I have about 2400. involved with my swap.
level 3 4l60e w/ 2500 stall TC: 1550.
crossmember: 30.
wiring harness adapter: 214.
PCM reprogram from Thunder racing: 85.
dipstick:30.
A4 console 50.
A4 shifter cable: 45.
shifter ****: 20.
A4 shifter: 55.
hayden trans cooler: 50.
trans fluid: 50.
ARP bolt kit for flexplate and TC: 40.
SPI flexplate: 150.
poly trans mount: 25.
If all goes together well then thats what you should expect to pay. other than the new parts from thunder racing and the transmission itself, I purchased cosmetic stuff such as consoles,shifters etc off Ebay for way cheaper than new parts. It has taken weeks of planning and searching for deals on the internet. I've had absolutely no clue on how to do this but this site has been a huge resource for me. Asking lots of questions helps. Thanks to all that responded to my PM's. Will have the install stage completed by this coming Thursday and will post on my success. PM me if you need any help.

M6 to A4 additional note
I didn't include the torque converter in the above costs. I want to see how my car drives first then figuire out how much stall I want. Being as how this is a crucial component that effects my whole set up and the costs involved for a perfomance converter, I'll make sure to get it right the first time for my DD ride.

Can this swap be done without swapping an m6 harness for a a4 harness? I am swapping with a guy who has a m6 and he is relying on me to come up with the wiring that he will need to do. Please tell me someone has done this swap an kept the m6 harness. My car is a 98 and his is an 01. Those harnesses won't swap will they?

get a stall convertor. one that match's your heads cam. if stock, and performance is main goal, get like a 3600. 4000 stall if drag racing is your main objective. night and day diff. between a good 9.5" stall conv. to the stock one. but none of that will make the eng. make more power, or make the trans use less HP. and it will make the dyno think the eng. is making less power, but thats only due to the way the dyno loads against the engine. its misconcieving.
as for beefing internals on the stock 4L60E, yeah, thats tons that will make it stronger. not enough of a tranny guy to explain that stuff though. but like I said, none of that will make the trans use less HP.

They are expensive, but maybe I can sell all the M6 crap for a 4L80. I need to read more into the A4 conversion so I want to start collecting parts. I could kick myself for converting my car to M6 in the first place, it was fun for a while, but I want to start hitting the track more and an A4 is the only way to go.

Thanks for all this info guys, have a few questions.
What are these parts, and their part numbers?
Park Neutral switch and shiftlock controls
Shiftlock control wiring pigtail
And where are these located on the car?
Also How do I get my cruise controll to keep working?
