sticky clutch

Hello all, I'm a bit stuck on this, any ideas please.
whilst driving my L reg 300tdi disco in traffic it became imposable to select or change gears or even take it out of gear whilst the motor was running.
I took the box out and fitted a new clutch fork, slippers and plastic clip that holds the release bearing to the fork. (nothing wrong with the old fork)
still the same problem clutch drag as I now know it's called.
I fitted a new master /slave cylinder and the damper. I treated myself to an easybleed kit to make sure all the air was out....... still the same problem.
I removed the gearbox again, and found the fingers on the pressure plate uneven so I fitted a new pressure plate / clutch disk and thrust bearing.
The clutch pedal feels perfect but still the drag.
so I ask myself did i put the clutch disk in back to front? I did double check and it was marked flywheel side.
There are no strange noises, the spigot bearing felt smooth and round, I cant see any end float in the crankshaft.
Any advise

Cheers
Jack

If you dont drive it in traffic does it make any difference ?

not much traffic here in norfolk

Are you sure the fork is as good as you think?Sounds like your just not getting enough oomph on the pressure plate ,to let the driven plate spin freely

I fitted a new fork "just incase" as the old one looked fine

Sorry I mis- read your first post,there's not lots of carpet and mats stopping the pedal going right down,or any other obstruction to the pedal

Did you clean/grease the gearbox splines ?
