cant figure it out my 3 and 4 gear is grinding a little at high RPm any solution? Maybe because I need a new clutch.

 

it's your synchros.. very common! It is covered under the 6/60k powertrain warranty

 

After looking @ his sig, I highly doubt his warranty is still valid.

Like the person above me said it's probably your synchros.
Try adjusting the clutch pedal (just a bit higher).
If that does not help, get ready to replace your sychro.
Good luck.

 

If you have a act clutch then there is your problem they tend to lock out on high rpm.

If not then it time to send your trans out to shep or tre.

 

I have heard grinding 1 time, when I mis-shifted passing someone in 3rd shifting to 4th, bad sound - it hurt me too. What car is this, a IX or 8?

 

try changing your tranny fluid, if problem still persists, i'd look into a new synchro.

 

i think is the clutch.

 

I have the ACT and have no problems...................now that i have a Shep Tranny!!!

 

I had the same problem 3 to 4. It ended up being the synchros.

 

I had the same problem from 2nd to 3rd. I replaced all the shifter bushings with metal ones and changed the gear oil. Problem solved

 

my does that too from 4th-5th on high rpm...

 

If you need repair and choose TRE...think twice before sending out...had bad experience.
