Automatic transmission fluid or ATF is formulated for complex mechanism of a vehicle’s transmission system. Automatic transmission fluid also contains anti-corrosives and other substances that have the tendency to keep the transmission and its parts free from rust for loner period of time. It is strongly recommended not to use the motor oil in the transmission system. It can be dangerous as it is not refined and harmful for transmission system.
You’ll Need

Following material is required to replace the automatic transmission fluid:

• Automatic transmission fluid
• Catch or drain pan
• Clean rags
• New transmission filter and gasket kit
• Safety goggles
• Socket wrench and screwdriver set

Instructions

Following are given the instructions which will guide you to change the transmission fluid:

• Park the vehicle and set it on ‘Park’ mode. Locate the ATF dipstick at the back of the engine bay. It is usually labeled as “ATF.”
• Inspect the dipstick carefully and see the marking of the fluid on it. Remove the dipstick and clean it with a cloth, again put it in the reservoir and pull it back again. See the fluid level on the dipstick it should be at ‘Full’ or just below it.
• Examine the quality of the fluid also. Check the fluid, if it is clear or not and also the odor of the fluid. If it is not clear and smell like burned oil, you need to replace the fluid.
• Place the drain pan under the transmission fluid pan.
• Unfasten the bolts or screws holding the TF pan to the chassis. Make sure that you will not spatter the fluid while draining it out. It should be drained in the drain or catch pan.
• Take the old gasket away and clean it with the rag properly. Later, using the appropriate wrench, remove the transmission filter.
• Wash the transmission pan properly and make it free from any dirt and debris.
• Follow the manual’s instructions and install the new transmission filter and gasket kit accordingly.
• Fix the transmission pan afterwards.
• In the end add new fluid up to the required mark, i.e. up to “Full” mark.

Keep checking the fluid level regularly for better performance.
