If you have an automatic transmission and it "slips" while you are driving it—that is, the car engine revs without the power going to the wheels—the most common cause (though not the only possible cause) is low transmission fluid. If the slipping is caused by low fluid, it will get worse as the transmission gets hotter.

Will overheating a transmission slip?
Causes of Overheating Transmission
This can quickly overheat the transmission, as the additional weight causes the transmission to have to work harder than normal. This can cause the bands and clutches to slip, especially when the drive wheels aren't on the ground.
Can too much fluid cause transmission slip?
Excess transmission fluid can cause several adverse effects to the transmission. If the fluid stays above the recommended level, it can cause it to start mixing with air. This can lead to gear slippage, hard shifting, and other transmission shifting issues.

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.
