Hey guys I'm new to this site and recently I blew my tranny out. I took it to a transmission shop and he said Im missing second gear. I dont know what to do, i really want to swap from my A4 to a M6 but money is issue for me being cause im in high school still. I need some info on what to do or any advise on getting cheap parts or how much this will cost me? or a parts list for a t56 swap and prices? Or if i should just stick with a A4? Please help.

The cost of the M6 swap depends on the cost of your swap parts. I would say $2000 is the minimum and it will probably be more. If you have a 2.73 rear end you will need to change it. There was a M6 used on some 93s that would work with the 2.73, but it would be hard to find and you may have problems with the speed sensor. Except for cutting a hole for the shifter and some wiring the swap is just replacing auto parts with manual parts. Your PCM will need to be flashed with a M6 tune.

I've done the swap and ,unless you really want a M6, I think you should have your auto rebuilt. It will be a lot less work and probably cost a lot less. You also won't be taking a chance on a lot of used parts.

Thanks for info and advice. I believe my rear end is 3.23, and ya that's one of my concerns about taking a risk with the used parts. If my rear end is 3.23 do i have to change it?

I think 3.23 would be okay. 94 and later M6 cars came with 3.42.

This link will give you an idea of what is involved in the swap.

Thanks for the help guys! I will look into it some more, and see if i can afford a M6 swap.

I don't know I've done a few of these swaps and the first time its a pain because your learning but its pretty easy. 2k seems steep. I think you can get it done less than that. Heck I scored a GTO T56 for my 73 Firebird for 450 on Craigslist. yes deal of the century but I've seen the setups minus hydraulics for less than a grand.

If you are mechanically inclined I say do it, the auto is a PITA you really have to find a good builder, if not its a roll of the dice and your spending another 1100-2000 in a year.

I wrote up a piece on LS1tech that goes over what I learned years ago. I'll try and find it.
