MC Shift – What type of gearbox is it really?

[CatmanV2]

Neutral in a tunnel. Rev. Select gear. Off you go again.

Ahh, happy days

I have to say I've been through a couple recently in the Ghibli. Quite a laugh shifting down a few

In my experience you can select N at speed and then pull the paddle and it will select the appropriate gear. Only at very low speeds in traffic if I “childishly” select neutral to “rev a little” and am close to stationery, I may have to apply the brake to select a gear.

Yup, that’s exactly what I would have done

My preference in a tunnel is to slow right down, shift into 2nd and snap into 3rd at about 7500rpm

There's a lot of discussion and I am happy to be corrected but I believe the informed opinion may be expressed as 'They share the same basics, but there are so many differences that you really can't call it a shared engine.

C

If you go by the engine reference, the are all F136 engines, with different letters afterwards to signify the internal / external component difference. For example, the engine in the 458 Speciale is F136FL whereas the engine in a Granturismo MC Stradale (2 seat) is a F136YK. The version fitted to the A1 GP car was just called F136.

Given that a significant number of parts are interchangeable, that the cylinder block is the same casting, it would be fair to say it’s the same engine type, but it is not the same engine. The Maserati version sounds much much better anyway.

We used to do it on drives past. Select neutral, rev it, pull for a gear.

Works less well on a ZF equipped GT I confess.....

I've often wondered if we could do this, but I've never had the guts to try it!

Yes, think its probably under 5mph or similar you have to apply the brake first.

Don't try it on the ZF. Look at where you have to go from D > N....

[Motorsport3]

Well sort of....

The engine isn't (really, AFAIK) and the box is Graziano from memory. Which is a bit like saying that my Bentley (or Granturismo) had a Hyundai box

C

And Graziano is also the noise it makes when the shift doesn't quite go as planned!

 

[Ebenezer]

I tried to simulate a racing start once with my ZF. ie foot on the break while building revs. I did the rev gently as I didn't know what to expect and got a rather nasty "graziano" so abandoned that experiment rather quickly! I wonder what's different between the GT S ZF auto gearbox and programming to the 4.2 one, so that it allows racings starts without rogering the gearbox!

It's direct?

That's for the ZF? Great to know. I should check the manual but it's deep in the depths of the boot still

No. That's the MC.

Now I was convinced that you had to go through reverse to get to neutral on the ZF, but having just checked the manual, I was totally wrong, so I can't really see any reason you might not want to go D>N rev it and back to D.

I wouldn't do that at speed. I imagine the torque converter might not be happy about it.

 

[azapa]

fun fact: you can bump start a MC Shift car, ignition on, good push and a couple of right paddle clicks and off she goes. Ask me how I know, some other time.

No, pretty sure I wouldn't want to

Actually good to know!
I've only been caught out once and had a new battery since, but worth remembering.
