83944

Hi all,

I seek the collective wisdom of this group. Sometime ago I acquired a 944 Turbo transaxle with an external oil cooler.

I am finding it difficult to see if it contains a LSD!

Cast into the case are a whole range of part numbers such at 016 301 231F/016 301 103/016 301 211F etc. but these do not seem to help

Any clues??

Andrew,

Just turn one axle stub by hand. If the other side turns the same direction, its an LSD. Opposite directions = non-LSD.

Hi Chris,

Many thanks for that...as always there is a simple answer.

I was expecting typical German exactitude with option codes etc cast into the tranaxle case.

Regs,

No problem Andrew - and welcome to Rennlist.

I've found that even though I have owned one of these cars for many years - and do almost all the work on it myself, I still check the forums for tips and procedural information. No matter what the problem, someone on this list has been there and done that, and has taken the time to share it with the rest of us. A quick search can save you a lot of money - and many headaches.

Good luck!

Hi Chris,

Thanks for your help. I have learned so much about these babies from this list. I started with an '83 944 NA, sold that & graduated to a silver '90 944 S2 late last year. She is such a delight to drive. I checked the transaxle last night - the axles rotates in opposite directions so I have a non-LSD version. I might sell it as I believe the gearing is more suited to the Turbo. I am though lusting after a 911SC but all I talk to here say that I should stick to the S2 given the balance and wonderful hadling etc. I just what to experience the 911 thing!

Cheers to all
Andrew

Normally the transaxle has a stamped number on the top of the "bell" section. AOR stamped code would be the LSD.

Yep, Lego is correct. Andrew, you can check there for the case code, stamped in - not raised casting numbers. Its the type and date of mfg.

The first characters in the stamping are the type:

AOR is the Turbo S trans (LSD w/ Cooler)
5R is the regular Turbo trans with LSD and Cooler
5P is the reg. Turbo trans w/ cooler, no LSD

The rotational test (same = LSD, opposite = open diff) is also telltale.
