first of all,i think this is fatal!!!!my 97' 2.9 24v recently suffered from "cattle grid syndrome"however today whilst on the m1 i noticed she was very reluctant to change up to 4th from 3rd gear under acceleration  if i backed off the throttle she changed up to 4th i know this because by depressing the o/d button you can feel the gear change however i have to say i no longer notice the "cattle grid "effect.....anyone any ideas because i think it may be time to admit defeat

Hi Gaz,
Firstly you should try this;
http://www.fordscorpio.co.uk/cleanmaf.htm
If it makes no change then get you car pluged in for some OBD.
You got a flashing O/D light?

maf is clean as a whistle the o/d light used to flash when encountering cattle grid syndrome,however no flashing and no cattle grid??the gearbox works very smoothly and does select 4th when backing off or drifting along,strange,but under hard acceleration in either "s" or "e" well it revs for england,is this normal?will it stay in 3rd until red line?gear oil is level but a little off red colour,smells but doesn't all oil have a smell,i think the car auction is beckoning...be carefull all,thanks,,,gaz

Gaz,
Don't panic yet. It may be that the 3-4 shift solenoid is sticking slightly. If the gearbox fluid isn't burnt and foul-smelling and the autobox takes up the drive without too much delay it might be that just one solenoid needs replacing.
Did you ever get the OBD read? After the O/D light flashes there must be a DTC stored by the PCM and it stays there until three consecutive journeys without the same problem clears the code.
Meet with an OBD-equipped owner and have a look at the DTCs - this may well tell you all you need to know.

the box takes up drive within a second or so in "r" or "d" or from one to the other,if the solenoid is dodgy do you think this why i have lost the cattle grid effect from 3rd to 4thwhere can i get the fault codes read

Eric_R, I have similar problems to Gaz (see overdrive not engaging). I do not have the cattle-grid. I do have an OBD. Would the sticking solenoid give dtc's. What readings on an OBD scan would be needed to identify the area of the problem.

Hi Jim,
A sticking solenoid SHOULD produce a dtc.
What software do you use with your OBD lead? Vehicle Explorer?
If so, You only need to check for logged dtc's on the codes page!!

Jim and Gaz,
If you have an OBD lead you can read any DTCs from the OBD system in VE by logging in to the system and selecting CODES page and request the codes.
Then, still on the CODES page, select ENHANCED and send for any Ford-specific codes.
If you have a solenoid malfunction expect a DTC in the range P1730-33 or P1761, which has been seen before.
See http://www.fordscorpio.co.uk/easyguide.htm for the simple guide, and http://www.fordscorpio.co.uk/ccmonitor.htm
BTW, a Cattle-grid syndrome does not necessarily mean that there is a problem with the autobox. I noticed cattle-grid on my Scorpio in 1998, but to date I have not found a single DTC on my car and the autobox works flawlessly - I just drive to avoid the noise - see http://www.fordscorpio.co.uk/cattle.htm

GAz,
I'm sorry to hear that, m8 but a sticking solenoid is unlikely to be repaired by changing the fluid and filter - this is only useful on high-mileage gearboxes that are behaving well.
Ask again for anyone in the Sheffield area to meet you with an OBD lead and do an Enhanced check on your codes. I'm sure that will produce the answer you need, but again if you go to a skilled techy with experience in Ford autoboxes he will probably be able to tell which solenoid to check from experience alone. You need to ring around for a good specialist in your area.
BTW, how was the autbox fluid before he changed it? Was it still a good red colour, or burnt and smelly? If the latter then it would probably be best in the long run to go for a recon box.

hi again,just a short update,i took my car back today to the box specialist and told him to go on the m1 and find 4th gear,guess what 1 hour later my phone rang,he said "yes mr carr i see what you are saying" phew at last! he talked about "lock up" aswell ? not sure what all this is about,surely if the fault is 4th gear(o/d) then this is where he should be looking?? i have told him to bitz the box(gulp) and report back,he says worst scenario is recon the box for £800.00,best scenario £?,he says the oil was a little discoloured and found a little gritty stuff in the box sump but nothing to show any broken parts,he has taken it to another garage and checked for any fault codes but it read clear,well i should know by tuesday 15/2 so keep your eyes peeled on this thread,does anyone know what happens when the gearbox wiring deteriorateswould this be apparent when he removes the boxthanks all for advice,,gaz

UPDATE**UPDATE***
the gearbox specialist rang today and said one of the bands was burnt out and that there was virtually nothing left on it??he has checked all the electronics and they are all ok,he reckons it will amount to about £300.00,,is this a fair price removal,repair,refit

gaz ... in my opinion it's too reasonable !! ..it would be absolutely daft to replace one band when it's virtually the same job ... <gearbox removal and refit .. box strip etc >... and £300 is a bit too cheap for a full recon .. i'm a tiny bit suspect mate ... see what I mean I hope ?? ..see what everyone else thinks ....regards...

hi fellas,sorry i may have misled you,he is only replacing the worn band,what is the band?what does it do?he says all the solenoids were ok and not sticking,he mentioned that the servo was worn?he says that as well as the new parts in the box he is replacing all the gaskets and new oil,but depending on the parts prices it will finish up at around £300 - £350,what are you saying then?is it not likely that the worn bands will cause my fault?left me very confused

Hi there gaz , have read of this article http://auto.howstuffworks.com/automatic-transmission.htm
It might help explain in simplistic terms what the different parts of the Auto box do, and how they work.....
