    I have a Ford 2.2 Diesel transit motor Home,Manufactured in 2000.
    It has a 5 speed G/box and could do with a 6th. Gear.
    Is there a 6 Gearbox that will fit?

    You need to do a lot more research, you could finish up with a 6 speed box and a worse final drive ratio than you already have:Doh:



    Non technical solution

    If sourcing second hand the best tip I can give you is Mini buses usualy have the longest legs in their gearboxes, Built for cruising:thumb:

    Flat back tipper types have the shortest, Built for pulling carrying power:thumb:
    In the motor home world it seems you take pot luck what your chassis was going to be, before it was pulled off the line to be sold to a converter:Doh:

    There is a simple solution to this on a ducato, it is a 5th gear upgrade, we do quite a few, but not on a transit as yet

    Think you are barking on the wrong tree.

    I've a 2L 125 2005 Transit and my 5th gear is absolultey fine. In fact I prefer this combo than the 6 speed 2.2L MK7 versions and I've driven all variants.

    You may actually have a lower diff ratio which, for vans, can vary depending on expected usage. This can make a huge difference. I think the above post is wrong (though no money placed on this! The final diff is different rather than the gear box)

    Look at fordtransit.org and ask there - some very vanned up experts and they have access to the ford system which tells you what final drive diff you have. This, I guess, would be a much easier swap than a gearbox - as IIRC the gearbox only became 6 speed on MK7 versions and thus loads of differences over yoiur van.

    Hope this is useful (even if incorrect!)

    This is not always the case, council run minibuses often have the lowest gearing available as they mainly do short start stop journeys picking up and dropping off at multiple stops. Our old Freight Rover home converted was just such an example having been a Walsall council owned disabled transport minibus, even in fifth gear 56MPH was near to 4000 RPM! Bloody thing used to drink petrol like a Yankie RV:RollEyes:!

    I would be looking at a diff change before ANYTHING else. The question you really have to ask yourself is would a different ratio diff or 6th gear be pullable by a 2.2 litre engine, or would you find yourself constantly changing down to 5th given the very slightest of inclines, thereby totally defeating the object.

    See........there's a whole lot more to this once you start digging.....

    altering the final drive(diff) ratio will also alter all the gear ratio's.

    gear it up and first may be, theoretically, too high for hill starts without loads of clutch slipping.
    gear it down and first may become nothing but a crawler gear and pretty much useless in normal use,

    thanks for all your advice.

    it would seem that a Diff. change could help.
    But I think I will stick with what I have as it is not a Major problem.
    Thank you all again.
