Hi all, second problem with my new 24v cossie (the leak turned out to be the thermostat pipe ballooning, all fixed).
Autobox 3-5 seconds engaging D, and quite noisy in low gears (sounds like a jet). However, drives fine, but once done 30mins+ journey, then stops, has trouble engaging D (didnt do it at all last time, had to put it in 1). Then it judders when pulling away, no power until 20mph+ then all is back to normal.
Had automatic expert (Automotive Automatics) look at it last week, he said whining on take off is not major problem, fluid is ok, get it in for a service £130+vat
Time to start saving for a new box? Any tips on reasonable prices? Should i take it off the road until fixed??

I'd look out the black tie, it sounds rather terminal 
Whining and a long delay on engaging Drive indicates
worn out internal components, something a service won't
really fix. Start saving now.

An oil and filter change seems to have helped a lot of people with various problems, try that first, you might be lucky.
Try and get an OBD scan done to see what problems it shows, might just be a solenoid needing replaced
If you need another box i'd try a second hand one first as I couldnt justify £800 worth of new gearbox in a £2000 car..
have a look on ebay, theres the odd one comes up or if your'e really keen buy a whole car 
An engine damaged 24v Ultima sold last night for £123 !! you'd get a reasonable box hopefully and make some money back on the parts

But then theres the fitting! 
A tad beyond the home mechanics capabilities.

May not be good I'm afraid. Mine has no power in 2nd gear and I lost D a couple of months ago, I to have to manualy select 2 then into D when it engages. I also have the turbine noise. Funny thing is, when it is cold and on start up, it behaves fine, then 20 mins later it starts to go bad. An OBD revealed an incorrect ratio in second, so thats that screwed then and I am saving up to get the box done. This is where it gets interesting for me. My local guy is ex-FORDS and is quite at home installing gear boxes (not re-build or recon, just fitting) and has quoted me £150 if I want to find one myself. He was quoted £750+VAT from his contact at Fords for a complete new box and £750 all in from is box specialist for a full recon/fluid/filter job. If that is any use to you.
Other than that, as above, get an OBD done ASAP then make your decisions based on that.

hmm, thats what i thought, sounds similar to mine. i am going up to the Scottish Meet this weekend hopefully, might be able to get a scan done there?
£750 + VAT would be fine by me, i got the car on the cheap (thought it was the leak he was worried about, the g/box wasnt playing up or making noise when i collected it!!) so happy to plough a bit of money into the g/box. love the car, and otherwise everything works!!would he do mine for me if i ask nicely?
is it worth £150 to service it now, or wait until the scan?

ps just drove home, engaged after 3 secs (not snowing now!!), drove fine up and down gears no probs, got home, wouldnt go into drive, but quick into 2, then also quick into D
also, going around a mini roundabout at 15mph funny judder from rear end again??
methinks i bought a dog, woof woof 
could not having a cover under the engine bay be causing this? dirty sensors etc? apologies for ignorance !!

Sounds to me that better putting £150 towards replacement is best option.
Think it's a bit late in day for servicing.
What does complete new box cover - is converter included?

Get a scan because it will also throw up anything else that you may have missed. My ford guy pretty much said dont bother with a filter and fluid change as there is definatley more going on there that a change out will not fix. Keep the £150 for a box job my freind
£750 for the lot I beleive, of coarse could change suddenly when I go to get it done  As they suck air through teeth and so on...

I'm all for a filter and fluid change for a box that is working OK as it may prolong the life of the box for a few extra thousand miles.
Perusing a US Ford Taurus site recently and it seems it's very common to change filter and ATF every 30 K, whether this is part of Ford's Service recommendations I don't really know.

Makes sense considering the amount of work it does and the temp it gets up to, most scorps have probably never seen a change until they fail.

ok, so i have had a scan on the car at the scottish meet (thnks all), one lambda sensor and MAF (cleaned it there and then). No errors on the gearbox.
Anyone any ideas as to why it wont re-engage drive after 20mins driving?? there is a bad judder/grind from the back end when you do get it into gear when you load the power on, usually at lower gears, but also when hard accelerating midrange.
Also, anyone have a good 2nd hand g/box for a cossie? the general consensus at the meet was that it was mechanical (once the MAF was cleaned), and that a new box was going to be necessary.
thnks all

Has anybody here ever dismantled an auto gearbox? I did take a Ford C3 'Bordeaux' gearbox apart once and it wasn't that bad (though I should point out I never put it back together - I only bought it for £15 just so I could take it to bits and see how it worked).
Basically you've got the torque converter, an oil pump, a few sets of planetry gears in individual housings, brake bands and hydraulically operated clutches (wet multi-plate type like in a motorbike). On top of that you've got a couple of hydraulic servos to apply the brake bands. The hydraulic servos and clutches were controlled by the valve block (itself controlled by the gear selector lever); though on the new gearboxes the valve block would be replaced by solenoid operated valves.
Of the above, the torque converter doesn't generally cause trouble, neither do the planetry gear sets. The brake bands and clutch friction plates wear out (burning & contaminating the ATF fluid), and the solenoid valves can stick, though bad electrical connections are more likely. Insufficient hydraulic pressure due to worn out pump, leaking seals, low fluid level or blockages/restrictions will cause all sorts of problems from delays changing gears to complete loss of drive.
Why am I telling you all this? Well if you've got an original Haynes manual for the Sierra or Granada this shows a cutaway view of the C3 gearbox (and I think the A4LD) - it won't turn you into an auto box expert but if you've replaced your broken transmission and still got the old one then it might persuade you to open it up and find out what exactly went wrong with it. After all, if you understand how something works and why it's much easier to diagnose problems!

I don't know, Auto gearboxes are fairly complex units, with a combination of Electrical, Hydraulic and Mechanical technologies , even basic fluid and filter changes are probably best left to the experts.
Planetary Gears ?
Is that the reason that autoboxes don't have that typical manual box whining noise when in reverse ?

As far as I know, 2 nd gear on the Scorpio (and I assume all autos) is 2nd gear reversed which is why it's quiet and also why you could technically go over 70mph in reverse 
Correect me if I'm wrong though
