My 07 plate ST2 focus won't go into gear at all when running and 1st -3rd when not running no 4th, 5th, 6th or reverse clutch is 600 to fix that ,already had to replace the oil filter housing unit, the oil pressure switch twice as the first one was faulty and replaced the dipstick and tube with new oil seal 600 on those if any one has any ideas why this is happening or has had similar problems please message me back as any suggestions would be very useful not to mention appreciated.

 

Sounds more like a selector problem Trevor, i know the St has a interlock to stop you going into reverse when moving and stops you selecting 5&6 when stationary. This interlock gets a signal from the abs sensors so maybe get a code reader and see if there are any abs faults present before you rip the gearbox out.
