How often should the transmission fluid be changed for the Mistra?

[DelGavin]

The transmission fluid for the Mistra should be changed every two years or 40,000 kilometers. Since the Mistra does not have a dipstick, when draining the fluid, loosen the screw at the bottom of the transmission. For refilling, there is a plastic screw marked '22' on the top housing of the transmission—removing it reveals the filling port, and a funnel will be needed. Disassembling the intake pipe makes it easy to locate. More details about the Mistra's transmission are as follows: 1. The Mistra requires 4.7 liters of transmission fluid. Transmission fluid is an oil product that keeps the gear system clean, providing lubrication to extend the lifespan of the transmission components. It offers effective lubrication even at low temperatures and reduces oil loss under severe operating conditions. 2. Under normal driving conditions, the transmission fluid temperature typically stays below 135°C. However, excessive use of the vehicle, such as towing heavy loads or driving in four-wheel-drive mode set for snow or off-road conditions, may cause the transmission fluid temperature to reach 135°C due to excessive torque converter slippage.
