What is Max transmission temp?

Although newer synthetic fluids can withstand higher temperatures we still recommend this (270F) as a maximum temperature.

Can a transmission run too cool?

Heat is a huge cause of transmission failures but running too cool is bad also. Just as an engine has to run hot enough the trans has to run hot enough to get rid of any condensation that builds up inside and to keep the viscosity at the correct level for best operation.

What temp does ATF breakdown?

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.
