At what temperature does transmission fluid breakdown?
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. At 240 degrees, seals start to harden.
What temp is bad 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.
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 to transmission fluid in cold weather?
Change fluids: Besides transmission fluid, other fluids in your vehicle—oil, antifreeze, etc.—thicken in cold temperatures, which means they don’t move easily and in that state are not thin enough. When thick, they can tear seals or cause other problems.
What should the transmission temperature be to last the longest?
What is the optimum temperature for the longest life of the transmission? 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.
