Deep pockets. You can but its cheaper to just buy a new car. I saw a thread on here at one point where someone did. I think it was close to $4k-$5k. I think RPM can do the conversion. I know they can put autos in Vipers and Vettes. I'm sure they can go the other way.

To replace your auto tranny is just the cost of the tranny and the installation. To replace the auto with a standard requires buying ALL the standard transmission parts (transmission, clutch, flywheel, slave and master cylinder, pedals, linkage, wiring, etc, etc, etc.) and the cost of a major installation by a knowledgable installer. A BIG difference in cost and time.

I may have missed a few smaller things but here's a pretty complete list of what's needed to install an automatic into a stick car:
- Flywheel
- Torque tube
- Shifter assembly
- differential (unless your installing an A6 in a Z06, otherwise they're not interchangeable)
- Transmission
- BCM reprogramming
- PCM swap and reprogramming
- Fuse block replacement and/or rewiring (on 06 and later as both have slots for TCM fuses)
- Trans cooler lines
- Engine harness rewiring
- TCM harness (on 06 and later) or an aftermarket trans controller for a 2005
- Torque converter
- Trans fluid
- Exhaust system (possibly, as some systems won't fit with an automatic)
So it's a WHOLE lot more than just the transmission and installation.

I can tell you going from a A6 to an A4 is not only expensive but time consuming. If I had to do this all again, I would have sold my vette and bought another one with the version i wanted.. seriously.. so trade cars or sell yours and\then buy one with a M6 in it..

It sounds like you have to buy everything anyway so some money out is expected. I changed my A4 to a manual.
Off the top of my head you'll need (I'll add stuff as I think of it):
- the complete driveline for the manual, including the torque tube, clutch, slave and master cylinders
- clutch pedal and brake pedal
- both switches that go at the top and bottom of clutch pedal (one is for starting, one is for turning off the cruise when you touch the clutch)
- shifter (should come with driveline)
- manual transmission harness (If your car is an F-55 then the manual harness will mate up directly, if not you have to change the connector from your auto harness to the manual harness)
- to rewire the ecm for the manual tranny since you are eliminating the tranmission control module
- to have the ecm and bcm re-programmed with a Tech II to manual parameters
