Why is my transmission running hot?

An overheating transmission usually means there is already some sort of internal damage or a transmission fluid issue, such as a leak, low fluid level or just old/dirty fluid running through the system. It can also happen with too much transmission fluid, which causes excess pressure within the transmission.

Why does my transmission shift hard when hot?

Transmissions shifts hard when hot because their parts tend to get damaged, worn, and malfunction under high heat levels. Your transmission needs fluid to keep cool and if the fluid leaks then it may create more heat and pressure.

Can low coolant cause transmission overheating?
