Hi guys,im really confused here,722.683 box on 3 litre viano,oil temps going over moon causing blue smoke from box harness up to engine bay fuse box to gearbox ecu,often smoke goes tough wheel arches etc.
oil is still bright red-ish and levels correct.
is my torque convertor out?

If temp is true, blocked oil line? Do you have thermostat valve on tcu oil cooler? You reader does not rread actual gear so I doubt all info it is giving... have you checked is there oil in TCU or harness.

Edit: 722.6 box (depending on car and engine) rarely goes locked state. I have sometimes posted a chart where slipping area is shown, it is pretty large operating range.
