shift by wire for vehicles

There are Porsches and Ferraris. I think VW has one also. In heavy duty trucks there is one also. Not sure, but I think it is Eaton. In Europe, you might try ZF. Good luck.

but porshe & ferrari use sequential gearbox not a conventional h pattern mannual not sure abt eatone

Toyota

If you start at this link, you can then follow some of the links from this Wikipedia article, to specific types.

The Ferrari paddle shifter was among the first modern shift by wire transmissions in which there is no torque converter. The Porsche Tiptronic which came out (I'm guessing), in the 70's, used a torque converter and would override the driver at times to prevent engine damage. In the mid-fifties Citroen brought out its four speed hydraulically-controlled transmission, in which the clutch was automatically controlled for shifting (with the shifting done by the driver) and to start out, and stop. The shift lever was not mechanically connected to the transmission, (but operated a hydraulic control unit) and moved through a much smaller-than-usual quadrant.

There are loads of others, with one of the more modern being the DSG, or direct shift gearbox. (See link in Wiki article.)

All AMTs alo have a manual mode in which the driver chooses the gear and the control system does the actuation of clutch and gearchange. There are several systems for the controls of the gearchange:

X-Y hydraulic - on Renault Twingo Clio Trafic and Master, Ferrari 355F1, 360 Modena,

X-Y electric - Opel Corsa

Barrel - Smart

S-cam - Mercedes C-class

You will generally find a different grid on the lever as there is on the gearbox.

One electric lever with H-grid can be found on Alfa Romeo 164 Q-matic whitch funnyly has no H-grid in the box as it is a converter automatic with planetary gears.

There are many many others today. I stopped following this when I went into engine development but in my previous life I was AMT project manager at Renault and we worked with the Selespeed system from Magneti Marelli that you can now find on many cars from Fiat , Alfa Romeo, Renault, Ferrari, Maserati, Peugeot etc.
