, it is necessary to install air conduits and replace the engine
ECU. The manual transmission is completed by attaching the accumulator
terminals.
