Hi, this harrier 3.0 actually is yr 2004 and reg on 2006 model is MCU31. When u drive, u put D, then when the gear change to 2 there will a bit problem. Then when change fr 2 to 3 become free gear. Mean that gear 3 4 5 is free can not use. After service the gear box n change the clutch pad it become normal and this problem solve. After 6 months later, this problem come again n we found that the clutch pad also gone, why become like that? Is it the C3 clutch got problem? We did check the wiring and meter on dashboard all function well. By the way I also add the speed meter on it, dont think that it will affect this problem.
