    That is what I use. I was being told by this guy to use a heavy friction fluid or use the B&M trick shift. I only put maybe 1200-1500 miles on my truck a year and do a B.G. 100% fluid flush at least every year. I know it is over kill but this is what I do. /forums/images/icons/tongue.gif

    i was told to use an additive called Lube Guard, which is a synthetic and (is suppose to) increase viscosity.

    I would do this if your tranny was built up and/or is higher performance because standard dexron III is grat but not at high temps. It gets pretty thin when really hot.

    just my opinion
