When I finally got and installed an 87 kzf for my 87 442 you could not feel any of the shifts. It didn't slip at all just really no feel to the shifts. I removed the servo and found the smallest servo I've ever seen in a 2004r ,noticeably smaller than any mcss or even standard 200. I installed a CK performance billet servo and now it has nice crisp shifts that will bark second with heavy throttle. Every thing I've read about the kzf says shift points are about 4800 mine are a bit higher 1-2 is 5500 and 2-3 3-4 are about 5000. This is a sub 80k trans that's never been apart.
