Code not specific enough to be of help. Suprises me that the 2.2 power putput causes the auto box problems, and always wonder if there are any engine codes as well, because a faulty crank sensor is known to upset the autobox with that engine.... Or if the automatic transmission fluid was ever changed during the cars life...?

Suspect the ecu has detected slipping or loss of drive. If the fluid is at the correct level with engine running there is little to be done to repair it other than relpace with a known good one.

no sure if oil was ever change: I bought this vehicle almost 2 yrs ago. and the probs has been there since, and the funny part of it is that at times it will drive normally and 4 me to find a quick solution, several times whenever it cud go in this condition and I stop and turn the engine off for few seconds, then restart the engine the car would drive normal, and up to now its like that. thax 4 ur effort sir.

So far we have an engine ECU code that indicates a request from the gearbox controller to go into limp-home. This indicates that the gearbox ECU has raised an error so the next step is to check the gearbox ECU codes, as I'm sure these will be more specific and may, for example, point to an electrical issue in the wiring to the gearbox.

Meanwhile, a check / change of the auto gearbox fluid would do no harm.

In addition, go through all positions of the auto gearbox selector and make sure that the corresponding lights on the centre console light up cleanly and without flickering between positions. A common problem is that the selector switch gets dodgy and then the auto gearbox ECU gets confused and goes into limp home.

Im thinking - plug in reader,see what it says.depending on info - check ATF level/condition,check electrical connections to gearbox.
Possibility of cam sensor or MAF problems upsetting gearbox ?

Paid a flying visit to the OP today.Time was short,light was starting to fade and it was cold,but read the codes from engine and box and removed the powersounder as it was doing me ead in.Smashed it up inTescos car park and chucked it in their bin.

Engine codes which came up were as follows -
PO700- EOBD - stored by Transmission control module.
P0136 - o2 sensor high voltage. Not present.
p0170- lean exhaust - present.
p0141 - o2 sensor heater open circuit - present.
P0340 - cam circuit no signal - not present.
p1700 - SVS request via CAN - not present.
p1405 - feedback sensor EGR - not present.
p0036 - o2 sensor heater circuit range/performance bank1 sensor 2.present.
p0304 - cyl4 misfire detected - not present.

Cleared codes, then read them again and had -
p0700 present
p0141 - present
p0304 - present
p1700 - present.

Then read gearbox codes -
p0727 - can recieves error - not present
p1781 unknown DTC - not present
p1740 - unknown DTC - present.

Ran out of time and light at this point.


HELP!!!!!!!!!!  ;D

Guessing a new Lamda sensor may clear some of these codes,but doubt its related to the problem as originally posted. :-\

Although it`s showing as not present, cam sensor will throw that code

Not a problem Gibby.Happy to try to help.Thats what the forum is for. :y
The part which you mentioned you had purchased sounds like a cam sensor to me. Might be worth changing that to see what improvement it makes.As you know I was short of time today (between night shifts and wifey - whom isnt very well at the moment - was in tescos shopping) but I will try to make some time as soon as possible to spend some more time trying to help get it sorted.
Hopefully that will be within the next week. :y

Meanwhile - any more suggestions from thos who are more knowledgeable than me are more than welcome.

Hard to tell why it would suddenly stop and refuse to restart. :-\ Hopefully some others will be able to offer opinions on possible causes. I will come back and have a look/ read the codes again/help if possible as soon as I possibly can. At the moment,the first possible day would be Wednesday.although that is dependant on Christmas shopping plans etc. - havent started yet. :y

p1740 - i think that relates to the torque convertor or the control of it for lockup if that helps....
i didnt bother reading the previous posts again but was the fluid changed and the correct level?
i've emptied some fluid out of my autobox the other day and when properly hot and run in all gears properly (4th in perticular) i sometimes get a "check - low fluid level" on the mid so im topping up or completly changing the gearbox fluid this next week to see if it stops it going into limp mode - it now only happens when cold and either it kicks down or when you load it up too much like hard acceleration
