Thanks Dave RAVE reckons MV3 is lock up valve. Where is the valve block for the auto gear box. I assuming its a specialist job to fix those valves? Thanks for the help

Thanks for the help guys. It doesnt lock up even at 60mph or 100kmh. Cant seem to get it to lock in 3 gear either? any ideas what would cause this. Stall test didnt indicate an issue with torque converter. Gear box shifts smoothly

Please help from NZ My 2001 td5 ES will not lock up in 4 gear at 50mph at all when the car is warmed up. I have managed to get lock up when cold but once warm and I have to slow down or speed up and it goes out of lock up it won't lock up again. Have had gear box flushed 3 times but no remedy...
