Well the question is have any of you used REDLINE MTF in your manula terannys and has it messed anything up i recently got 4 qts for free and im wondering on putting it in

 

nope always used 10W30

 

I believe I heard it's a thinner fluid so the shifting should be easier, compared to a fluid thats a little thicker (more restriction). But a lot of people prefer going oem with trans fluid. Honda's brand you get at the dealership. But I have heard good things.
