5 speed vs. 6 speed gearbox comparison (pics)

OK I've found some 5 speed gearbox pics but I still can't find any 6 speed gearbox pics yet but I'm still trying
So which manufacturer do you think this 5 speed is made by?

I'd say it's made by Getrag, just like the 6 speed. If fact, I am pretty sure that's the case.

I seem to recall reading that the 5 speed box is sourced from Volkswagen.

Incidentally....a read of the manual shows that the 6-speed's gear ratios for 1st and 2nd are DIFFERENT when in the 2.7 versus the 3.4, which I find interesting.

(3.67 and 2.05 for the 2.7, but 3.31 and 1.95 for the 3.4)

3rd through 6th are the same.

Also, the final drive ratio of .82:1 for 6th gear isn't that much taller than the .84 in the 5-speed.

I liked the 5 speed in my 2.7, by the way.

I've got a little surprise for you. VW and/or Audi don't make transmissions. They source them out just like everyone else. That's sort of a specialty part. And they have also been known to use Getrags.

I had once heard that they were made by VW, and another time that they were Japanese. I asked the Guru, Scott Slauson, and he had this to say:

The Aisin Seiki is used in the 997.

So what do these ratios signify? Also what's a 'good' or 'bad' gear ratio...

There are not many companies out there manufacturing transmissions. I say Getrag or ZF. A real dark horse would be the people in California "Butfoy" that make gear boxes for lambos, Vectors and others based on the old series SD-2 ZF.

Gear ratio - Wikipedia, the free encyclopedia

The gear ratios will contribute to how quickly a car can accelerate and/or how fast it's top speed will be. My understanding is that the gear ratios in a Cayman S vary from those of a 911 in a way that makes the Cayman a bit slower to 60mph than it could be, with different gear ratios to avoid the problem of having a Cayman be too close for comfort to the 911.

The new Nissan GT-R is a great example of creative gearing. It is geared to accelerate very quickly to 60...and REDLINES at 186 mph. They do this to keep up with the 911 Turbo which has the same amount of HP but 400 pounds less weight. The GT-R probably NEEDS the auto/manual clutch gizmo to shift quickly enough to take advantage of the gearing. My brother's 997 TT is very hard to nail in first gear without banging against the rev limiter.

golfguy: From the gear ratios reported above, the 2.7 Cayman has "lower" ratios (higher number = lower ratio) for the first two gears, giving it more grunt (applied torque) in those gears. This may be partly why some who've driven both back-to-back reported being surprised that the 2.7 was so quick up to 60 mph or so.

When the '06 CS came out, it not only had higher gearing in the first two gears than the 997, but it also had higher gearing than the '06 Boxster S, which had 280 hp at that time.

One way to increase acceleration of the CS would be to lower the gearing some, but that doesn't seem very simple. I've not understood why the gearing of the CS is as it is (the two top gears are both over-drives, for example), unless it was to help maintain the separation between the CS and the 997.

Hi again !

There is nothing to find except "made in Germany", "VW" and "Audi" on the 5-speed-gearbox.I did a conversion to 6-speed from a Boxster S `07 and the 6-speed-gearbox is definitely made by Getrag.But the 6-speed-gearbox has a very big disadvantage - the weight !

Best regards !

i wonder if the bellhousing is the same bolt pattern as v.a.g ?
it looks it !
possible 1.8t / other v.a.g engine's in the future !
even the old water cooled flat four (i used to rebuild these when i was a apprentice !).
thats another thing - is the porsche bottom end similar to the vag water boxer ?.
i know they share a lot of stuff !

Do you have any pics of your 6-speed gearbox?
