Frequent question: Does coolant ruin a transmission?

It may seem like a rather remote possibility, but engine coolant, or anti-freeze can get into automatic transmission fluid. The temperature of transmission fluid is regulated inside the engine cooling system. … Any rupture of the internal radiator tank can allow coolant to mix with, and contaminate transmission fluid.

Does engine coolant affect transmission?

When the engine cooling system is working properly, the engine coolant passes over the transmission cooler in the radiator. … So the cooler won’t release the heat necessary for the transmission to cool off. The heat continues to increase in the transmission, causing parts to expand and pressures to build.

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.
