Why does the JAC T6 transmission overheat o r feel excessively hot during prolonged use?

A number of owners have reported that the transmission gets very hot after long drives o r heavy load conditions, sometimes accompanied by a burning smell o r temporary loss of smooth shifting. What are the typical reasons for transmission overheating in the JAC T6 — such as fluid degradation, poor cooling, o r mechanical wear — and what preventive steps can be taken to maintain transmission health?

Transmission overheating in the JAC T6 is usually caused by fluid degradation, heavy loads, o r mechanical strain:

Low o r degraded transmission fluid: Old fluid loses its heat‑dissipating and lubricating properties, causing temperature rise.

Heavy o r continuous load: Carrying full cargo on long drives generates more heat due to increased friction inside the transmission.

Mechanical wear: Worn bearings, gears, o r clutch components create excess friction, producing heat.

Insufficient cooling if applicable: Some vehicles rely on airflow o r auxiliary cooling obstruction o r failure can increase temperatures.

Preventive measures:

Monitor and replace transmission fluid at recommended intervals.

Avoid extended operation at full load without breaks.

Address any abnormal noises o r resistance promptly to prevent heat buildup and component damage.
