What causes high transmission temp?

What causes high transmission temp?

Why is my transmission temperature light on?

Transmission failures are one of a vehicle owner’s worst nightmares, as they are notoriously expensive to repair, and one of the things mostly to damage your transmission is overheating.

What transmission temperature is too high?

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.

How do I lower my transmission temperature?

Transmission fluid additives contain special coolants designed to reduce the temperature of your transmission, particularly when it is under strain from stop and go traffic, driving on hilly terrain or carrying extra weight. Transmission fluid additives can be purchased at most auto supply stores.

How do I check my transmission temperature?

Install the scan tool, start the vehicle and look for the transmission temperature. The fluid temperature should be between the 185- and 194-degree marks with an idle of 600 to 800 rpms.

How do I cool down my automatic transmission?

External Coolers Installing an external cooler can prove greatly effective in cooling your transmission and keeping it at a regulated temperature, which helps to prevent damage. External coolers also help to reduce friction to the transmission, which is another common cause of damage.

At 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.

How do I cool down my transmission?

When was the worst year for Subaru transmission problems?

The 2012 Impreza was probably the worst year for transmission issues with drivers complaining of problems shifting properly and random acceleration. Even though this was the worst year for the Impreza, that doesn’t necessarily mean it was a chronic issue by any means and not a regular problem for most Impreza drivers.
