I have a stick shift 2002 corolla with 71k miles on it. The problem that I am having is that after driving for a little while in stop and go traffic especially with ac on, when I press the clutch and engage a gear (first or second, third and fifth grind when this happens) I hear a pulsating sound from the hood (may be it is clutch chatter but I dont know what does clutch chatter sound like). Anyways if I put my foot on the accelerator at that time, the noise worsens meaning the frequency of the pulsating sound increases but than it disappears altogether as though something has been released. The car does not creep forward at all when this happens. I have recently had the clutch changed and all of this did not happen before changing the clutch. Anyways the dealer says that the spline with the pressure plate is either not lubricated enough or lubrication is way too much. The mechanic who changed the clutch says that since the forward gears grind and becoem stuck when this happens, it is the slave or the master cylinder. What do you guys think? Any help would be highly appreciated.
Thanks, Wajahat
