What causes dirty transmission fluid?
Just like the oil in a cars engine, automatic transmission fluid {ATF) suffers from heat, friction, oxidation and electrochemical degradation. Once this process starts, a transmission’s vital parts begin to clog with sludge and varnish deposits.

Will changing transmission fluid help 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.
How do you know if your transmission fluid needs to be changed?
Things such as trouble going into gear, hard shifts or thumps between gears, slipping or jumping gears, delay in acceleration, and strange noises such as whining or grinding are all signs it’s time to change the transmission fluid.

A change is done by dropping the trans pan and letting the old fluid drop into a catch pan. You would then have the opportunity to replace the filter and clean out gunk from the magnet in the pan. You replace the pan and add new fluid. One quirk about this is the trans fluid doesn’t all drain out.
What should I do if my transmission fluid is brown?
