How hot is too hot for transmission?
#1 Cause of Failure 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.
Is 180 degrees too hot for a transmission?
(180°F to 200°F). So, this manual indicates that the normal automatic transmission oil temperature range is 180F – 200F. If you have a temperature gauge on your transmission oil and find that it exceeds those numbers you should be adding an extra transmission oil cooler to your vehicle.
What is normal operating temp for Allison Transmission?
180-200 approx
Normal operating temps will range from 180-200 approx. 100 degrees above ambient air temps. These transmissions will run from 200-230 in the summer months when towing in hilly areas. These temps are normal and will not hurt the transmission.
What is the normal operating temperature of a Duramax?
How Hot Should My Duramax Run? These engines are designed to run at a normal temperature, so anything below 235 is normal. Whether you tow or not, anything under 220 is fine for your trans. A solid 235 to 240 if the factory DEX VI is present is a reasonable guess.
Is 230 degrees too hot for a transmission?
Fluid Life Expectancy vs Temperature 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.
Is 165 a good transmission temp?
Mine’s between 165-170 when fully warmed up and cruising on the highway. A little city driving will take it up to 175.
Is 170 hot for transmission?
Ideally, the fluid temperature in the automatic transmission would range from 170 to 225 degrees Fahrenheit. If the transmission is slipping or you are pushing the vehicle hard, the temperature could rise above 240 degrees. However, with every 20-degree drop, your transmission remains better protected.
Does the radiator cool the transmission?
All transmissions have a cooling line that runs to the radiator. A separate fluid passage circulates the transmission fluid through a portion of the radiator to cool the fluid.
