5spd help

[VICSVX]

so i finally put a 99 impreza tranny in and put a new clutch/pressure plate/throwout bearing/pilot bearing, but for some reason the car does not seem to want to move very fast in 1st and 2nd.

In 1st and 2nd, there is a lot of chatter from the tranny area (im guessing the viscous) and it barely moves...like the clutch is slipping. 3rd gear same thing but the car moves pretty decent and 4th/5th seem to work fine.

Can you give me ideas on what to check and how to check them? ive tried adjusting the clutch and the only thing that changes is the pedal stiffness. at a lost.

the car is driveable, just 1/2 gears are a little shady and the noise is crazy...like metal grinding on metal...but once in awhile (usually higher rpms) the noise will go away and everything works right for a little

help?

thanks
