Most problems i have seen with these types of boxes are with the actuators not ecu

If the actuators are not doing what they are meant to do then the ecu just goes to sleep

There are so many things to check you need someone who understands the system to pinpoint the problem area.

just to let anyone know gear actuators knackered , cheaper to buy 2nd hand box complete with actuators so whilst removed replaced clutch as well etc...re fitted replacement box ,programmed up with planet ( 2 mins of a job ) all works well now car back on road drives like new...in total a good days work if anyone else thinking of doing.
