944S Transaxle (transmission) For Sale

80-90,000 miles. No issues. $600 plus shipping. stronger than a NA transmission. same gears and bearing etc. as the Turbo trans but with NA final drive ratio. email [You must be registered and logged in to see this link.] for pics.
Thanks.

Would it be an open diff or limited slip? I'm guessing open but there's no harm in asking.

Its an open diff. There are a few out there FS around $400. Depending on your application and power, you may not need an LSD.

Just F.Y.I., the ring and pinion and ratio isn't the same as the early n/a. The early is 3.88 and the S & S2 is 3.875. The 3.88 is 9:35 and the 3.875 is 8:31. The late shares the same dimensions as the turbo which makes it larger in diameter than the early n/a. The S & S2 will take the same torque as the turbo but the early will not.

Hey guys, I would be keeping this trans as a back up, but it has too much gear for a road race car. I have purchased a turbo trans for that purpose. This would be a great street trans due to its strength and gearing. It is crated and ready to ship!
Thanks, Gene

just wondering if you still had this tranny, if so what is the code on it. I fried my early na trans and will be looking for one in the next few months when money comes in. I am hoping to find the turbo trans.

the 944S trans has the same heavy duty gear set as the turbo trans but has a different final ratio. I still have it. Gene

I have to rip into my trans to see if the fifth gear is still good. I had to drag my car after the trans went so I am hopign it didnt do much damage. Can you do the 5th gear swap and still hit the top speeds or is that just a turbo trans. I understand teh gear sets but I get confused on what final drive does.

how does the numbers affect anything?

The 944S was a 16v engine that liked to rev a bit more than the 8v car (like yours). The individual gear ratios are the same with the turbo, but the final drive ratio (in a Camaro it would be the rear end) is numerically higher. This allows the engine to turn at a higher RPM in each gear for a given road speed. For a street car this might be something you would like for acceleration, but not for gas mileage on the highway. Jump in the new Camaro and you will probably turn 1,500 RPM at 70 on the interstate (just a guess). With a 944S trans you would be turning more like 2,500 RPMs (again just a guess).

Here are some comparisons. All these ate figured with a 245/50 16 size tire

early 944 (or late w/early ratio 5th)
55 MPH @ 2000 RPM
193 MPH @ 7200 RPM

stock 951
55 MPH @ 1950 RPM
196 MPH @ 7200 RPM

951 w/ early 5th gear
55 MPH @ 1800 RPM
223 MPH @ 7200 RPM

The RPM's are close but not exact because I picked them off of a line on a graph on my ratio spread sheet. The 951 has slightly closer ratios
