I bought this used car a few months back and it was running great. I had the oil changed 2000 miles ago and had them replace the manual transmission grease. A couple weeks ago it started lunging when in 2 and 3 gear. I thought it was just rough road but it keeps happening. It doesn't happen when you are accelerating or applying the break. Just seems to happen when idle running down the road. I have placed my hand on the gear shift and it seems to vibrate when this is happening. Not sure if I can duplicate for the repair shop staff. Do you think it is a clutch or transmission issue?
