    I used Redline MTL. Works very well. Seems slightly smoother and is a little quieter than the stock fluid. Shift speed is about the same, perhaps a little faster on cool mornings. I didn't have any transmission issues on the stock fluid and don't have any now. Changed it out at 30K, stock fluid was medium/dark yellow, smelled ok, but I am glad I changed it.

    I would recommend this fluid and will use it again.

    For those in a cold environment, does changing the trans fluid seem to make shifting with a cold engine easier? I find it hard to believe Mitsu wouldn't put synthetic in from the factory, but if you guys are seeing improvements from it...

    It's slightly improved. My transmission is much better after 50k miles. Very precise and smooth.


    My magnetic drain plug has proof of its usefulness

    Just did this tonight at 60,258 miles. Thanks for the write-up, especially the part about measuring out the fluid. For those doing this in the future, it is easier than changing your oil.

    I used Redline MTL, as others here have, and noticed a bit smoother shifting.

    I'm at 36,000mi and ordered some Red Line MTL for a m/t fluid change. The shifter has seemed more notchy, but I attributed that to colder weather.
    I mainly wanted to flush the "wear particles" out and try out some good gear oil.

    Waiting for the MTL from Amazon, I took her in for the Airbag recall. The service man came to the waiting room and said, "We recommend a Trans Fluid Change." I knew the interval was 60k miles and said no thanks.

    I'm in the middle of said fluid change, and NOTHING has come out.
    I even jacked the rear-end up still nothing!

    I honestly don't suspect the dealer drained and didn't refill. I'm going to put some dye in with the redline and see if there are leaks....
    Pissed though wondering if it came from the factory dry. Can't prove it now though.

    P.S. $110 for dealer M/T change.

    Thinking of wear particles. I think I will fill it with cheaper oil. Run it briefly, then drain/refill with Redline. I don't want to have particles from a dry trans swishing around fro the next 30k. Any recourse you can think of. I can't prove it was dry at this point, and if it works??? (at least till 100K warranty)

    If it were dry, you'd have major issues. You can't run long without lube. The bearings will be destroyed.

    Sure you opened the drain hole as opposed to the fill hole?

    I was thinking the same thing.

    Dry? That can't be. I would expect significant damage if any transmission were run 36,000 miles without lubricant, much less 36 miles. There must be more to this story.
