    I was doing a drain and fill on the trans, was not thinking right and instead of filling thru the 24mm plug facing the radiator, I filled thru this 10mm hex head in the driver's side wheel well. How bad is this? Does this plug go to the trans or somewhere else? Not starting or driving the car until I figure out how bad I messed up. Any help would be greatly appreciated.

    I don't know how much of you put in and what's happened now go check it properly? What do you have? If it shows full and everything looks good leave it alone.

    I've seen numerous fill places but if you open the 24mm and ensure it's, indeed, full, you should be good to go! (I had a Scion with a little 1.3L engine and the transmission, also, had a few different access points...probably used during vehicle assembly at the plant.)
