Yep and it cost a whole lot, and lots of work to do it. Central Coaster has the long list of parts you need. I can tell ya you'll need the transmission, all the clutch parts, new driveshaft, and a Dana 44 if you dont want to tear yours up quickly.

I changed a automatic to a four speed in a 68 camaro.

I had to get a new pedal setup with brake and clutch.

Bell housing, fly wheel, pressure plate, disk and bearing.

I think you are in luck with the drive shaft.


I am not sure if the computer needs to be changed.

Speedo gear?


Transmission mounting

Console and trim parts.

Wiring of safety switches for interlock

I know it would be a big project. If you are going to us an aftermarket manual trans, be expected to pay close to $4300 at a transmission shop.

The conversion costs will most likely run more than the current value of the 84. You don't have a lot of options for a tranny. A Kiesler or Richmond Gear tranny will run $3500 for a new one. A used ZF6 will be less, but you will need to do some interior mods Cutting of the tunnel nder the console, much less install the clutch setup (pedals, hydraulics, etc). Don't know for sure but the C-beam may be different between the A4 and manual cars.

The ECM will peobably need a new chip and you will destroy the D36 rear end if you beat on it hard.

Probably be cheaper to sell the car and look for a manual tranny car.
