Gearboxes

[ToddM]

Hey guys, just wasn't sure and wanted to ask here before a potential purchase - would a 2.0 HDi 110 S have the longer ratio gearbox?
Many thanks! A quick reply would be appreciated!

[Bailes1992]

Longer gearbox than what? A Morris Minor 1000?

In which case, yes

[Doggy]

Yes, approx. 31 mph/1000 RPM.

[lozz]

Yup 110 has longer ratios, towards the 90




Behave your self sam he was asking a question about a peugeot not A Moggy thou

[Bailes1992]

Are the clutches different between the 90 and 110 then?

[ToddM]

Thanks guys!
As far as I know the 90 is solid flywheel and the 110 is DMF, no? Thanks for the quick reply again, one more question though: Is it the same box as the 136 then? Also will it return better MPG than a 136, even if the 136 is decat+defap+remap?

Yes.

Yes, same box - 1.9XUD / HDi 90 = BE3 or BE4 gearbox: 2.1XUD / HDi 110 / 136 = ML5 gearbox, (probably to do with torque capacity).

Even with decat/defap/remap a 2.2 will burn more fuel than a 110 - (you don't get owt for nowt)

I typically get about 44 mpg, but for a 'fair' comparison judge it against something of similar performance.....

Thanks, doggy! Performance would be great, of course, problem is my gran's just had an accident and she may need a hip replacement (which with the NHS in the UK wouldn't be a problem.. try it in a post-socialistic Bulgaria) and we'll need to save up some cash on the side, I'd really love a 2.2 and all but can't afford it - family should always come first no matter what. After all, you'd be kind enough to lend us the dogmobile sometimes, right?

the 406 could do with an extra gear i think that would improve the mpg a bit.
But the gearbox is one component of a car which i simply find unfathomable i understand how to put them into a car ok, but the internal workings its all mathematical witchcraft. It must take more work to design a gearbox than an engine.

[steve_earwig]

No, not really - it was all done years back by trial and error. Things have probably changed slightly due to computer aided design but I'm sure PSA put a hell of a lot more work into designing the HDi than they did in upgrading the ML5 to ML6.

[Doggy]

I have wondered about this a bit - would an ML6 be better? The higher top gear would be welcome, but the closer ratios may not suit everything. The few diesel 6-speeders I've driven need them because of the very narrow power band that small, high output engines tend to have. I like mine as it is. Bring back overdrive?

Disco's buy-sexual C5 may convince me otherwise......

Well my uncle's done a transplant of an Insignia or a Vectra box in his old shape Zafira 2.2 and I gotta tell you, it goes like stink. I mean it has other various mods but the gearbox makes a massive difference - you can always be spot on where the torque is. You can still stick it in 5th then 6th and forget about it but you know what I mean

[FarmerPug]

My 1.3 gearbox mated to the 1.6 gearbox feels the same as before, although it seems to make much better use of the power than the old 1.6 gearbox did.

[steve_earwig]

Bring back overdrive?

Yes please!

[highlander]

I like the gear ratios of the gearbox in my 2.2 Coupe - it's just that it could do with an extra gear on the end so that I can cruise at 70 MPH with the engine running at (say) 1,800 RPM, not the 3,000 RPM it currently does at that speed in 5th.

It would improve fuel economy.
