I have a 1995 gmc sierra with a 305 and a 5 speed maual trans. My problem is at start up is goes into gear just fine, but once the engine is warmed up and i start getting traffic lights. Since i have it in nuetral and try to put it in gear it wont go in. In other words can't put it in gear without strugling and grinds when i try to put it in reverese. Has any one had this problem or know what i'm talking about.
