For the Baojun 510, if you are manually changing the transmission fluid (gravity method), you will need to add four to six liters; if you are using a fluid exchange machine, you will need to add approximately nine to twelve liters. Different vehicle models have different replacement intervals. Below are the recommended replacement intervals for transmission fluid: Manual Transmission: Manual transmission fluid is generally recommended to be replaced every three years or around 100,000 kilometers. Automatic Transmission: Automatic transmission fluid is generally recommended to be replaced every two years or around 40,000 kilometers. Continuously Variable Transmission (CVT): CVT fluid is generally recommended to be replaced every two years or around 60,000 kilometers. The methods for changing transmission fluid are as follows: Loosen the drain plug at the bottom of the transmission to drain the old fluid, then refill with new fluid. Remove the transmission oil pan directly to drain the old fluid and refill with new fluid: This method is more thorough than the previous one, as it allows for the removal of debris at the bottom of the oil pan. Use a circulation machine to change automatic transmission fluid: A smart circulation machine can perform dynamic fluid exchange, filtering and cleaning sludge and debris inside the automatic transmission.

Last time I helped my friend change the transmission oil for his Baojun 510. For the manual transmission version, it required about 1.8 to 2 liters. For the AMT automatic version, it needs slightly more, around 2.5 liters. When changing the oil, pay attention to using the manufacturer-recommended 75W-90 grade oil. Adding too much can cause oil seal leakage, while adding too little won't provide sufficient lubrication. It's best to add the oil when the car is cold. After adding, start the engine and shift gears a few times, then check the dipstick level. Generally, it should be changed every 20,000 kilometers. After the change, I clearly felt smoother gear shifts. Older cars especially need regular maintenance.

I've been driving the 510 for three years, and my experience with changing transmission fluid is that a 2-liter bottle is sufficient for manual transmissions, with about 1.9 liters actually being filled. For automatic transmission models, it's recommended to prepare 3 liters, with approximately 2.5 liters being used. The method of changing the oil is crucial. This amount applies to regular gravity oil changes. If you use a circulation machine, it will waste over ten liters, which is really unnecessary. A key reminder: the oil level must be between the minimum and maximum marks on the dipstick. It might not be accurate right after filling; you need to drive a bit and then check again. If you're doing it yourself, buy a filling tube and add the oil slowly—don't rush. Overfilling can cause the transmission to feel sluggish.

This is a common question from Baojun 510 owners during maintenance. The manual transmission requires 2.0 liters of oil, while the AMT automatic transmission needs 2.3 to 2.6 liters. The key factor is the refilling method: gravity draining generally follows this quantity, but the thoroughness of oil drainage affects it - remaining old oil means less new oil needs to be added. Currently, factory-approved oil is recommended, with 75W-90 viscosity being most suitable. Reminder: pay attention to oil temperature - the oil level rises when the engine is hot, so filling to the middle mark when cold is safest. After changing, remember to test each gear - crisp shifting sounds indicate no problems.

In our car enthusiast group, we've discussed that the Baojun 510 manual transmission requires about 2 liters of gear oil, while the automatic version needs around 2.5 liters. The actual amount might be slightly less due to residual oil affected by the drain port position. It's recommended to inspect the filter screen and oil pan during oil changes—metal shavings indicate significant wear. Don't use the wrong oil type; the original 75W-90 offers the best gear protection. Those who frequently drive on highways might consider changing the oil at 30,000 kilometers. If shifting feels rough after adding oil, it's likely due to insufficient oil quantity.
