Kiwibirdman Posted June 20, 2020 Share Posted June 20, 2020 Does anyone know if earthing the PWR/ECO mode on a VT commodore 4L60E puts it into PWR mode or ECO? In my drive round the block the trans felt like it was in PWR mode with the wire not earthed. Quote Link to comment Share on other sites More sharing options...
