Thanks for the help guys,
I will definately search the site some more to gather info before going into another shop. I do realize that my tranny starts in 2nd, and yes it is the 2-3 upshift in which the flare occurs. from there it hits 3 to 4 without any flaring or delay. When I drop into 1st, it also upshifts into 2nd just fine. I guess it's sort of broken down to either a bad modulator or a blown seal inside. I'd like to hope for #1...
