Hello Scotty I have a 2010 Toyota Camry 4 cylinder automatic transmission 95,000 miles. When I bought this car used I figured I'd change the transmission fluid since I don't know if it had been changed already I drained it and replaced it with OEM Toyota ws atf fluid. When I drained it the fluid was very very dark and looked like it had never been changed. I replaced the same amount I drained but my question is when should I do it again considering that the fluid was very dark and dirty the first time I drained it and is there a filter I should change? How should I check the ATF fluid level I've seen videos telling me I need to check the temperature of the fluid? Thank you for your time!
