Hello, first off my 700r4 in my 84 z28 doesn't have park as in you put the shifter next to the P and it keeps rolling with a little clicking sound like its slipping past the thing to make it stop. Second you have to rev it up to about 4000 rpm's to get it to shift into 2nd and 3rd/4th(OD) are non-existent. Any help would be great, thanks!!!
