Have just bought a Tranny MH and got a problem with the speedo. When doing 30 it shows 20, when doing 50 it shows 65!! And so on...! Obviously not that great for speed limits... and speed cameras!
Is there anything we can do? It had a newer gearbox fitted during the summer ~ could that be causing it?
It's a 1987 D reg 2.5 diesel.
Hope someone can help me
Many thnx
