What is the oldest transmission that will fit into 1984 944 with limited slip diff?

I have two 944 transmissions that I have swapped in and out of my 944.
One has tighter gears and one is looser.
The tighter gets off the line quicker but is not quite as comfortable cruising on the highway.
the looser tran is around 2300 RPMs in 5th gear and the tighter is about 3000 RMPs at around 60MPH.
I am pretty sure that these stock transmissions (manual both) did not come with a limited slip differencial.
I want to have a limited slip diff. Can I put one into these transmissions?
If not, what 944 manual transmission that comes already with a limited slip diff will fit into my 1984 944?
Like from a 944 turbo or 944 turbo S?

If anyone has or knows of someone who has a transmission with a limited slip diff, please point me in the right direction.

thanks,
Robin Hood

You can use any year 944 or 968 transaxle.

ZOO,
@zoo

So you can put the 1986 and onwards 944 limited slip diff into my existing 944 transaxle?

I see this one on Design911 that says for 1986 onwards
https://www.design911.co.uk/p/limite...n-porsche-944/
Do you mean that I can use this one?
Or are you saying I can put a 968 5 speed manual transmission in my 1984 944?

The mounts are different for early vs late transmissions. Not sure if there are adapters to go between early/late but I imagine some exist.

Please search google before asking these questions. Clarks should be the first place you look:

So if I want a trans with low RPM’s on the HI way which year would that be? I know I am giving up some acceleration but my car is mostly a daily commute car on an interstate so I would like the RPM’s lower.

87 924S five speed

The absolute best best for highway speeds would be the 6 speed from a 968, but that transaxle will cost more than most 924s cars.

7K ouch! So what 944 has the lowest rear end ratio?

Look at the clarks garage link I posted above

It would almost certainly be a mistake to put a 944 Turbo transmission in your 84 NA. The taller gearing will not make you happy. 944-series cars always had an LSD available as an option: for your '84, it would have been stamped with the 8Q code.

How would you know if I searched google before asking these questions. I am constantly searching everywhere including Google for all information I need, and ChatGPT. I appreciate your advice. Thank you @walfreyydo . i assume you get a lot of people that you can tell in some way when you have been around for a long time have not searched for something obvious. There is a wealth of knowledge I imagine on Rennlist so it is very useful to ask questions here. This seems obvious. And it seems that sometimes a person will feel the question is better suited to Rennlist, and sometimes Google, and sometimes ChatGPT.
Your message sounds like you are a bit irritated with people.
Thanks again.

@zoo
Would the 968 that you mentioned for the 924 could fit into my 1984 944?
Could you elaborate a bit about if adapters would be needed and what is the cost approximately?
Does it have a limited slip diff?

Thanks,
Robin Hood

Not really.

Asking questions for common available information when reference material is available comes across as not committed to searching and reading - or just plain lazy.

The website provided - Clark's Garage contains a vast amount of information, including that which you seek.

You can always add a limited slip diff to a transmission after-the-fact, but it would cost a fair bit of money. I don't know if you'd like a 968 transmission in a regular 2.5L NA. They're way down on power compared to the 968's engine, so would probably be wanting badly in the top gears. I put an S2 trans in my 924S, and 5th is only any good on flat to very small inclines at steady speed. Forget passing anyone in that gear though. I would thing 6th in a 968 TX would be useless. Not enough torque from a standard 2.5.

Thanks @Jay Wellwood my sentiments exactly

Its difficult to deal with people who expect to be spoon fed information and cant even be expected to read/click on a link I provided after doing a google search for them which does have the answer to their question, just requires them to do some reading...

I learned everything about 944s searching/reading websites youtube and forum posts (and actually working on the car myself, after doing said reseach) and not once did I have to come to others for any basic information that had already been answered or was available on clarks or other websites...because I searched beforehand. I expect the same for others I guess.

Heres my secret: google "porsche 944 <question> forums" and you will find over 20 years of information, most of which has been asked and answered multiple times over on both rennlist and pelican parts forums. Do that first, before posting a question. Read through clarks garage in your spare time (makes great bathroom reading btw). Research research research before even touching a wrench. Come to the forums if you have a specific issue or unique situation that hasnt been answered before.

@Jay Wellwood
I had gone to Clark's Garage the first time someone shared that link. I would not have gotten the link if I had not asked my question here in my case.

So you are explaning something to me that is, I'm sure you intend saying this for good reasons and out of a kind heart, but it comes across that your are assuming I might have not been trying my best and following every lead as it became known. I also don't want to waist my time (just like you don't want your time waisted, but you could just move on). So as soon as I saw the clarks link I went there. Even when I'm asking a question, that can't be lazy and it is even brave of me. It is just another aspect of work. And the complexity of anyone's path thru work is very high since we have billions of things we have learned in our life varied by the unique experiences we all have, and varied even more multi-dimensionally by how we all uniquely learn, and our unique skill set. So really, assuming every one is doing their best (and hopefully allowing them to do it freely and with support and acceptance and in a way that is fun to them) is much more caring and frankly, more accurate. Your position, although commendable in some ways, seems to tread on a persons sense of self-agency. And people hate that feeling. So it also helps people to like you if you assume the best of them.


And why is this even a thing? The very reason for Rennlist is to ask questions. hahaha And it is VERY attractive and very fun that it is even here. It is awesome that we have this place to come together and have the common interest we have. So maybe some people prefer to ask questions here just because it is a community and they want to feel that connect that is not really there with google. Google is just an impersonal service where there is no mechanism for the social factor. When something is attractive to me I go after it. I go to it first and then maybe to something that is less attractive.
Thanks Jay!!
I appreciate your view.

Putting more effort into your own statement (i.e.not being lazy yourself) you might try to come up with a solution that is both better for your concern, the amount of questions being too high, or to many repeat questions, with others concerns, like coming here over going to google for the good reasons I mentioned, I put about 3 minutes into thinking about it and already came up with the idea of having a FAQ that would have the most repeated questions in it. And it could even be comtributed to by members themselves. Then it could be advertised through initial requirement to have people onboard where it is mentioned to them. The idea could go on and on. This way you not only solve both sides concerns you even create MORE community!! Another idea is to make the Rennlist search feature a bit more pronounced with a flashy Title like, please search before you ask, it saves brain waves!! Bring some humor into it. It builds the resolver of knowledge. And you don't have to wait for someone to respond, it's faster!!

People who, and I use to be one of them because I used to be only in my head and not in my heart, mention (or get an ego hit) that they have always done and learned everything by themselves, might just like being a loner. Maybe I grew out of that and like to share my journey, as I Learn, more now.
