What does Subaru AT-OIL-TEMP mean?

[Shane]

Subaru AT-OIL-TEMP indicates that the automatic transmission fluid temperature is too high. Below is relevant information about automatic transmissions: 1. Definition: The core function of an automatic transmission is to achieve automatic gear shifting. Automatic gear shifting means that while driving, the driver operates the accelerator pedal as needed, and the automatic transmission can automatically shift into different gears based on engine load and the vehicle's operating conditions. 2. Classification: There are four common types of automatic transmissions: hydraulic automatic transmission, mechanical continuously variable transmission, electronically controlled mechanical automatic transmission, and dual-clutch automatic transmission. 3. Maintenance Method: Start the engine and warm up the transmission fluid to about 50°C. Then move the gear selector through each gear position, pausing for 2 seconds in each, before placing it in the parking gear. At this point, the normal fluid level on the dipstick should be between the maximum and minimum marks. If it is insufficient, promptly add the same quality of fluid.
