1987

Hello i am looking for a user manual or handbook (i've seen some form Haynes) for a 1987 Chevrolet Cavalier RS 2.8 V6 Manual 5 speed Convertible. The main issue i am having is that i cant find the correct motor and gear oil for my car aswell as how much.:confused:

My tranny is going out on my 1987 350 5.7L Suburban it is a 4 speed auto tranny.. It only drives in 2 gear no drive, but if you put it in over drive and go over 35 mph it will shift hard into over drive but then it just wants to go lol.. anyone have any suggestions on how to fix it or know...
