The automatic transmission fluid performs two vital roles – lubricating and cleaning. The liquid circulates through various parts to reduce friction between them and gather sediments that can circulate through the system and cause damage. You need to change oil for automatic gearbox at regular intervals to keep the car running and healthy.
Things You Should Know While Changing the Automatic Transmission Fluid (ATF)
If you want to carry out the procedure of automatic transmission fluid flush into your garage, it’s necessary to have knowledge about some things.
The color is red
The color of fresh transmission liquid is bright red and smells sweet or like a tart. You need to change it if the texture turns into a smoky dark shade and it reeks a burned odor. Use a dipstick to see if the fluid is fresh or becomes blackened. Besides, the dipstick is also handy to measure the level of the liquid. You will need to fill up if the level is low.
Flushing is necessary for burnt oil
The fuel changes its color because of the heat and for collecting dirt and metal shavings over time. If you don’t flush the chamber at the time of filling it up with new fluid, there’s a chance that the sediments of the old burnt oil will flow throw the system. It’s risky because the dirt can damage various components. So, you need to flush out the old fuel at the time of changing.
Clean the torque converter too
Everyone knows about cleaning the transmission pan and replacing the filter but amateur people forget about the torque converter. In fact, half of the burnt up automatic transmission fluid and the contaminants remain in that component. You should also clean up the valve body and clutch drums if want to get the full benefit of change oil for transmission gearbox.
Seal the pan properly
If you find dimples around the bolts of the pan rail, flatten them with a hammer and dolly. Not doing it will leave you with the risk of a leaking pan gasket sometimes later.

Don’t use a silicone sealant because it will break off eventually and increase your problems by clogging the pump intake.
