Ive done a fair few searches now on google and forums and I cant seem to locate which exact gearbox I have in my car.

2012 Focus 1,6 Ecoboost 182. - 6speed manual.

Sound searches suggest it shares the same box as the ST but I find that hard to believe, and then others suggest a slightly different box with different torque ratings...

Where will I find this information - ETIS?

It is called the B6 gearbox, or 6MTT250 (rated up to 285Nm). This is used on the 1.0 125PS, 1.6 150/180PS and 1.5 150/180PS Ecoboosts.

The ST has a much higher rated, heavier gearbox, the MMT6 or 6MTT450 (rated up to 450Nm).

The ST has the same gearbox as the 2.0 TDCi (in all power outputs, 150/163/185PS).

Excellent, cheers for this bud! - I thought that would be the case. I've been looking at getting my car "mountune'd" but initial figures (no longer on the website from what I can see) suggest it will be too stressful on the standard gearbox.

Damn.

The 1.6 Ecoboost already puts out 270Nm on overboost.

The funny thing is that the Mountune MP200 package for the 1.6 EB is warranty friendly, despite putting out 320Nm.

I guess the box can cope with more than the design limit or it can just cope long enough not to fail during the warranty period, lol.

The Ford/Getrag 6MTT250 gearbox is rated at a maximum torque of 285 Nm and not 250 Nm.

So it is, lol.

Naming system makes no sense...

6MTT450 is still 450Nm though.

The maximum amount of torque a gearbox can handle is calculated by the manufacturer using a safety factor. This safety factor depends on technical design and material of the gearbox parts.

Based on technical documentation the Ford/Getrag the 6MTT250 gearbox has a safety factor of 1.3. This basically means that the 6MTT250 gearbox should be able to handle 370 Nm before breaking down.

 

Thanks guys! Appreciate it!

Could You advice then.if I have a 1.5 tdci 120km B6  gearbox what maxium  Nm schould I use for a remap ECU.I have a heavy foot and also  the car shcould be ready for long distance  driving at constant 190km/h speed.I have 1.000 km waiting for 2,500km and going to remap the ECU.

Been a while since this topic was started but I want to upgrade the gearbox on my Fiesta 2009 EcoNetic which will go up to about 270 ~ 300 bhp and >450NM torque. While browsing the web i noticed the Ford Focus MK3 TDCI 2.0 ST has a pretty beefy gearbox. From what i found online it looks like it can fit the block which i have (the DV6 engine). Do you guys have any info on this that could help me please! Cheers
