Default clutches and doubleclutching

Ok, first off, I had an argument today with my mechanic about doubling clutching. From what I have gathered, it not only saves your tranny (synchros) from mashing, it also saves your clutch because you put less wear on it by matching revs. What are you guys' and gals' opinions?

Second off, I tried changing the clutch on my teg this evening with my mechanic. It didn't quite go as planned because the tranny was bolted on so tightly that we couldn't get it out with an impact gun. I want to take it to a shop to get it done. Does anyone know of a shop in NoVa (northern virginia) that does good work for cheap?

Actually, I would think you'd be wearing it out faster because you have to push in the clutch, take it out of gear, push it back in, put it back in gear as apposed to pushing it in, and switching gears.

That's what the synchros are there for.

I'm not clutch expert but I do double clutch to save my dying 3rd gear synchros. I am thinking that double clutching prevents damage to your transmission but wears out your clutch more because you are actually making two clutch/flywheel connections instead of one, even though the second connection is pretty low impact since the revs are almost matched in theory.

I double clutch religously, and my synros are wearing out. But I have 115K miles; that could be just normal.

Even if it does wear the synros, I'll always do it b/c downshifting is so much smoother for the passengers when you double clutch.

BTW, how much does it cost to get the synros replaced by the dealership? It sounds like something I shouldn't try myself.

I don't know how much they charge for labor but I think just the parts is upward of $300. Add in the labor for taking out the tranny and taking it apart, replacing the gear set, putting it back together, reinstalling the tranny, and you are probably better off buying a new used transmission with low miles.

its just as smooth as rev matching on a downshift, double clutching is a waste of time.

ive never found double clutching to be a waste of time. Depending on how you drive, it could save the clutch more than not double clutching. For the life of me I dont know how you could downshift, without double clutching. (you could hold the clutch in and hit the gas but it takes just as long imo)

thats exactly how you do it...

clutch, pull it into gear, blip the throttle, let out the clutch....how is that not faster than double clutching?
