Well, if it helps you - the TII and NA input and output shafts are different, so the bearings would probably be different too. Since the NA tranny's main problem is the input shaft bearing failing, and I haven't heard it so much the TII, that further argues against it being universal.

 

I guess you could look in the Parts Fiche and see if the numbers match up.

 

NA Main Gear Bearing - M502-17-295C
T2 Main Gear Bearing - R421-17-295
NA Main Shaft Bearing - M503-17-204
T2 Main Shaft Bearing - R421-17-204

Looks like the first 4 identifies the transmission, the rest IDs the type of part. Lucky you I just happened to have the parts fiche open already.

 

this is the reply i got

Hi,
Yes it is misleading and on my list to fix, the one on the website is N/A only the turbo is $100 dollars more, sorry for the confusion.
Thanks Ernst

What is needed to put a s4 T2 tranny in an NA s4 other then the custom driveshaft?

 

a jack, 4 jackstands, 10mm socket and ratchet, 12mm socket/wrench, 14mm socket/wrench, 17mm socket/wrench, a catch pan, 3 quarts of syncro safe 75w/90 gear oil (read manual to figure out how much you should actually use), the $8 neat little screw on handpump to put it in the transmission WAY easier than trying to feed it in from the top with a long hose, 3 hands, 3 beers, and 4 letter words.

Things that help? Air ratchet, removing exhaust before dropping transmission, haynes guide, ratchet extensions, a lift, and a friend who's done it before.

Things to remember, in order -

drain transmission before removing driveshaft

remove driveshaft before dropping transmission (this is where you find out why you need 4 jackstands, because your wheels don't turn with the e-brake on, and the driveshaft doesn't turn with the rear wheels on the ground)

disconnect reverse switch and 5th switch before dropping transmission

remove shifter before dropping transmission

transmissions are heavy

if you're directly under the transmission when you lower it, and you lower it onto your chest, not only will you not have enough room to set it down, you also won't have enough leverage to push it back up enough to get out from under it, even if you're very strong, especially if you tried to remove the transmission without removing the exhaust first. This is where having a friend helps, because after they're done laughing, they'll usually help you get out from under the car. Also, make sure your friend didn't choose that moment to go get another beer or buy cookies from a girlscout, because while having a transmission on you probably won't stop you from breathing, it will stop you from being able to get enough air into your lungs to yell. Don't ask me how I know.

Oh, and if all else fails, there's a bolt under the starter, and you should disconnect the battery before messing with it.

 

Dud thats hilarious.

It's much easier to use a jack under the transmission though, or you can have someone hold up the rear, take off the hood, and put a rope or chain around the tranny and send it up to use to lower it, a little tricky to do, but i installed a tranny by myself doing this.

 

Oh yeah - usually I use a jack on a towel over a piece of wood to get the tranny up and down more easily - the day in question, my friend who has never worked on Rx7's, but has a Camaro decided that we didn't need to take the exhaust off, so instead we tried to fight the transmission off from around the exhaust pipe for 30 minutes, twisting and pulling and not getting crap - but if you LOOKED at it, there didn't seem to be any reason why it wouldn't come down - then this girl scout walks up to ring his door bell, so he climbs out to help her - shortly thereafter I thought to myself, Hmm, if I twist it this way, and give a tug here - *thump* transmission in the chest. I could breathe, but I couldn't say anything louder than the radio - all I could do was wave my leg.

That taught me an important lesson about late model cars - if it looks like it's going to be in the way, go ahead and remove it - it may SEEM like more work, but it's much easier in the long run. By not taking the 5 minutes to unbolt the two bolts on the exhaust and drop it and pull it away, we wasted about 45 minutes trying to get the damn thing out - then we ended up pulling the exhaust to get it back in anyway. You live, you learn.
