some time its very hard to shift the car when your doing a 1/4 miles runs. and sometimes when ur doingshifting you will hear it grind going in....also when doing a good run the shifter vibrates and makes a grinding sound

 

Mine does that too. I think it has to do with the clutch hydraulic hose having a restriction from the factory. Do a search for the drill mod, I'm planning on doing that soon.

 

Mine grinds when I'm trying to accelerate quickly and I shift hard from first to second. If I'm just cruising around though and shift it smooth it doesn't grind. I figured it might be a synchro.

 

same problem here..

 

i just had my spec 3 and flywheel put in, i am having the same prob my car shifts fine when just driving around but as soon as i hit over 6000k its extremely hard to shift and sometimes grinds and wont go into the gear!

 

If you're getting it in multiple gears it's more than likely a clutch or alignment problem. Synchros going usually only show up in 1 or 2 gears.

 

deff in the tranny and not a clutch problem.....it was fine last saterday only started having the problem till i bolted on the slicks and made a few pass on the street.....probly dosent help the car is making 480flbs to the gorund
