I read that you shouldn't mix certain kinds of trans fluid in these cars. I wanna do a flush and fill but don't wanna mix with the wrong fluid. Has anyone dealt with this problem before? When getting my filter kit it was a warning from Lexus to not mix trans ll or something along those lines. I just bought the car and i'm not sure what's in it right now. Any help on this would be great.

 

Go to Toyota and ask for Type IV tranny fluid. TII is now Type IV.
