Fixed! was a solenoid. local trans workshop diagnosed it from my description did not look at the car I asked how to identify the B solenoid which in the trans are marked S1 S2 S3 S4 said you need a book (I could not find that information anywhere) and would not elaborate further so I booked the car in.

Well that did not work! P0758 (solenoid B) the solenoids in the transmission are marked S1 S2 S3 does anyone know which one is solenoid B as indicated by the scan tool fault code P0758

I serviced it when this first happened made no difference. Have unplugged the transmission connectors and the PCM connectors. sprayed them with electrical cleaner and worked them on and off several times so far so good.

just done another scan with Forscan this time it picked up a code P0758 now I can address the problem. thanks to those who replied.

Puffwagon thanks for your thoughts. Just spoke to the local ford dealer service department could not tell me where I could source a list of the dash codes including the one I was seeing. I would have to bring the vehicle in and have it scanned the cost $200 (5 minute scan) and I thought my heart specialist knew how to charge! Rang ford Australia which took my vin number and tried to assist however advised they were not technical enough and I should try another dealer. Well, off to the local transmission specialists to see if they can help.

k31th. thanks for the reply, I have checked for fault codes with HP Tuners and Forscan and there are no fault codes logged. It is annoying that the car is identifying a transmission (BTR) fault but nothing is being logged happened several times today.

2008 G6 LPG falcon I have a transmission fault come up on the dash screen (no fault logged with scanner) yellow triangle with exclamation mark says press "SEL" when I press SEL it comes up with a white triangle with an exclamation mark with the numeral 1 beside it. Does anyone know what this means or where I can find the information? Thanks John

Ok Thanks!

Thanks for that list of pids , I have configured the histogram in various configurations and will still only show counts, hopefully with this list of pids it will now work. Can anyone tell me what the significance/difference of upper and lower case pids are? Can anyone tell me which option should be used and under what circumstances the other two option would be used? Use previous list of pids if available (validate all other pids otherwise) Validate all pids in list do not validate pids Thanks!

I used some lowercase and some uppercase, I read somewhere uppercase should be used, what is the significance? It is difficult to determine which is the correct pid to use. The ones I want to log are: LOAD_FROM_MAP (several to choose from not sure what the difference is) SPKADD_AVG_ALL (knock retard seems to work ok) RPM (seems to work ok) INJECTOR PULSE WIDTH (Appears not to have a pid for this) On the chart screen they display fine on the histogram it will only show the count

Buggered if I know what I am doing wrong tried that way! will have to go over the steps again, there is not a lot to set up and appears very little to go wrong but I can only fill the histogram with counts nothing else works, anyway thanks for the reponse.

Has anyone used the new Livelink Gen-11 scanner software and if so have you had any success geting the histogram to work?. I have tried and can only get the counts to work on an FGXR6T!

I guess the question I ask myself how do you determine if an engine is knocking and which is more accurate for determining this, the manufactures knock sensing hardware/software or an aftermarket one or the human ear with a listening device. My money is on the manufactures hardware/software which is calibrated for the specific engine type. It looks for knock in a narrow window of time in relation to the ignition cycle, it is looking for a specific frequency based on cylinder size and then filters all unwanted frequencies, it is looking for the intensity of signal generated by the knock sensor and depending on intensity of the signal from the knock sensor the level of knock is determined. This is then compared to preset parameters in the tune program from development work done by engineers for that specific engine, below these preset parameters it is considered not to be knocking above the preset parameters it is considered to be knocking. While aftermarket knock sensing is definitely better than nothing (noting VCM suite does not report knock) I believe that no aftermarket knock detection system can match the manufacturers knock detection sophistication.

Ratter I acknowledge the positive contribution you have made to this forum over a long period, and I can see how I would be viewed as a "Johnny come lately" however I feel as strongly about road/track tuning from experience as you obviously do about dyno tuning and as you said "Every one is welcome to believe what they want"

"Yortts post is again a classic example of cut and paste" This is what I have experience from comparing dyno tuning and tuning at the track, my experience is from Holdens and turbo 4cylinders. I made it quiet clear that the article was lifted from the net and I did so as it was written by a very experienced reputable motoring journalist not a hack journalist as suggested. The information is now everywhere on the net, those that want to be enlightened search read evaluate weigh up the varying opinions and conclude for yourself. I am not asking anyone to agree with me or dictate my opinion to any one just offering an alternate view based on my experience. "A smart dyno operator will run the dyno at a ramp rate that close to matches the acceleration rate of the car in the gear being tested" All I can suggest to others reading this post is next time you have your car run up on the dyno note the number of seconds it takes to do the run then go to the track and do the same test in the same gear and compare the time in seconds again, this will answer the question. "Your point about MBT is wrong, different configuration motors will drop power sometimes before knock has been reached while others will make more power while pinging, guess which one the Ford turbo is, yes the one that making power while pinging with 98 octane fuel, so your drag mph could end up with a motor that is grenaded by tuning it that way, but what about part throttle mbt etc how are you going to do that? On 98 octane fuel and below I do not accept your premise and no one is suggesting you drive the tune past the knock threashold. Any thing above 98 octane fuel I would agree with you as you the have the ability to light it up too early BTDC in the compession stroke and achieve maximum cylinder pressures too early ATDC and loose power. "The ford calibrated knock sensor is far from accurate and will pull spark when there is no knock, we have proved this time after time with electronic knock detection and it also picks up knock events before the human ear will." I know the sophistfication of the Expensive Daewoo knock system and logic would dictate that Ford would be very similar and would have spent millions of dollars developing knock detection in particular for forced induction, no aftermarket system would have access to the expertise or budget ford would have. Your comment "The ford calibrated knock sensor is far from accurate and will pull spark when there is no knock" given my above comments I can not see how any independent workshop could have access to equipment to determine this. No aftermarket knock sensing has the ability to listen through the correct window in the combustion cycle filtering all unwanted noise and listening to the specific knock frequency generated by that particular engine and accurately determine the intensity level I know Expensive Daewoo do and I see no reason why Ford would not. .
