What temperature is too hot for transmission fluid?

If the temperature gets above 250 degrees F., rubber seals begin to harden, which leads to leaks and pressure losses. At higher temperatures the transmission begins to slip, which only aggravates overheating even more. Eventually the clutches burn out and the transmission calls it quits.

What happens if your transmission gets too hot?

A transmission that frequently overheats can cause fluid to leak from the transmission, so if you are constantly replacing the fluid, it’s a good indication of a leak.

How high is too high for transmission temp?

The ideal operating temperature of transmission fluid is 175 degrees. Overheating occurs after the temperature surpasses 200 degrees, and the failure rate doubles for every additional 20 degree increase after that.

At what temp does a transmission overheat?

Without enough transmission fluid or effective fluid, your transmission will start acting out. The ideal fluid temperature is under 175 degrees, but as fluid ages it starts to break down and lose its capacity to cool down the transmission. This is when transmission overheating occurs. At 220 degrees, varnish forms.
