Hi i have a 78 daimler soveriegn with a 4 speed overdrive box. The clutch is slipping when overdrive is selected, The overdrive unit has been doing this since i have owned the car ( 4 years ) so i have not been using it. Recently It has begun slipping when selecting reverse gear. Does anybody have experiance with these gearboxes or know of anyone in the south island of NewZealand who can help. Thanks

Nic
