Where is the manual transmission oil filler port on the Corolla?
2 Answers
The manual transmission oil filler port on the Corolla is a screw located on the transmission housing, which can be seen after lifting the vehicle. Manual transmission oil is generally recommended to be replaced every three years or approximately 100,000 kilometers. The method for replacing Corolla transmission oil is as follows: Unscrew the drain plug at the bottom of the transmission to drain the oil before refilling. Remove the transmission oil pan directly to drain and refill the oil: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to replace automatic transmission oil: Dynamic oil replacement with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission. Different vehicle models have different replacement cycles. Below are the replacement cycles for transmission oil: Manual transmission: Manual transmission oil is generally recommended to be replaced every three years or approximately 100,000 kilometers. Automatic transmission: Automatic transmission oil is generally recommended to be replaced every two years or approximately 40,000 kilometers. Continuously variable transmission (CVT): CVT oil is generally recommended to be replaced every two years or approximately 60,000 kilometers.
I've been driving a manual Corolla for almost ten years, and finding the transmission fluid filler port requires crawling under the car. It's located on the upper-middle left side of the transmission, right next to the driveshaft, usually as a hex socket screw hole. I recommend jacking up the front wheels for safety. Once you locate it, don't rush to unscrew it—clean the surrounding dust first to avoid contaminants falling in. Use a specialized funnel to add the fluid slowly, stopping when new fluid starts overflowing. Remember, the fluid change interval is around 60,000 kilometers, and while you're at it, check if the transmission mount bushings are cracked, otherwise, shifting gears might cause vibrations.
