Question

How practice I make clean out the fluid in the torque converter?

Yous would take to take the transmission apart to do that. When it doesn't work properly, then usually the torque converter is bad. (The gas mileage goes down and RPMs go up.) This can happen intermittently on the motorway every bit the torque converter is going bad.
Question

What should I do if my transmission sometimes gets stuck and revs high?

The first thing to do is change the manual oil. Most cars use a type of oil which has solvent mixed into the oil. As the solvent evaporates, the viscosity increases and the oil becomes likewise thick. On onetime cars, adding a transmission condiment would piece of work neat in many cases. On a CVT Transmission, doing that would void the warranty. You might take a bad manual.

Changing the filter will assistance in maintaining the cleanliness of the fluid. It is responsible for trapping modest metal filings or other contaminants from the fluid while it moves through the manual. On older cars, information technology is not recommended to alter the transmission fluid because the clutch plates etc., have deposits of contaminants and debris on them and have worn into running with them in place. If you lot modify the fluid, you may dislodge these deposits, and your transmission will operate worse than before! Changing fluid is not going to repair a broken or worn transmission parts.
