When to change the transmission fluid?

Transmission fluid plays a crucial role in lubricating the components of your transmission and prevents wear and tear of the parts. As it circulates through the parts, it can pick up dirt and metal debris over time. So, having your transmission fluid checked by a professional mechanic is good for your transmission system. To know when to check your transmission fluid, you need to check your owner's manual, but generally speaking, it doesn't need to be checked or serviced under normal usage conditions. However, under severe usage conditions, it needs to be replaced about every 90,000km(60,000 miles). Visit an authorized dealer/service partner for a more accurate transmission fluid check. Nevertheless, if you are doing the transmission fluid check on your own, you can take the simple steps as follows. First, locate the transmission dipstick while the engine is running. Take the dipstick out of the tool and wipe it with a clean towel to see its fluid state. If the fluid has gotten darker or looks dirty, it's probably time to change the fluid. Also, at the bottom of the dipstick, there are the minimum and maximum markings, so you can check the fluid level as well.

The process of changing your transmission fluid is similar to changing your engine oil. Let's learn how to change the automatic transmission fluid step by step.

1) Jack your vehicle up to locate the transmission fluid drain plug beneath your car.

2) Put a catch pan under it and carefully loosen the drain plug to allow the fluid to drain.

3) With the fluid drained, put the drain plug back in its place with a wrench.

4) To refill your transmission fluid, check your owner's manual and it will specify which product you should use.

5) To know the correct amount of the fluid you should put in, use a translucent bottle with the measurements on its side to know how much fluid you need.

6) Refill your transmission fluid through the dipstick hole. Use the funnel and add the transmission fluid.

7) Once the transmission is filled, put the dipstick back in.

8) Start your vehicle and let the engine run for about a few minutes to reach the optimal operating temperature.

9) When the transmission fluid is warm, check the fluid level with a dipstick. Depending on the dipstick, the markings can vary, but if it reveals you have enough transmission fluid, then you are good to go.
