Took mine in for the mot 3 weeks ago. Asked garage, very good Indy, to change gearbox oil and do the clutch valve.
Straight through for mot, gearbox definitely better still 2nd gear notchy but improved and he told me clutch valve not there.
Hadn't checked beforehand so I'll wait until it's on a ramp before I check it myself. Have to say it drives normally, any overrevving on upchanges when I 1st got the car I reckon was down to me
