Vanquish uses a slushbox by Graziano doesn't it? It's a good transmission and I would leave it alone.

 

No, the Vanquish (gen 1) uses a Tremec manual (single clutch) that is electrohydraulically operated. The factory manual conversion uses that original gearbox, replacing the electrohydraulic stuff with a gear lever and a clutch pedal. The gen 2 Vanquish (2013-2018) uses a ZF torque-converter automatic.

 

Some guys in the UK have done a manual conversion and really thought about it. They have created a new pedal box that shifts the pedals away from the side giving you somewhere to rest your left foot. They have also put the gearlever in the right place. They are a fraction of the Works costs and can do the conversions in the USA.

 

That would be Aston Workshop.

 

There is one on Bring A Trailer listed today!

 

Q Branch Automotive have done it. Correctly as in manage the software, fit proper detents in the box so you know which gear you are in etc. Not using a blanked out gear display window to hide "Gearbox Fault"
