What is a 915 gearbox?
Table of Contents
The type 915 transmission was a four or five speed transmission designed and manufactured by Porsche between 1972 and 1986. The transmission was used in the type 911 and type 916 cars.
When was the G50 gearbox introduced?
Drdjet: The G50 transmission, built by Getrag, is solely the type designation for the transmission available on the 1987-1989 3.2 Carrera. Prior to that, back to the early 1970s, Porsche used the 915 and the 901 and 911 before that.
What is Porsche G50?
The G50 featured a hydraulic clutch and was a smoother shifting gearbox than the rugged but finicky Type 915 transmission it replaced. This example is finished in Grand Prix White and has impact bumpers, rear spoilers, a power sunroof, and front fog lights.
How does Porsche transmission work?
In the PDK, the gears are distributed between two separate clutches — hence the name. The odd gears and reverse are connected to clutch I, while the even gears are connected to clutch II. The technology enables fully automatic gear changes without traction interruption.
What is a 911 G50?
Can you still buy a manual 911?
Porsche’s 911 Gets its Manual Gearbox Back You have to think Porsche heard the message from three-pedal fans loud and clear. Thus a 7-speed manual transmission can now be ordered for all 911 Carrera S and 4S models to replace the 8-speed PDK transmission, and at no extra charge.
What’s the difference between 911 and 912?
The 912E has the same chassis as the 911 and therefore handles much like the 911. But with less power and less weight behind the rear axle, the 912E is more forgiving and less prone to sudden oversteer than the 911.
What kind of transmission does a Porsche 915 have?
Porsche transmission type: 915. Original equipment for: Porsche 911 72-86. Description: 4 or 5 speed manual transaxle w/non synchronized reverse and early Porsche synchromesh. Limited Slip Differential: 40%-80% ZF LSD optional equipment. Weight (approx): 123lbs. Oil Capacity (approx): 3L SAE 90 transmission oil.
Why does the 915 have a 5th gear?
Another theory is that having 5th gear and reverse in the end cover was so that it would be easy to change the ratio for 5 th gear to suit specific tracks for the racing versions of the 915 transmission. Maybe both factored into the decision. Like the 901 series, the 915 case consist of three main parts.
What is the final drive ratio of a 915?
The final drive consists of a pinion and ring gear. As this is a transaxle design, the pinion gear is on the end of (part of) the output shaft. The ring gear is bolted to the differential. The final drive ratio is the ratio of the teeth count between the pinion and ring gears. For example a typical 915 final drive has a ratio of 8:31 (3. 875).
What is the difference between a 916 and a 915?
The design of the 915 is based upon, but is not identical to that of the 916 transmission that had been used years before in the 908 racing car. One feature of the 916 that carried over to the 915 is the orientation of 1st through 5th gears.
