Question '04 WRX Installed: New Transmission and Clutch but Still Grinds and Does not Move

I am about to drop my transmission for a third time and I am dreading having to do it if I really don't have to. After the first go-round, I ended up replacing the transmission entirely, and purchasing a new clutch. Once I put everything back, started it and tried to shift into gear, it made a horrible grinding noise. So we dropped it again only to discover that my friend put the clutch in backwards. Ugh. So we switched everything around, replaced the clutch release bearing because it was bent all crazy, and put it back in the car. Now, I just came in from starting it and shifting into gear and the grinding noise came back and the car won't move. Any suggestions as to where to look now? I don't want to drop the tranny again if I don't have to. Thanks!

Have you bled the clutch master and slave at all? If you KNOW everything is bolted in right then that would be my next suspicion. If itís grinding that means itís trying to do something at least. Could be you arenít getting enough hydraulic power from your master and slave cylinders to engage/disengage the clutch

Lets be honest, if your friend put the clutch in backwards the first time then there is no telling what else he did wrong lol

Its possible you damaged the pilot bearing during installation, its also possible that the pressure plate is not properly aligned, hell for all we know it could be in backwards too!

Are you positive you installed the correct components for that make? Is everything OEM? Are any hoses leaking? Does the clutch disengage?

Did you fill the transmission with gear fluid?
What gear fluid did you use?
