sierra 5-speed gearbox not type 9?
hi all
as I know some of you are great connaisseurs of Ford Sierra mechanics, I would ask the following:
- today I saw a Sierra 2.0 CLX with DOHC engine with carburetor, but the strange thing (for me) was the 5-speed gearbox had the reverse gear not as
usual in type 9's (up & left) but right & down just bellow the 5th gear.
I ask: is that the type 9 with another gear configuration or it is another type of gearbox? if this last case, what gearbox is it?
thank you very much in advance.

MT75 is stronger than Type 9
Bellhousing is fixed and box is bigger
Ratios are not as close as Type 9
May be better suited to 15" wheels and 3.62 diff

As Snapper says, though a 3.92 diff is also used by many who run the MT75.
Bellhousing is integral rather than separate, & bolts straight up to a Zetec Blacktop (probably does the same with other Ford engines)
MT75 is wider than the type 9, but if you ditch the gearchange 'saddle', (as many do to fit a quickchange instead) it's actually
shorter than the type 9.

The main disadvantage of the MT75 is the lack of aftermarket gear kits.
The standard 1st gear in most production gear boxes is designed for towing a caravan up a gradient from a standing start by a car weighing over 1 1/2
tonnes. In most kit cars that is not the case and 1st gear just lights up the back tyres and you end up snatching 2nd shortly after moving off. By
simply changing 1st gear you end up with a much more drivable car and there are several suppliers who will do this with a type 9 for not much money,
you can even buy the kits and DIY if you know gearboxes and have the tools. As I understand it the only gearkits available for the MT75 are very
expensive Ford Motorsport ones.
Having owned 7's with standard ratios and ones with close ratios I know 100% which is best and for that reason alone I would never fit an MT75.
