The box changes perfectly(way better than standard with the aftermarket valvebody). I have all gears etc. It's just the lockup TC that drops in and out at 90 to 100 km/h. And only when its really warmed up (after 20/30 mins of driving) so hopefully it has to do with the temp sensor.
Another strange thing is if I get straight onto the highway I can drive for over an hour at 90/110 km/h and it won't play up. But if I drive around country roads it starts to play up after 20 mins or so ?
