How do you completely drain transmission fluid?
If you need to remove the entire transmission fluid pan, unscrew the two upper-most bolts halfway, then unscrew the other bolts all the way. As soon as the last bolt is completely unscrewed, the pan may drop a bit and fluid will begin draining. You may also have to pull it loose using some force.
Is it better to flush or drain transmission fluid?
Proponents of transmission flushes will often argue that a flush is a better service because it replaces more of your transmission fluid. It’s true that removing your transmission pan or draining your transmission via its drain plug (as your car manufacturer intends) only removes about 70% of the fluid inside.
Do you drain transmission fluid hot or cold?

Why You Should Never flush your transmission fluid?

Will changing transmission fluid improve shifting?
If you catch a shifting issue very early, a transmission fluid flush can sometimes fix shifting issues. The fresh fluid helps clutch discs and steel discs bond and hold without slipping. The seal conditioners in the new fluid help soften the clutch piston lip seals so they seal better.
Is it bad to change transmission fluid on high mileage?
Changing the transmission fluid on a high-mileage car is risky. Don’t do it unless your transmission is running fine and the fluid is first-rate, because it can make transmission failure imminent.
How much does a transmission fluid flush cost?
