Frequent question: Can a transmission run too cool?

Heat is a huge cause of transmission failures but running too cool is bad also. Just as an engine has to run hot enough the trans has to run hot enough to get rid of any condensation that builds up inside and to keep the viscosity at the correct level for best operation.

Can you over cool a transmission?

Can you over cool the transmission fluid? Answer: Transmissions are not highly sensitive to cool operating temperatures. However, in sub-freezing (20-30°F) weather conditions, transmission fluid can actually gel up in an external cooler and cease to flow, causing damage.

Can transmission temp be too low?

The ideal temperature for it is 175 degrees, plus or minus 25 degrees, and when the transmission gets below zero degrees, it gets too thick. The fluid can also fail to lubricate parts when it is too cold, wearing parts down unnecessarily.

What can cool down a 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.

What is dangerous temp 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.

Can you have too many transmission coolers?

When it comes to your hot rod you really can’t have too much of a transmission cooler, but you can certainly not have enough. You will find there are various different types of cooler designs available and each has their own level of effectiveness.

What is Max transmission temp?

We allow for up to 285 degrees F in extreme conditions (i.e. towing a trailer with combination loaded at GCWR in Death Valley). But for customer usage anywhere else in the country, even at GCWR, transmission sump temperature should stay well below 270 degrees F.

How do u know if your transmission is slipping?

If your transmission is slipping, be aware of the signs.

  1. Engine revs or chugs.
  2. Slow, weak or delayed acceleration.
  3. Difficulty shifting gears or hard shifting.
  4. Grinding, whining or other strange noises.
  5. Won’t go in reverse.
  6. Burned or strange smells.
  7. Check engine light.

When my car is cold the transmission is slipping?

If your transmission slips only when it’s cold, then there could be three possible reasons. The first one could be that your engine is low on transmission fluid and could use some more. … The second reason could be that the fluid has become old and denatured, and needs to be changed.

  3. After cooling down, start back up & gingerly continue on your way.

How do I keep my transmission cool while towing?

Adding a simple auxiliary cooler inline with the factory unit can nearly double the life of transmission fluid, keeping your gearbox happy and healthy for a long time. Also helpful are aftermarket aluminum pans. Their added fluid capacity and finned heat-sink design provide additional cooling as well.
