- Make a note of what you were doing, where you are, what’s happening (noises, etc.)
- After cooling down, start back up & gingerly continue on your way.
What happens if your transmission fluid gets too hot?
Excessive transmission heat is responsible for the start of many transmission problems including; ruptured seals, cracked gears, slipping transmission bands, failed bearings, inoperable solenoids, and delayed clutch engagement. You name the part, and too much heat can cause it to break.
How hot is too hot for a transmission?
The optimal temperature range for transmission fluid is 175 to 220 degrees. Above that, for every 20 degrees bad things happen, starting with formation of varnish at 240 degrees, followed by seals hardening, plates slipping, seals and clutches burn out, carbon is formed, and, ultimately, failure.
Can you over cool a transmission?
Can you over cool the transmission fluid? Answer: Transmissions are not highly sensitive to cool operating temperatures. However, in sub-freezing (20-30°F) weather conditions, transmission fluid can actually gel up in an external cooler and cease to flow, causing damage.
What causes a transmission to run hot?
Old, worn out, or burned fluid will cause the transmission to run hot. Transmission slipping is another hint that the fluid is low and old. A defective solenoid can cause the transmission to run hot. Driving habits, conditions, and weather are other possible causes of transmission overheating.
How do you stop a transmission from slipping?

Can a bad thermostat cause transmission problems?
If the thermostat is stuck open
Temperature gauge reads lower than normal. Heater doesn’t work. Automatic transmission has trouble shifting into higher gears. Fuel economy drops noticeably.
What is a safe transmission temperature?
The ideal temperature for your transmission is 200 degrees. For every 20 degrees past 200, the lifespan of your transmission is reduced by a factor of 2. In other words, if you hit 220 degrees, you can expect to get about half the normal life out of your transmission.
Does transmission fluid expand when hot?
If the fluid level is OK when cold, it should also be within the cross hatched area for “H” as well. The reason for checking when both hot and cold is transmission fluid expands as it is heated. … Transmission fluid expands and keeps expanding the hotter it gets.
