Transmission overheating causes

Transmission especially the automatics can overheat. The causes range from bad clutch, wrong fluid, overfilled or underfilled transmission and bad oil cooler.

REASONS WHY AUTOMATIC TRANSMISSIONS OVERHEAT

Overheating is a major killer of automatic transmissions especially when the overheating is not caught on time.

THE FOLLOWING ARE VARIOUS COMMON ISSUES THAT CAUSE AUTOMATIC TRANSMISSIONS TO OVERHEAT.

Fluid leak - When the automatic transmission fluid is low due to leakage, there won't be enough fluid to circulate and dissipate the heat thereby causing transmission overheat.

Low fluid - Low transmission fluid level can be as a result of fluid leakage or incorrect fill level when the transmission was filled.

Degraded fluid - A worn out transmission fluid would not be able to lubricate parts properly thereby causing overheating as the friction of the moving parts increases.

Wrong or low quality transmission fluid - A wrong fluid can cause slippage of clutches. When clutches slip, they generate a lot of heat. Low quality fluids lubricates less and are susceptible to oxidation more than quality transmission fluids. Synthetic oils are better than mineral oils.

Worn clutches and bands/brakes - when these parts have worn out, they cause slipping which generates excessive heat.

Faulty solenoid - Faulty solenoid can cause wrong application of fluid pressure that can lead to slippage of clutches followed by overheating.

Hot weather - Ambient temperature can raise the internal temperature of transmissions especially those type of transmissions that do not have a transmission cooler or heat exchanger.

Driving habit/condition - A transmission can overheat when it is subjected to severe driving condition like harsh driving, prolonged stop and go driving and driving in terrible off-road terrain.

Faulty torque converter lock-up system - Torque converter lock-up is meant to limit transmission slip at certain speeds. If the lock-up system is faulty, the transmission could overheat after a prolonged use.

Faulty cooling system - In some vehicle designs, the engine cooling system also serves to cool the transmission also. The transmission is cooled by the cooling system via the heat exchanger.

Heavy load/Towing - When there is heavy loading on the automatic transmission either by the vehicle carrying heavy weights or by towing, the transmission temperature rises.

With these points known, I believe that you can now better take care of your automatic transmission like a baby and it will not fail you easily.
