I use B&M 'Trick Shift' fluid which is a synthetic ATF, blue in color, and I mix in 2 oz. of Sta-Lube FM that CSK sells and mine shifts really good when cold or hot. It's also quieted down the tranny a lot too. Tranny doesn't growl when it sits there and idles anymore
Also put that same B&M stuff in my power steering too and it seems a lot smoother when cold too
I just tried it on accident because that's all the local CSK store had for synthetic ATF when I went there, but now that I seen how good it works for me, that's all I'll ever stick in it now. Plus it's a cool shade of blue
