Hey guys, I get this weird grinding/biting noise whenever I shift to third gear. Other than that, the car runs just fine. I did just do a gear oil change in the tansmission. I used about 2.5 quarts of Slick 50 Gear Lube. Now I have this weird ass griding whenever I shift to third. It lasts about a 1/2 second. I found out that if I let the RPM's die and if I take time and go to third using two perfect 90 degree turns that there is no grinding. But that's unacceptable. Can anyone help?
