4R70W Question???
Guys,
Why would my transmission shift so smooth into 2nd by manually moving the shift lever to 2nd verses leaving it in "D" & Letting it upshift on its own. I Am trying to solve this horrid 1-2 shift problem. Also Just cahnged the accumulator spring & piston with new design. Wondering if it may be a solonoid due it shifting flawless when I manually shift it???
