Here's the thing with our cars: Because they are high horsepower/torque, the synchros must be able to withstand the torque/hp associated with higher rpms. As a consequence, at lower rpms, the synchro's simply don't work as well.
There are 2 solutions to this problem:
1. Shift very quickly. If you don't let the engine rpms drop too much then you'll get smoother shifting. The longer you wait between shifts the better job you need to do modulating the rpms through gas pedal.
2. Shift at higher rpms. You'll still need to shift quicker, but the synchros will work better because of the higher hp/torque.
With all that said, you may have damaged your synchros but I'd be surprised if you did any damage to your clutch or pressure plate...
I gotta ask, on point 1... at low speeds I find going into second its better to shift a little slower because when I shift really fast, the engine revs are higher than the wheel speed so it grips, bites, and shakes the car (very unsmooth shift) and thats when I hear the grinding. If I clutch in, shift, pause
, clutch out - the revs fall and the engine speed matches the wheel speed, minimizing syncro wear (which is what I thought was going on) and the grinding is much more quiet. Are you telling me that by doing what makes it quieter and smoother is actually damaging my car? If so - boy howdy I am gonna start shifing much faster!
Also, my local indy said I was damaging my pressure plate. How would I have damaged the syncros? These transmissions are pretty beefy from what I understand, and the whole point of syncros is to alleviate wear is it not? Forgive me if this is a stupid question, I am just thirsty for knowledge
I really dont want to mess up my syncros and have to get a new transmission for 4K since there is no rebuild for these...
I got mine at 60k and am now at 97k, 2 years later.
This isn't the original clutch, though. People before me beat the hell out of the clutch and (if my mind serves right), this is the 5th clutch that my car's seen. I'm the 3rd owner, too. I know that the clutch was changed a lot at first because I checked the service records.
5th clutch! My goodness, thats one every 20K miles or so! Hopefully yours will last longer, it certainly sounds like you know how to properly take care of it even if the previous owners did not...
