My 1997 Pathfinder SE has a manual transmission that seems to be on the fritz. The sound only happens for the first two or so minutes of driving and more so when it is cold. When I apply power in reverse it starts to grind/squeal, and it used to be the end of it when I shifted to 1st, but now more and more often it is making the noise in first too. The noise seems to go away if I rev the engine a little. The car seems to shift just fine between all gears after it has been running a little bit. The dealer in the area thinks it might be the throw out bearing, but says they would have to hear it to make a difinitive diagnosis. Does anyone know what my problem is likely to be? If it's important I have 104K miles. Thanks for any thoughts.
