    Changing Trans and diff fluid

    OK. I think I have a diff fluid down.

    -Jack the car up
    -Make sure that fill bolt comes off
    -Remove drain bolt
    -let all of the nasty old fluid drain
    -Put drain bolt back on and fill from the fill hole
    -put fill bolt back on - DONE

    Is that right? Also what kind of fluid should I use. I'm afraid to ask anyone in autozone.

    How do I go abouts changing the fluid in the Tranny? I'ma use the tranny cock tail in the tranny.

    Also can our tranny cocktail be used on other cars. Let's say a 96 Eagle Talon Tsi ?

    THANKS

    I wouldn't mix rear diff fluid - just get fluid that is specced for your usage - 75w90 is plenty fine. I used Valvoline gear oil.
    I do have some Redline fluid sitting around but haven't used it.

    Fill the rear diff up to the point where it starts to run out of the fill hole.

    Also - when filling, make sure the car is level (front back), otherwise you will not be filling it to the right level.

    I used a siphon pump to fill the diff because it's hard to get a bottle in there with the right angle. Turkey basters work too, but it's a lot slower.

    It's easy enough to do, so I bought enough fluid and redid it about 2 weeks later.

    rear diff, drain from the bottom hole, fill from the top hole.

    You may want to jack up the front of the car to get some additional fluid out.

    I use subaru extra S for the tranny. Terrific stuff. If you can get some I would highly suggest it.

    well no one here that works there doesn't do nearly what you do. they are all high schoolers or high school drop outs with riced out civics. except for one, but he's an asshole that doesn't help anyone.

    Cool, seems simple.

    I have a Manual Tranny. I didn't think I had a dipstick

    I run this mix in both my Legacy and coincidentally, my AWD DSM.

    1 qt. Redline shockproof heavy, top it off with Redline MT 90 for the gearboxes. Medium shockproof goes in the diff in the Subaru, heavy in the Talon.

    I couldn't find the fill hole on my 97 brighton last time I looked. Does anybody have a pic?
