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.
How hot should a automatic transmission run?
Normal operating temperature for an automatic transmission is about the same as the engine temperature, i.e., about 195°F. The temperature inside the torque converter, while pulling a big load from a standing start, could easily rise above 350°F.
How hot is too hot for ATF?
If fluid temperatures can be held to 175 degrees F., ATF will last almost indefinitely — say up to 100,000 miles. But if the fluid temperature goes much higher, the life of the fluid begins to plummet.
How do I lower my transmission temperature?
Tips and Tricks to Cool a Transmission
- Use an Additive. One of the simplest things you can do to keep your transmission cool and extend its life is to use a transmission fluid additive on a regular basis. …
- Go Neutral. …
- External Coolers.
What makes a transmission overheat?
An overheating transmission usually means there is already some sort of internal damage or a transmission fluid issue, such as a leak, low fluid level or just old/dirty fluid running through the system. It can also happen with too much transmission fluid, which causes excess pressure within the transmission.
Is 230 degrees to hot for a transmission?
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 180 degrees too hot for a transmission?
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.
How do you warm up an automatic transmission?
Start the engine, allow it to stabilize and idle for perhaps 15 seconds, shift into gear, wait a few seconds for the transmission to fully engage then drive the vehicle up to temperature gently.
What is a good coolant temp?
Normal Temperature engine temperature gauge
Most experts agree that your engine should run between 195 degrees and 220 degrees. In ideal situations, your needle will maintain a posture right in the middle of your gauge.
What is normal transmission temperature in Celsius?
A question that gets asked the alot is what is the best temperature my automatic transmission should operate at? Most late model vehicles operate at 90°C – 95°C which is quite normal and what the transmission control module will operate its smoothest shift strategy.
What are the symptoms of an overheated transmission?
3 Symptoms of Transmission Overheating
- Acrid Burning Odor. Transmissions change gears using principles of hydraulic power. …
- Slow Response Times. A transmission stands a much greater chance of overheating if fluid levels drop too low. …
- Transmission Slipping.
How do you know if your transmission is getting hot?
Is My Transmission Overheating?
- A sudden experience of a burning odor inside and outside the vehicle.
- The gears “slipping” when accelerating or decelerating.
- A feeling of hesitation or delayed gear shift when you are driving.
- Any grinding or shaking sensation that occurs while accelerating or while idling.
