    Found the problem the hand peice had a blocked exhaust port . Thanks everyone for your help. Also do you need to use the clutch when using the air shift

    A mate of mine has just fitted a 12 speed gearbox to his R model and the air shift is slow shifting into reverse as well as between low and high . He has put new kits into the air gear on top of the gearbox as well as a new gear knob .The air pressure to the gear knob is 70 psi. Would anyone have any thoughts on what could be th problem
