Having had my share of diesel automotive problems for the past 2 months, and knowing Ford Australia is a bunch of clueless cretins who solely rely on a computer diagnostic tool and no actual mechanical skills, I'd say sell the bloody thing and buy a reputable brand like Toyota.
Ford had my car for one month. Claimed it was the PCM. It wasn't - but still $2500. Then said it was injectors...which it wasn't after $4000 (but getting a refund of $2500 for the incorrect PCM replacement). After one month, they shrugged their shoulders.
Yesterday took it to a transmission shop who changed my ATF. Still pink (after NOT having been changed in 127,000 km) and very little in the filter - no swarf, no "glitter". Now it drives absolutely perfectly with no shudder between 2nd and 3rd as before (which Ford said was a PCM and injector issue because of the P0176D-II code). Cost was $560 for a full flush and filter change (these are a wet clutch transmission, so no torque converter). Whilst I am pi$$ed at Ford, I must say for a transmission that has - by my fault/sheer absent-mindedness - missed not 1 but 2 60,000km transmission fluid changes that for it to have held up and still be reasonably non-affected is marvellous testimony to Peugeot

(see, French do make good things). I drove the car 82,000km last year alone!
Ford Corporate (Aust.) has now been informed of the behaviour of Ford here, and we will see what happens. They owe me a LOT of explanations and MONEY (more involved than just the parts being a work car)
I feel a Toyota or Honda in my future...
