Hi beer turbo, i have lowered the temps, but i wanted to know at what vehicle speed they turned off. my testing shows the pull through rate of air through the stock radiator is about 7m/s. I assume the car travelling at 25km would push the same air through if the fans were stopped. Fans become a restrictor at higher vehicle speed and i dont know what setting that is in the ecu. Adjusting the temps can achieve the end result as vehicle motion helps cool, and hence the fans turn anyway. I would still like to know what the setting is though.

Has anyone tested at what speed the fans get told to turn off: auF0380 looks like a start for fans at load, which is tied in with auF0379 load trigger i presume. Seem like this is not used as we rarely get above 160kmh auF2199 min speed to turn off fans - could be this one? auF1424 speed below which base fan speed is required - is that slow fans if the temperature has not reached high speed enable auF0377. I may have run some wires and LED's onto the relays and play with the speed numbers to work this out.

That would be a great tip. Ive tried various settings, but it looks like the output only comes on during rpm.

Tried setting downshifts in table 27 to 0, no luck can only get 1 and 2 without speed. There must be something in the code that is stopping a change to 3 onwards. Will keep looking for it.

Anyone have experience with getting the zf into 3,4,5,6 at standstill in manual mode. For the purposes of testing. Table 27? Downshift columns to be made say 0? Will try it. Let u all know.

PROBLEM RESOLVED: Thanks Bill and Roland. Reverse relay faulty. I was getting 100ohms then open circuit on pins 7-15 REVERSE Relay dangling under the ecu. If the relay is coil is not there (faulty) the display will flash PRND123456, not in limp mode everything works, just the IC flashes the position. With a working reverse relay the TCM sees the 100Ohm coil its all happy. Everything now working, displays all gears on reds as well. The other good news is that TCM works with LD, MC, MD strategy codes. Always check your wiring...

Hi Bill, thanks for the assistance. Loaded MC in, on reds no display. On start up flashed P in park. I've pulled my TCM off my faulty valve body and attached it to the cable i.e. let it sit there with the solenoid out in the open and attached to the PCM. The original tune file in the TCM is MD, has always worked on this valve body so I am not sure why it should be MC. Anyway I cant get it to show any PRND indicators by moving the sensor on the TCM.

Well that is interesting. Ive used my file from 3 years ago and it was MD. Extra information: when I put the new gearbox in and plugged it in, on Reds I could see P,R,N,L,D displaying correctly, this is when I decided to fill it with Oil as the instrument cluster and PCMTEC upload was all working. Afetr starting the car the PRNDL IC started flashing, but it wasnt in limp mode. I'm also now seeing with FORD IDS reverse circuit open. Will check that out, as the wiring diagram shows both side of the reverse relay coil being controlled by the TCM.

No Luck, still the same. I have flashed in my OEM TCM File (albeit the serial number could not be loaded and pcmtec merged me a new file). The TCM in the new gearbox was 5R29-7J105-LD. The original TCM 5R29-7J105-MD has now bee loaded. Instrument Cluster is not displaying shifter position on reds. When Engine ON and Running blinking "P" HADCHN4 TCM_serial_merged_from_6FPAAAJGSW7K64313.tec Ive move the linkage position at the lever to no avail. Posting my tune file in full to see if anyone has any ideas?

Hi Roland. Strategy number remain unchanged. I hesitated loading my original tcm coded "md" ( last two digits) into the working gearbox currently sitting with "LD". My pcm and tcm were originally Desired tranmssion calibration =2 For MD. You also have this in your pcmtec database. I will load my oem tcm file into the tcm and advise.

Thank you. I will read the current tcm (newly installed LD) and store it aside. I will then flash my original tcm (MD) into it. I will let you know the outcome.

The dash is flashing p,r,n,d,1,2,3,4,5 when in any of the gears. I am NOT in limp mode. The gearbox is changing gears ok, up and down. In performance mode perfect. Only the dash is flashing the gear selected. Dtc is throwing up B2681 (ic) PRNDL sender failure. Car wont start in R and D so it knows the lever and gearbox is in good position. Now whats led to this a new gearbox with valve body. BF2 to BF2. The tcm ive put in 2 months newer than the original strategy 5r29-7j105-LD. The new tcm is 5r29-7j105-MD. I have mateched the numbers in AUF1692 and ZF03987. As mentioned. Car runs, like there is no problem at all. But can seem to stop the dash flashing. Normally on reds, i should see which gear i am in, but cant see it, only when the car is running, very strange. Any ideas?

Update to the above, I have installed the twin throttle data for the GT500 and works great! very smooth. Idling at smooth 600rpm and excellent response.

cool... many thanks. Will now work on high slope and try to find breakpoint

Dolan, Engaging 4th gear uses the E-Drum - its calle the dredded e-drum for a reason. For the oil to pressurise the e-drum it passes through the centre of the pump stator. There are teflon seals that keep the oil pressurising the E-Drum. On the other side there is a bush that stops the oil passing. So you rely on seal ring and a bush to maintain good pressure on the e-drum. Most people keep increasing the pressures in the tune to compensate, but alas its a bandaid if the bush is worn or seal rings are not working properly. Then you have clutch wear to deal with. Then there is the valve body itsekf and internal accumulators. I replace all bushes, install new accumulators and vac check the valve body. Use Penrite LV or Lifeguard - ive had good success with either. change the LV regularly. Hope this helps?
