Only if it takes you 2 seconds to complete a shift.

Nope, even in speed-shifting the standard NA falls behind because of the extra shift.

so..is the 951 box a posi too??
Getting ready to start on the transaxle pull and checkout of 83 944NA.might be easier to do a swap now and use the $$ on the 951. Thanx Tiger 03447

Some are, some aren't.

Go to "Clarks Garage" sight and look up specifications. It will show which transaxle codes came with limited slip and/or cooler. Lots of great info on that sight.

limited slip is of limited value for normal street driving - in fact if my experience with my 993 is any guide, it's a disadvantage, the LS get stressed making tight turns to get into driveways and parking spaces and it started shedding metal particles, destroying the three differential bearings and the carrier (at about 140K) - the little needle bearing rollers in the differential cracked into pieces causing havoc. I changed two of the bearings (axle) leaving the pinion bearing alone, then the car was stolen so it's not my problem any more.

on my 85.5, the original factory transmission dropped a tooth off the pinion gear - I had some warning, a "sharp" sound from the trans under heavy load for a few weeks before it failed - I don't know (20 years later) whether that sound was the pawl on the clutch or the crack in the gear - when the gear finally failed (on the freeway, in rush hour traffic, in heavy rain), I was able to limp along for several miles until I had to come to a stop, and then trying to get going, the differential locked up and ripped the center out of the clutch (or alternatively, the center was already bad, and it made the clutch skip over the pawls) - at any rate, the transmissions can fail. A second rebuilt, which was not done right lasted a few years before the side plate just fell off, destroying the trans, and the third trans, a factory unit in a box, new, not rebuilt, has lasted me ever since.

So, my advise would be to use a stock non LS transmission and not worry about it. (by the way, I have the transmission from an 87 S available, for sale)

How much are you hoping for?

Not really.

Cant give the link but go to Clarks Garage then Garage shop manual then click transmission information. Scroll down and observe all the different variations available to the turbo, S and S2 models.
Chances are if you find a LSD trans it will be fairly worn out anyway.

6 out of 6 LSD transaxles I have gone through had the LSD worn out and in need of a rebuilt.
