Discovery 1 300 tdi new clutch will not get no gears

Hi could any one help me with a problem I have with my 1998 landrover discovery 1
I fitted another transfer box last week and thought I'd change clutch at same time , after fitting new clutch / relise bearing & put a heavy dutey clutch fork in when I start my landrover and try to select any gears I can not get it in to gear at all if I turn it off and try to start it in gear with the clutch pedal down the clutch is still engaged
I have read through all the forums replaced new slave and master cylinder
Manually , reverse , and pressure bleed the system I have a good clutch peddle .
On another forum some one sead it could be new pressure plate faulty so I took it back out today and used my old pressure plate still no difference
Hopefully some one on here has a solution cheers

So the clutch is not releasing?

Friction plate fitted the correct way?

Hi lynall I fitted a valeo clutch it did not have fly wheel side of gear box side written on friction plate so fitted it the same way that my old one came out with flat side facing flywheel ?

Hi lynall yes it is not releasing I fitted a valeo clutch it did not have fly wheel side of gear box side written on friction plate so fitted it the same way that my old one came out with flat side facing flywheel ?

Hello and welcome to LZ

So the only other thing that’s different is the transfer box. Not that I can see how that would affect it though.

300 TDI with R380 I’m assuming

Hi and welcome

Here’s a crazy thought, clutch arm is fitted correctly??
