I can't find where edo is comparing the T56 to the Getrag?

I think the point edo is trying to make is that the T56 in Brian and Lachlan's cars have a completely different feel to your run of the mill T56.

This entire thread is about the getrag not the T56. In any event do what you will to the gear shifter, bottom line, it is still an ordinary T56 truck like trans. :ermm:

If we are lucky enough to get the GETRAG in the new series II Falcon this would always be a far superior solution to the problem. :thumbsup::ermm::ermm:

If we get a box that can deal with the sort of grunt Brians & say the C & V car can make then the world will definately be a better place.

Id be happy with a box like Brians...I might be happier with a getrag...stuffed if I know...it doesnt even exist.

Nice rumour Peter ... time will tell that it is just that. Nice try to push the Getrag name again :kissmy:

Now I don't know what ratios the Getrag can be produced with but I know this: the two versions that are available in the Supra, (and M5) are not working ratios for the T6. FACT !!!

And this is why ... The Ford driveline will not tolerate any higher diff ratio than 3.23:1. It is barely able to cope with the 3.45 currently used in the T. To achieve the same top gear as the current T you would need a diff ratio of 3.08:1. I can see the flexible drive being cut to pieces pretty quick, especially when any mods are done to the engine. The gearbox is not the only weak link in the driveline.

My opinion anyhow ...

If Ford go to a six speed manual I'll be putting my money on a T56 - but it will be a "new" box, with different internal ratios than anything currently in the Tremec range. I will stick my (very long) neck right out here and suggest that the ratios will be very close to what we have in the TR3650 (in AU T3, not BA GT) but with the extra cog slipped in at the fifth gear position. Something like this:

3.3

2.0

1.3

1.0

0.8

0.62

Or maybe they'll get Getrag or ZF to build a box with those ratios ... at twice the price??? Oh look, there goes another one now!!! ... a flying pig!!! :lol:

Well you may be proven right in terms of Fords final choice in terms of the new gearbox, I guess it will ultimately come down to final production pricing. :(

Ford source parts from all over the planet and the new auto trans will come out of Europe so it is more than possible that ford are considering the Getrag Transmission.

And when it comes to ratios do you think that the Germans can only produce one set of ratios? I just hope that the rumor is true, though it does sound to good to be true. What could be better than having the worlds best 6 speed transmission in the BA falcon? :nyaah:

Traveling at speed in reverse would be quite scary I think. Kinda like doing top speed in a fork lift, everything seems to get out of control and you start over correcting yourself.

Except Brians car isn't factory, and the original post was about a replacement gearbox for factory cars. Ford won't match a gearbox spec to the aftermarket whims of people like Brian.

The Brian's of this world are always going to have to look at upgrades to areas such as driveline when making the sort of mods he has to the engine and he's done that, but we're talking factory spec here and I think you've forgotten that whilst arguing the quality of the shift in Brian's car (which no one is doubting). Ford are not going to put an aftermarket gearbox such as the Mal Wood-modified T56 in factory cars, the cost would be prohibitive - full stop. If they did, what would Mal Wood do besides service such gearboxes? It's to his benefit Ford throw in 'on the limit' drivelines into cars such as the XR6T which are undergoing such large performance upgrades. It'll be a factory T56, TR3650 (something that's off the shelf from Tremec as they do several variants of each), or a factory something else like a Getrag. They might decide to stick with the T5 for all we know. FPV are a slightly different story, they might decide mods to an existing gearbox are worth the extra cost.
