I have metric 200 tyranny on my 86 Cutlass with the 307 and as of late been having problems with it shifting into drive it doesn't want to go pass reverse feels like something is in its way and times it goes into gear,now another problem persists when I go into reverse is hesitant but after a while it goes and there is a slight grumbling noise and feeling under floor then it goes in reverse... Now could my transmission be going out or cable maybe too long when trying to go into drive that it doesn't catch and just did transmission fluid and filter change because before had no reverse and doesn't go all the way in park now when changing transmission fluid it's supposed to be in park right...going crazy over this please help me out.
