Hey guys hoping someone on here could help me diaganose a problem. I have a 1994 honda civic ex 2 door coupe 1.6 sohc. I am having a problem when shifting into third gear. When I get in the car in the morning and the car is dead cold I can drive/shift normally. After maby I min or 2 of driving the car grinds when I shift into third gear. All other gear changes work properly. If I rev it up pretty high in second , push in the clutch, and let my rpm's go to to idle I can shift without the grinding noise. Oh yea my car has 147,000 miles and I put in a new clutch assy/ and bearings at 131000. Any advice, besides shift from 2nd to 4th?
