I did it 2 weeks ago. Not too tough. Getting the M6 pedals out is a pain and so is making a cover for the huge hole that will be in the tunnel from the M6 shifter. If you have any questions, ask away or PM me.

Mounting the shifter was the biggest pain. Other than that it's just bolts.

What about the console? I am getting ready to swap out my M6 for a TH400. Can I use my old console? Or do I get a console for an automatic?

First thing is to make sure you have everything. That being said, here are some tips:

1. Drop the steering colum to take the pedals out. It'll make things much much easier. Also remember where all of the plugs go. Take a pic if it'll help.

2. You're going to have a decent sized hole in the tunnel where the M6 shifter came up thru. You'll need to cover this. Here is what I did. Get a piece of decently think sheet metal atleast 18"x18" and some self tapping screws. Trace the hole onto a piece of paper. Then cut the metal 1" larger than the trace. You'll only be able to go 1/2" bigger on the top (front) due to space. From there line it up. Then drill some holes thru the sheet metal and the tunnel. Keep the holes you drill as close to the lip of the tunnel hole as possible (1/4-1/2"). Use a very thin drill bit. I made 2 on the top, 2 on the bottom and 3 on each side. That was more than enough. Then screw it down. After you've got it screwed down you'll need a rubber mallet. You'll notice you have all of the edges sticking out. Beat them into place with the mallet. After a bit they will all fold down nicely and it'll lood good. Then go under the car. Fill in the new "seam" of the cover and the tunnel lip with some black RTV sealant. Use plenty and go around the entire rim. Allow that to dry. Then mock up your shifter to see there your shifter cable will come thru. It should be on the drivers front part of the cover. Then go back under the car and drill thru with a 2" hole saw. Feed the shifter cable up and pop the rubber gromet into place.

3. A lift makes things very easy.

Here's all that you will need parts wise.....

4L60E with bell housing
A4 shifter
A4 wiring harness
A4 crossmember
A4 flexplate
A4 upper console
A4 pedals
Trans dip stick tube
Converter
Trans cooler
And you'll need an A4 tune thrown in it or have it reflashed to an A4.

If you have any other questions, feel free to ask.

For the TH400 you can probably get away with the same upper console piece. The lower piece is the same on both. But it'll depend on the shifter you use.

Thanks man that was great. Sorry took me so long but I had some serious training and was away from the computer. I'm just wondering if its worth the effort. As far as the wiring harness goes.... do I have to get a complete harness???

Yeah, you'll need a complete A4 harness.

If your going to a th400 then I dont think youll need a harness since its not needed....your just have to figure out the wiring for back up lights and neutral start switch and not having a speedo but I'm sure theres companies that makes adaptors for it.
