That is one amazing piece of mechanical engineering. I'm still trying to figure out how that thing even works. I'm also thinking that it might be interesting to see if a sequential shifter could be made using solenoids so that you could use paddles. Where's Mueller when we need him?

Very cool! It looks as if the solenoid is for the side to side translation (pre programmed) and the fore and aft is given by the person. That would take some time to design.

Didn't the MR2 Spyder come with one of these?

A sequential shifter is really only for race cars and wouldn't be very good on a street car.

you can use a barrel with a machined groove to run the gear selector.
the barrael rotates forward or backward to change gears. |

Yeah, paddle shifters sounds like a great idea, for a racecar. I think I might put my ME degree to use in a couple years if I decide to build a race-914 and get some paddles, but as for a road car, it'd be more of a pain.

Wow, that's crazy. I can't believe he can do all that at the shifter, with no mods to the trans. (if I were to attempt something like this I'd put the mechanical bits at the trans and only use one cable)

Tony,
You can design a sequential shifter if you already have a cable shift set up by using a linear cam to translate gate and selector motions. It's not real complex (think motorcyle, though they use a drum). If you have a shifter rod, then it becomes much more difficult. There's also this one. http://www.takakaira.co.jp/performance/ike...eya_manual.html Andys |

But unless you are only racing, it's a total pain for a street car. OK, coming to a stop, make sure you go through each gear to get down to first.
Cool hardware though, but no good on a driver. My friend Martin Arnaud said he tried driving a (barely streetable) track car with sequential shift on the street and it was a total PITA! |

I was searching for Porsche shifters because I want to rebuild my shifter. I'm planning on a complete ground up design similar to the modern Porsche cable shifters. Then this thing came up and I was stunned. Amazing piece of work. I think I'm still going to stck with a normal H-pattern though.

I wish the honda link would work, we must have killed it.
Forgive my ignorance, but with a sequential shifter (of the manual variety IE: without solenoid) the shift lever doesn't return to center does it? If it doesn't than one of these would not be too difficult with make utilizing a cam as stated above. |
