Disabling the electronic automatic transmission control unit (automatic transmission ECU) will lead to the following consequences:
*Gearbox will not work:
* The car will not be able to move.
* Changing gears will become impossible.
* Loss of gearbox control:
* There will be no ability to manually change gears or select transmission modes.
* The engine management system will not be able to adjust the engine speed according to the transmission position.
* Disabling cruise control mode:
* If the vehicle is equipped with cruise control, it will be disabled due to lack of signal from the automatic transmission ECU.
* Loss of information about the state of the automatic transmission:
* The dashboard will not display information about the gear engaged, engine speed and other automatic transmission parameters.
*Damage to gearbox:
* If the automatic transmission ECU is faulty and cannot control the transmission properly, it may cause damage to automatic transmission components such as gears, clutches, etc.
Note:
Disabling the automatic transmission ECU is generally not recommended and should only be performed by a qualified automotive technician. This is usually only done in the event of a serious ECU failure or for diagnostic purposes.
