What to Do If Transmission Fluid and Coolant Are Mixed Together?

Transmission fluid and coolant mixed together solution is to replace the radiator and transmission fluid, need to pay attention to see if there is water in the transmission, if there is water need to deal with it quickly. Detailed introduction of coolant: Introduction of coolant: The full name of coolant should be called antifreeze coolant, meaning it has antifreeze function, coolant can prevent the cooling liquid from freezing and cracking the radiator and freezing the engine cylinder block or cover when parking in cold winter; Chemical composition of coolant: More than 95% of domestic and foreign use ethylene glycol-based water-based coolant, compared with tap water, the most significant feature of ethylene glycol is antifreeze, while water cannot antifreeze. Secondly, ethylene glycol has a high boiling point, small volatility, moderate viscosity and small change with temperature, good thermal stability, so ethylene glycol-based coolant is an ideal coolant.
Mixing transmission fluid and coolant is a serious issue, and I learned this the hard way through personal experience. These two fluids have different chemical properties - coolant contains acidic and antifreeze components, while transmission fluid is a lubricant. When mixed, they can form harmful gels that cause internal corrosion in the transmission and clog the cooling system. If you discover they've mixed, stop driving immediately. Continuing to operate the vehicle will accelerate transmission damage, potentially leading to repair costs exceeding ten thousand yuan. Quickly take your car to a professional repair shop. They'll drain all contaminated fluids and use specialized equipment to flush both the transmission and cooling systems thoroughly, ensuring no residue remains. It's also crucial to check whether radiator seals have aged or leaked, as this is a common cause of mixing. After repairs and refilling with fresh transmission fluid and coolant, you should test drive for several days to confirm everything works properly. For regular maintenance, frequently inspect fluid colors and levels - prevention is always better and more economical than costly repairs later.
