Why is my transmission slipping?

Transmission gears wear out and start slipping.

Over time gears can wear out – especially if they have been running hot and inefficiently due to lack of or worn out transmission fluid. Slipping gears are usually due to normal wear and tear, which causes them to not engage properly and to slip in and out of sync.

Why does my transmission stop working when it warms up?

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.

What makes a transmission overheat?

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.
