Unlikely. The vehicle will certainly not move as there will be no hydraulic pressure. Unlikely because there maye some newer cars with a pressure sensor that communicates with the BCM although I don't know of any off the top of my head.
Not changing the transmission fluid in a car within 200K would cause problems.
No
No, the engine is not dependent on the transmission or transmission fluid in order to start & run.
It will start to slip
Stripped transmission, low transmission fluid.
Are you asking the cause of the leak or cause of the not moving problem. If your fluid is low that may be the problem right there. YOU CAN BURN OUT A TRANSMISSION BY NOT KEEPING FLUID FULL!!!
Your motor oil going bad would cause that. That is in the crankcase, not the transmission.
Under the car, remove the bolt to transmission fluid container, and allow it to drain. Replace the bolt and add in a few quarts of transmission fluid, start the car and allow it to warm, check the fluid level and add more if needed.
Weak transmission fluid pressure. The fluid goes bad after many miles of use. Have the transmission fluid and filter replaced (about $100) immediately before the transmission goes bad. A transmission for that car cost more than the car is worth.
It is possible.
Maintaining transmission fluid in a car is important to keeping a car running smoothly. A person adds transmission fluid in the same tube of the dipstick, where they check the transmission fluid.
Yep. Too much fluid will cause foaming and will cause lack of lubrication. At what point this starts is anybody's guess.
