    Okay..
    I have never been able to mash into 2nd gear at a high RPM.
    I have 11K miles on the truck, and it is supercharged.
    I have not gone to the track, because I can not hit 2nd gear without babying it in.... Kinda sucks.

    Well, low and behold, I have heard rumors about people changing the fluid to Redline MT-90, and problems going away.
    I said What the hell.
    I bought 3 quarts of Redline MT-90 from Summit (Local stores near me dont carry it).
    My cost was $32.00 with shipping.
    Under the truck, there is a drain plug right at the bottom of the tranny. You cant miss it.
    It is a 15/16 head on that bad boy:

    Crack it open, and get your oil pan ready to catch it.
    Careful, it is easy to make a mess, it does not drain very smoothly... it kinda goes glub glub glub till its empty.

    Then look about this on the drivers side of the tranny, you will find the fill plug :
    [​IMG]

    remove this plug and get ready to fill....
    Now...
    Filling is the tricky part of this job...
    Tom and I did it this way...
    We fitted the quart with a rubber hose.
    then duct taped a smaller host into that one the smaller hose fits right into the hole in the tranny).
    heres a pic:
    [​IMG]

    after we made that one, we took out the small hose and redid it.
    Same way, just put a much longer small hose in it.
    Tom stood in front of my truck under the hood, and ran the small hose down to me.
    I stuck it in the hole (hehe)
    and he started pouring.

    This tranny holds 1.9 quarts.
    We went ahead and dumped 2 whole quarts in.
    When I removed the hose, the extra dribbled out, and I put the plug back in.


    End Result:

    I can get in 2nd gear at redline without a grind at all. The difference was 100% noticeable 2 minutes after I got on the road.

    Edit -
    I am not sure if its in my mind or not, but my reverse seems a little softer going in now too.

    Added suggestions:
    1. You can also fill it where the shifter mounts
    2. Take the fill plug out before draining (helps with draining)

    Pulling the fill plug first helps a little, not much

    Just want to vouch for the Redline MT-90, this stuff is really good. I changed out the manual trans oil a couple days ago with only 5k on the odo and even though i had no problems with my transmission, i noticed an immediate difference. Gears feel smooth and like "butter", i would highly recommend changing out your stock oil to this one and also doing the recommended 30k change down the line as well back to this oil again

    I used plain Redline 75w90, Feels Excellent. I noticed an immediate diffrence, in every gear. Nothing major but its enough to make the 1/2 hour spent doing it worth it.

    I got mine changed a couple of days ago. There was a night and day difference with the redline. Others may not of had the same outcome but mine is 10 x better at shifting now and like Rob said, seems easier to get in reverse. I would also like to think Rob for the write-up, very easy to do but knowing what your getting into before hand always makes it that much easier :top:

    The fill plug.. i got one of those funnels that has about a foot long tube on it from walmart and then added about 2 more feet to it and had my helper pour in two bottles of fluid (i was holding the tube in the tranny) until it started coming out of the fill plug hole :top:

    Well I Went To The Local Truck Performance Shop To Order My Redline Mt-90 And The Owner Said Rather Than Changing The Mt-oil I Needed To Use An Additive. So I Bought A Pint Of A Local Mde Additive Called Mt-10!?. Holy Sh!t It Worked Miracles. Its Like This Bottle Converted My Truck To An Automatic. Shifts So Smooth And Easy.
