Pass, lol

If the entire transmission unit twisted bad enough under load where you'd miss the shift, not just a vague linkage.

anyone else notice the line to R is curved, but the line to 7 isnt? does this mean no 7th gear lockout of any sort? hmmm...

I would guess in order to use R gear you need to first release to neutral and then press down to the R gear. That may also be the reason where there is a little gap in the line.

Many manual cars from VW is done like this. Not sure if BMW or mb are like this as well but I guess that is a german car thing.

Misinformation much? If you check automatic gearing you can see that they not only reduce the RPM for cruising beyond a manual but they put the engine outside of it's torque curve. EG the tiny engined Honda Fit cruises at 60mph @ 2800RPMs with 5spdStandard vs 2200RPMs with the 5spdAuto. Or maybe a better example is the RX-8's Renesis. 3000RPM with 6spdStandard vs 2000RPM with 6spdAuto.

The Mustang, Camaro, Corvette, and Viper have had double overdrives in 6spds for awhile now.

If you want, there is probably a dozen articles I can find on the subject.
And pretty much all sports/y/ish cars with standard could use a taller set of cruising gears.

Offering more gears is the easiest way to offer short enough gears for acceleration yet tall enough for good MPG. You are not required to use all of them all the time.

well i used to drive an s2000 so i know about having double overdrives. and yes, during highway cruising it was revving around 4k so it could've used a taller gear. i've heard the same about the miata 6 speed. but it honestly would be a lot easier to just make the 6th gear taller as opposed to adding a whole 'nother overdrive gear. i just don't see the point of having 3 overdrives, why would you need an in between overdrive gear between 5 and 7? i guess that's what porsche is doing but i really can't think of a lot of times that would come in handy.

I don't quite understand what you are saying. You say you understand but you're discussing two cars that don't have double overdrives :iono: but instead had very short 6th gears?

Too much of a drop is bad if they're shifting fast, bad for syncros. Some of the double over drives are basically a regular OD and taller OD with a really short axle ratio. I triple OD I could see being a bit wasteful but it would really depend on the axle gears.

um, what? an overdrive gear is any gear with a ratio of less than 1:1. both 5th and 6th gear in the s2000 are below 1:1. i don't know the miata 6 speed gear ratios off the top of my head but i'm positive it has double overdrives as well.

what i'm saying is, the s2000 had double overdrive but the final drive was a little short, so i can understand wanting an even taller gear. but why not just make the 6th gear taller instead of adding a 7th?

yes too much of a drop is bad when shifting fast, but why would you be shifting fast or shifting near redline in a cruise gear? the only time you'll notice the difference is if you're going 140+mph.

Yeah, the S2000 isn't a good example of a Double Overdrive, it's a very close ratio box and 5th is barely more than 1:1 ratio. Most domestics use a 1:1 gear and they use two gears for OD and that 6th gear can be from .50-.68 or so.

well i like the gear spacing on the s2000 so for a 7 speed, it would make more sense to me if 5th was 1:1 or at least close to 1:1 with an overdrive 6th and 7th, which is why i made the initial comment. but i guess that's not what porsche is doing.

I didn't mean to make that sound like a negative X).

ok well you quoted me and said "misinformation much" so you made it sound like i didn't know what i was talking about. i feel vindicated much!!!

It was more to do with you two saying that taller gearing would hurt MPG. But w/e. I'm passed it.

never said that!:bellyroll:
