I have a 2003 chevy cavalier, and just replaced the radiator due to a transmission fluid leak into the antifreeze. I don't know how much fluid was lost because the transmission was designed without a dipstick. The car seems to drive fine so far. I have also heard that adding too much fluid can damage an automatic transmission.
How can I tell if I need to add fluid, and how much fluid, to an automatic transmission with no dipstick?
