I own a pre-facelift S8 with a gearbox now stuck in limp home mode,
and unless it's something small like F125 switch, it's looking fairly likely it's
time for a change - the car has 146k on it, 36k of which were mine, so
she's well in the danger zone.

I was wondering what is required to carry out the manual conversion?

My car has the 32v AHC engine, the only conversions I've read about are
in the states using 01E DSY Audi B5 S4/RS4 gearboxes, and on facelift
40v cars, so I know that it may not be indicative of what's to be done on
a pre-facelift.

As far as I know the manual in the Euro S8's was a 01E DGV gearbox,
are there any other cars that had this box, maybe TDIs?

I assume that a different driveshaft would be needed, would the stock
S8 manual driveshaft be available form Audi?

Pedal box, clutch cylinder, linkages would be necessary, would the same
half shafts be ok?

Does anyone have a parts list of what is necessary to carry out this conversion?
