How many kilometers should transmission fluid be replaced?

[LaGabriel]

Transmission fluid should be replaced approximately every 80,000 kilometers. The functions of transmission fluid include cooling, lubrication, and power transmission. The method for changing transmission fluid is as follows: 1. Remove the transmission guard plate, loosen the screws on the oil pan, and drain the old transmission fluid; 2. Unscrew the screws on the oil pan and remove the oil pan; 3. Apply sealant to the new oil pan and tighten it; 4. Loosen the screw on the left side of the transmission to add new fluid. The consequences of not changing transmission fluid include: 1. The transmission fluid will become thicker, obstructing the transmission cooler; 2. The fluid will deteriorate and its viscosity will decrease, causing the fluid particles to enlarge or produce debris that blocks the oil passages; 3. Accelerated wear of mechanical components, damaging the automatic transmission planetary gear set and differential; 4. Corrosion of the gears inside the transmission.
