I'm curious about the condition of my 5th gear. On occasion, when I shift into 5th, it will chatter and not accelerate for a second or two. Now, it happens the most when I shift into 5th and then hit the gas. After my foot hits the pedal is when it chatters. Since I only hit the gas in 5th on the highway, that's where I get the problem. No grinding, just like it's trying to catch. The clutch is new, and the rear main seal is new and better NOT be leaking. None of the other gears seem to do this. Car has 130k on it. I've seen others on this board that have problems with 5th gear and I'm wondering if they might be able to help. Thanks!
