So let me start with giving a little history on the car:

I replaced the engine approximately 4 months ago. When i replaced the engine, i decided to change the clutch and the pressure plate (used) since the engine was already out and it made it easy.

After driving the car for a couple of days, i took my car to get aligned. When i received it, my gears were grinding. So i approach the manager since i thought they had screwed it up while taking it out for a spin. So, i get the car the next day and according to them... they said that the clutch fluid was low, and they bleed the system... I really didnt believe them but my problem went away

So whatever, 4 months later... my car started grinding all the gears again. It wont grind the gears as if i missed a gear, it'll grind when its all the way in and i release the clutch.

If i shift any time after 3000 rpms, itll grind.
IF i shift under 3000 rpms, it wont grind.
It will grind in all gears if over 3,000 RPM.

What do you guys think it could be?
Air in the system?
Syncros?
Clutch and pressure plate?



I replaced the clutch and pressure plate with a used one but did not replace the flywheel.
I changed the transmission oil.
I checked the fluid, and the fluid is full.

Please help!!!!!

Mines doing the same thing except its only in first and reverse and low rpms when shifting. I believe its a bad throwout or pilot bearing. Im taking the clutch out next week to actually get in there and look around.

Do you know if your pilot bearing and throwout where changed? Or did they just reuse all the old ones off your car?
