Getrag Gearboxes

[Ten Four]

This has always puzzled me....

I know the following have the 6 speed getrag gearbox:

R34 GTR

M3 EVO

E39 M5

Supra, Non VVTI/VVTI

Mitsubishi GTO

Are there others that use it?

Anyway, are the boxes all the same? Ie interchangeable... Someone know? Cheers.

no?

No they are not interchangeable, and in most cases are completely different gearbox designs between different cars. Getrag gearboxes usually have an integrated bellhousing, i.e. designed to fit a specific engine block and can't be removed. Because of this, even gearboxes of the same model, e.g. Getrag 260, will not be interchangeable. The Getrag 260 was used in VS (series 3) / VT / VX / VY V6 Commodores, Beamers and Jags...yet they are not intercompatible between the manufacturers (unless you wanna do some cutting and welding conversion work).

Your Supra uses a Getrag V160 or V161, for reference. I am not certain if this gearbox was placed in any other vehicle, but I doubt it.

Getrags also have the wonderful advantage of being European and therefore rather expensive to repair.

From memory the S15 Silvia used a Getrag Gearbox as well.

[old mate]

the only one made from glass?

Lol.

S15 uses an Aisin 6 speed, which has an integrated bellhousing despite being much the same gearbox used in the Lexus IS200, Mazda MX5, Mazda RX8 and Honda S2000

Aisin also produced the 6 speed used in the VZ Commodore V6.

Also, the S15 gearbox is not that weak - two bathurst 24 hour races, several endurance and we've never broken one. People just like to drift with triple plate clutches and 250rwkw through a drivetrain that was originally designed to handle 180fkw~ from factory in a lightweight sports coupe...

^^ I see,

But you still get ppl doing 5 speed conversions.

[Birds]

Yeah, not a fan personally...I've sold heaps of S14 gearboxes to S15 owners who are under the impression the S14 is much stronger. I don't know where the consensus came from...I disagree, but am happy to take their 6 speed off their hands.

In my opinion the Aisin is a much better box all round. The only advantage of the S14 box is that you can install a PPG gearset in it. In standard form though, it's still just a small sports sedan gearbox and nothing that I'd want to go drifting with anyway...let alone downgrading retrograding my S15 and losing an overdrive.

ya but for track purposes, 5 speed is much better supposedly...even same with the 34 gtrs....they convert to 5 speed for better gear ratios and power along each gears....

[Birds]

Well that's personal preference, but I don't see how a close ratio box that retains an overdrive could be considered undesirable for track work.

There's a cheaper way to make the r34's move a bit quicker than having to convert to 5sp.

I see...

I would have thought the same as you Birds.

The 6 speed in the S15 seems very good.

[xximpaktxx]

my st170 focus has the getrag 6 speed gearbox

[Birds]

Has "a" Getrag 6 speed...your focus uses a transaxle which altogether is very different from the rest of these RWD platforms...the Calibra Turbo also used a Getrag 6 speed transaxle in AWD form.

And look how well THAT turned out...lol

[Birds]

Hahaha well, transfer case aside, the gearbox isn't too bad

More of a cruiser than a performance vehicle though. I'd never run insane amounts of power through one of those cars.

Depends 'which' 6 speed you're talking about.

I know there's a 420G used in the BMW E39 which is a gearbox for RWD. The 6spd 466 AWD transaxle series is in lots of Porsche's, Audis and the GTO, the 448 6speed AWD transaxle tends to get used in the upper end Porsches. For what its worth, they are capable of holding big horsepower around 450 or so stock and after that they do need some (relatively inexpensive) bracing modifications to the housing and transfer cases, if you do manage to break one they do cost a veritable fortune. Most people break them because they're terrible, the boxes themselves are actually quite good!

In my experience a lot of them aren't interchangeable if that makes it any easier for you. The very hard way is to contract Getrag and be prepared to go slightly crazy in the process...
