Hi all,

I have been running almost without issue a 115PS 2.0TDCI 2006 Mondeo mK3 since the start of 2009 and due to some muppets managing to dent pretty much every panel and even tear the front bumper I now find myself with an additional car to use for panels.

The car I have purchased is a 150PS 2.2ST TDCI 2006 Mondeo MK3 with about 130k miles. While I have it and before I sell it off to scrap (oil or diesel over top of engine around injectors and sprayed over everything in front and also engine management light and coil lights on permanently) I want to know about the gear box please...

I believe the ratios for my MTX75 at the moment, the MMT6 in the ST and the MMT6 if on mine are *attached?...

...Can't seem to add photos or pictures or insert any form of html or bbc table?

Any way this has wasted a few hours of my time when I could have been sleeping so really annoyed now, it used to be easy to post and include information in here

Back to my question, um, something about gearboxes, nothing wrong with mine, only done 105K miles and at about 90k I took it apart and cleaned it out and replace the magnet though it turned out to be clean anyway considering the age. As far as I can tell there is nothing wrong with the MMT6 in the donor car and I thought if it was simple enough I would swap them over however I am worried that the MMt6 is no good after reading about it in here.

Any advice please as to whether it is worth it and if I was to go ahead, can I just swap the gear box, cables and shift handle or would swapping them involve any work to the clutch/DMF, bell housing or drive shafts in anyway?

Many thanks for any advice,

Cheers.
D.

The MTX75 will have a cable driven speedo pickup, the clutch will be different

and the 2.2 diesel will kill it and the clutch very quickly.

The 2.2 clutch / flywheel is stronger than the 2L versions.

Not had an issued with the MMT6 gearbox.

Sorry, I might have written my question too poorly - was very tired by then..

I am keeping my bog standard 115PS 2.0L TDCi

I bought the 150PS ST just for the panels and then chucking it to the scrap man unless I can find anyone who wants to buy it for bits.

I was thinking that the MTT6 might go in my 115PS and save me some pennies on the long runs we do every so often (we can quite happily sit with Cruise at 67-73mph for a couple of hours at a time without touching a thing).

I have a relatively brand new clutch and DMF both direct from Ford in my 115ps so won't be changing them as I know they are good for 100k or more so they are staying. The Fly and Clutch in the STI can not say anything about - I saw some sort of receipt of work from some Clutch 'specialist' *cough cough* - I might be wrong about what is in the ST and it might be new top notch kit but I wouldn't bet on it.The speed sensor is not an issue as my motor uses the ABS ring as a speed sensor.

Hopefully now I am clearer and I apologise for any confusion in my original post so here is my question:

Can I have my standard issue 2.0L 115PS TDCi engine with its original 115PS DMF & Clutch and fit in the MMT6?

Many thanks again for your time and patience with me

The 6 speed actually uses more fuel not less. Your 115bhp car will struggle to pull 6th,

well not exactly struggle but it will use even more fuel.

I did some tests with a 130bhp 6 speed, 40mph in 4th used LESS fuel than 40mph in

5th. Even though the revs dropped in 5th and it pulled along lovely, the actual throttle

position was at 18%. In 4th gear the throttle position was just 9% with a reduction in

fuelling also.

The torque required to pull 5th gear at 40mph was obviously above what the engine

produced at a low throttle position. So the ECU pumped in more fuel to increase the

torque. Someone posted a link to a site that explained the throttle on a diesel is

actually a torque tap, open the tap for more torque.

Unless your journey's are long and above 100mph it wont be worth the swap, even then

i doubt its worth the effort.

Cheers Purple. Saves some time as well then, Thank you.

Sell the MMT6 box now and you will have more than enough for a new MTX box

if you ever need one.

Lol, might be able too, problem is I am in a car park so would struggle with supporting the engine but cheers for the suggestion.

If it's diesel over the top of the engine then possibly the flashing glow plug light might just be a simple leak....
