Disadvantages of the Getrag 6DCT470 gearbox
- The main problems with this transmission are related to rapid wear of the clutch pack;
- The solenoids become clogged with wear debris, causing jerking or pulsating;
- The plunger plugs in the valve body often burst and fall out, causing pressure to drop;
- Another weak point of this robotic transmission is the short-lived damper springs;
- And don’t forget to update the internal fine filter; not everyone knows about it.
