What to Do When the BMW X1 Transmission Overheats?

If the oil level is too low, open the rear part of the transmission, locate the oil filler port, and use an oil filler to add transmission oil until it starts to overflow, then tighten the screw. Under normal driving conditions, replace the transmission oil and filter every 2 years or 60,000 kilometers to filter out impurities in the lubricating oil and clean the transmission oil pan. After parking and turning off the engine, wait a few minutes before attempting to open the radiator cap to check and replenish the coolant, or wait until the engine coolant temperature cools down before driving. Visit a 4S shop for inspection; if necessary, replace the entire torque converter assembly or the internal friction plates of the torque converter.
When I was driving the old X1, I encountered a transmission overheating warning. At that time, the dashboard displayed a yellow gear symbol with a thermometer icon. In such a situation, never push through it. Immediately pull over, shift to P, turn off the engine, and let the transmission cool down for half an hour. It might be due to the radiator being clogged with willow catkins or the transmission fluid not being changed for too long, leading to poor flow. Last time I checked, it was because the active grille was stuck, causing insufficient airflow. If this issue occurs frequently, it's advisable to inspect the coolant circulation pump and the transmission fluid heat exchanger, especially during summer highway driving, which can easily trigger the overheating protection program.
