transmission issues! please help!
So I just put a new clutch in my 2006 GTO. Car drove real good for about a month. After driving the car pretty hard for about twenty minutes I parked and it sat for about two hours. When I came back to it it wouldn't go into reverse. I tried everything. Putting out into drive gears, staying in reverse, everything! Finally after about five minutes I got it into reverse, with a lot of force. Car drove home fine. Parked it for the night. The next morning it was acting up real bad and it's been like it ever since. It is really tough going into 1-4 at low rpms. It goes into every gear fine driving it hard. But fifth great has been the weirdest. It goes in really easily but I can feel it grind every time it goes in. I'm really not sure what the issue is. Nor wanting to spend thousands chasing this problem around. Also, when the car is in gear and moving at any speed, if I rest my foot on the clutch pedal I can feel it pulsing. It made a really weird noise that first morning when it starting acting up but hasn't really done it since. Someone please help! I'm driving cross country soon and I don't want to have a break down half way.
