hi im a new member and i wondered  if anyone can help ive got a beauty of a 2.8  intercooler lwb every so often the speedo stops working when it does this the gearbox wont change into top gear has anyone got any ideas help please

That's normal when the speedo stops working as the overdrive takes it's que from roadspeed.

Most problems in this regard seem to involve the speedo head itself but check the wiring as it's all electronic
