What causes transmission temperature to go up or down?
Automatic Transmission Temperature. As it turns out, transmission temperature can make or break a transmission. Almost all transmissions fail from a breakdown of the transmission fluid. This is caused by overheating the transmission fluid.
What is the normal transmission temperature for a car?
Keeping the transmission temperature between 175 and 200 degrees will allow the fluid to last the longest. This is the normal operating temperature for a transmission. Remember the fluid is the life line or blood of the transmission. Damage to the transmission fluid begins at 225 degrees.
What happens when an automatic transmission is overheated?
Most cars do not have an external temperature gauge for the automatic transmissions fluid. Instead, they are using a warning light or the check engine light to show up when the transmission is overheated. An overheated transmission can also cause the engine to go into limp mode to lower the risk of overheating.
What should I do if my Mercedes Benz won’t start?
Start the car and you should be able to get around 60 psi. When the engine is running and when you turn off the engine the pressure should stay steady. Always perform this test on a cold engine. Next, make sure that the fuel injector connections are secure and not loose. Check the fuel pump and the fuel pump relay.
What happens when the transmission temp is too high?
When the temperatures rise above the normal transmission temp, the transmission fluid will lose its viscosity, and this causes it to oxidize. The fluid varnish starts destroying the internal components of the engine like the valves.
Why does my automatic transmission not cool down?
If it starts rising, you can stop your car by the roadside and let the engine cool for a while. Later check your coolant levels and make additions when necessary. You can also possibly have air in the coolant lines or blocked lines to the transmission, which is causing it not to cool efficiency.

Why is my Jeep transmission over temp coming on?
I had the same issue with the trans over temp and fan coming on, had a transmission shop check the temperature and it was spiking up and down all over the place; however, when they checked the trans dip stick it was ice cold. They told me it was possibly a faulty sensor within a solenoid pack inside the trans.
