I have a 2013 Ford Mustang with an MT82 6-speed manual transmission. I don't know the history of the car so I figured it would be a good idea to change the transmission fluid. I drained it out and pumped new fluid back in.

I have done many automatic transmission drain and fills but this was my first time owning a manual car. I believe I may have underfilled it a bit. After reading online the car was not completely level and was at a slight incline probably causing the fill hole to falsely...

Did I hose my transmission?
