Thanks again.

 

I wonder about failures with the S2 and Turbo... I bet alot less are R&P but more other stuff...

 

Tifo,, i need your help again. Heres teh part number off the tranny i just got from the guy, assuming its the right one.

AOT18119

Is this the part im looking for?

 

Looks like it was made on November 11, 1989.

But the first three numbers don't make sense. Here, look at this graphic below:

 

So the only A prefixes should be ASG or ASH right?

 

Shiza. Sorry for hijacking yoru thread tifo.. i just did a vin check on the car he took it out of. It is a 1988 944 S... So is this tranny okay for me? It will still be stronger than pre 88 NA trannys supposedly right?

 

That is the code for a 944S2 tranny with optional LSD. The 18119 code says the manufacturing date is 18 Nov 1989, so probably out of a 1990 944S2. The S2 trannies had similar gearing to the NA trannies, but much stronger R&P gears. Assuming that it is in good shape, you should grab that tranny real fast. If a fellow Rennlister asks who is selling it, you should lie.

I think that the tranny is a direct bolt-in for your car, but you should check with someone more knowledgable.

 

Tifo any word? Coudl this be true? I searched the VIN WP0AA2946JN465518 for the car it came out of, which is definately a 1988 944 S i think anyway!

Wow... I think ill pay a big *** deposit now then. Are you sure thats what the AOT means

 

Page 30-02b of the 944 Factory Service Manual, Vol. 2, Version XXIV, 1991 says for transmission type 083F, code AOT indicates "5 speed with lock, 944 S2, worldwide except Switzerland, model years 1989/1990/1991." As Tifo indicated, the manufacture date is November 1989, so there is no way that could be the original transmission from a 1988 944 S. It must have been changed at some point in the car's history. The 944 S used type 083D transmission with code AGP (worldwide without LSD) or code AGR (worldwide with LSD.) Since the 944 S tranny still used the weaker R&P gear of the 944NA, maybe the PO had to replace the tranny because of a broken R&P gear.

 

!!!!!!!!!!!!!!!!! Thats amazing. Wish me luck! Tifo if your out there can you confirm this? S2 Tranny will bolt up right?

 

The AOT code is for an S2 trans with Limited slip and it will bolt up.

 

Dude -- that's the Holy Grail of NA trannies! I've been looking for one for a year and a half now. If it really is an S2 tranny with LSD, you'd better pick it up.

 

Devon, you're a lucky guy.
It will be MUCH more difficult to spin now!
Congrats and good luck.

 

Oh my. I'm going psycho.. I sure hope i'm not getting my hopes up for no reason. LSD Could have been taken out of it, right? Will the gear ratio differences be a big problem if i'm nto tracking it, just daily driver? Is it really that noticeable?

When I get this. How can I tell if it is LSD? Can i just turn the cv flange by hand and see if they both spin the same way? Does it have to be in gear to do this? Can you tell by hand what is too much and too little slack? thanks.

Im really sorry Tifo for killing yoru thread. If you want we can all delete our posts. Just obviously I've hit a chord here.

 

Sorry Tifo, the reason it isn't scrap metal is that I hope to rebuild it one day and put it back in, I really miss having LSD at autox events.
The S trans is a nice swap in an NA the gearing is similar to the stock NA trans but FWIH the R&P is as stout as the 951 R&P. The S2 trans has gearing that is similar to the NA but the ratio of the R&P is a bit taller, an S2 trans in an NA would be similar to having a 951 trans in an NA.
