Hi all, recently purchased a 1.6tdci auto only to have the gearbox fail, been quoted 4000 for a replacement as ford dont do parts, dont forget the >3 month wait too!

So My question to youall out there, is it possible to fit the auto gearbox from the 2l? as it seems ford stopped fitting these for a reason and I cant pay that for it to fail again :(

any thoughts or advice?

was,

I really feel for you having your gearbox go. Unfortunately, you're not alone - I've had a CVT auto with hesitation problems and trawled various forums trying to find a fix. I've seen several other reports of gearbox failure. In each case Ford's solution was the same as they told you.

As regards swapping the gearbox from one in a 2litre petrol, the answer is almost certainly no. Modern cars have so much electronics that it just won't work.

Your car has one computer on the engine, the ECU and another one that controls the gearbox, the Powertrain Control Module (PCM). The PCM gets all sorts of information from sensors in both the engine and gearbox and from the readings on the sensors tells the engine and gearbox what to do. The PCM is unique to the engine / gearbox combination, so if you change to a different gearbox, a lot of the sensors will be different, as will be the instructions back to the gearbox. Unless you can get someone to design and build a dedicated PCM, you're stuffed.

You're stuck getting the CVT fixed or scrapping the car.

I did read of someone getting their failed gearbox fixed by an independent CVT gearbox specialist, but couldn't find the link just now.

Links I found on the Honest John website to gearbox specialists are as follows:

Hi was,

We have just had a similar problem with an 04 1.6tdci CVT transmission malfunction. The car has only done 48000 miles and we have had it from new. We are told by the ford garage it needs a new gearbox. The part would cost 3500 plus labour. Because of delays the have referred me to AI premier transmissions who can repair. A1 say it could be the torque converter and if both need replacing the cost would be 1900. hope this helps.

I know this is old, but what where the symptoms of the Gear box needing changing, my car has been a bit sluggish and today i drove it for 2 minutes before getting a "Transmission malfunction" and turning back home. I've just tried to car again and now it wont even move, I've tried reverse, drive and nothing.

sorry if i sound like an !Removed! but fords auto boxes are quite frankly weak and all the car mags and reviews tell you to avoid auto boxes onlly the vw derived box were any good sorry to hear the box has gone unless you really need it i always advise to buy manual they are far stronger easier to change my stepdads vauxhall was the last auto box he got and between software issues and the box eventually going i can say they arent any better mega expensive to replace and a pain in the rear to fit as it needds the software checked etc

Sounds worryingly familiar! ...

... I've got a 2006 Ford 1.6 TDCI Diesel CMAX Auto which I brought new and it's done around 46,000 miles. Last week my wife drove our car along our road where we live. It travelled 100 meters and then came to an abrupt halt. (as if it had hit something, but hadn't). A loud sound heard under bonnet like a pipe being pierced was heard and then loads of gear box oil everywhere. It was fortunate my wife was not traveling at speed with someone on her tail! or somewhere remote. The car is currently at a garage for investigation. We deliberately sourced an auto new and they were described as the 'golden unicorn' among CMAX cars. Although I reckon 'if' a new auto gearbox is needed, could one not be sourced from one of its relatives like the Ford Focus? The CMAX is surely only a larger MPV chassis with similar or the same Ford parts?

Whatever the reason for this major malfunction I guess it's going to cost big 's.

Colleague at work had a Ford Focus 05 manual and had to have his power steering pump replaced 3 times at a main Ford dealer ... he then gave it up. He did get 30% of repair work as compensation. But main dealer prices still cost him a lot overall. Mine is at an independent garage but may involve a gearbox specialist to fit.

I'll await garage feedback then check out links given if needed and Ebay

It appears that at some stage after 2006 (not sure when, others might know) Ford realised the 5-drive CVT auto gearbox was not up to scratch so opted to introduce a 4-drive CVT auto gearbox instead. I believe this is not compatible with Mark 1 C-Max cars (older 2006 and older models), because of gearbox chassis variants. I'm not sure if the 4-drive CVT auto gearbox is any more stable either! ... I guess only time will tell. As far as I'm aware C-Max cars with manual gearboxes are fine, it is the autos that are the issue. I did consider whether the cousin the standard Ford Focus auto gearbox might be compatible, though have been told from a number of sources this is not the case. I wondered if the 2L gearbox might fit a 1.6L from another C-Max but apparently the "powertrain" PCM is set up for this specific 5-drive CVT auto gearbox is unique to the older C-max cars, alas not the newer gearbox. I have since found a 5-drive gearbox and torque convertor, incl delivery for 1,500 from a C-max that was involved in a crash from the rear. the dilemma for me however, is do I get it fitted or get a different car altogether. If I get the older 5-drive gearbox fitted, I may end up with this one dying on me in the same way my old one did. I think I'd would lack confidence driving in a car that is not as safe as it should be. My last C-Max auto came to an abrupt halt when the gearbox/torque convertor went ... could of been fatal if my wife had not been driving on a quiet road.

the problem with these is mostly not the box but module to module communication on the can network. the repair involves a couple of sensors, a modified wiring loom and some module programming work. i will be happy to help anyone who can get their car to bradford. i will be busy until friday but please feel free to pm me your contact details and i will call you then, regards steve
