Possible reasons for automatic transmission overheating when the engine overheats:
1. Malfunction of the engine cooling system:
* Coolant leak
* Faulty thermostat
* Clogged radiator
2. Automatic transmission system malfunction:
*Low transmission fluid level
* Contaminated transmission fluid
* Faulty oil pump
* Clogged automatic transmission filter
3. High load on the engine and transmission:
* Towing heavy load
* Driving on steep slopes
* Aggressive driving with fast acceleration and deceleration
4. Mechanical faults:
* Slipping of clutches or brake bands in automatic transmissions
* Malfunctions in the torque converter
How it happens:
When the engine overheats, excessive heat can be transferred to the transmission fluid through the heat exchanger located in the engine radiator. This can lead to overheating and degradation of the transmission fluid, causing damage to the internal components of the automatic transmission.
Consequences of automatic transmission overheating:
* Accelerated wear of automatic transmission components
* Gear slippage
* Difficulty shifting gears
* Complete breakdown of the automatic transmission
Troubleshooting:
To eliminate the problem of automatic transmission overheating, you must:
* Identify and eliminate the cause of engine overheating
* Check the level and condition of the transmission fluid
* If necessary, replace the transmission fluid and filter
* Check the functionality of the automatic transmission cooling system
* Inspect the mechanical components of the automatic transmission for faults
