grrr.... over reving problem is back :S ! ...
ive tested the vacuum valve with wires direct from battery..... its mechanicaly functional,
however following green books ive done some checks and the current to the vacuum valve never moves from the low ratio side to the overdrive side
im thinking that this is a microswitch fault stopping it changing up
at the moment im having to put up with revs around 40000 when traveling at 30mph... not good
ive had belts checked (good)
clutch clearance (good)
4 way vacuum valve seems ok will probably change it to be 100%
microswitch,,,, pretty sure its not working right will change it as soon as i source a replacement..
any ideas what to try next if changing the valve and microswitch makes no difference ??????
