A good point on the MOSFET, we would need some of the solenoids parameters, to determine what type of MOSFETs we'd be needing, and also a MOSFET driver. Cheers hi have a valve body on the bench already what do u want to know about the solenoids ?? cheers

Well, what are some of the parameters required for determining the MOSFET needed? Current draw, voltage required for opening, and some other technical data... Basically we need the parameters of the MOSFETs that ford used in their TCM, and get something similar.
Cheers

Measure the resistance across the solenoid terminals. All of them including S5. I am very certain that they would all run on 12V. This will give us the current draw so the Mosfets can be sized.

Cheers J3 (on an EEC at least) actually allows you to completly reprogram the EEC. In other words it 'replaces' the onboard ROM chip virtually. The memory spaces of both the onboard chip adn teh J3 port overlap, with the J3 taking precedence. I've got the gear to do J3 chips. Just not the knowledge - and it's slow going.

Thats interesting... So the J3 port actually allows new data, not just manipulating the old. Well in that case, one on the TCM would be quite useful.
Do you know what ford used them for in the first place? Or was it a universal expansion capability feature? Cheers

I don't think Ford used them at all. (ie. in a stock ECU, the pins are covered with goo, so wouldn't be useable).
The ECU editing people (think Tweecer et al) have the hardware (and inportantly the software) to do live tuning/monitoring 'in car'.

As others have said, im fairly sure the 3.9's used a seperate trans controller. Would it be easier to have something that manipulated the data transmitting between the TCM and the ECU and modify the signals to get the trans to do what you wish?

easier yes, but thats not what is trying to be achieved here... you are still limited by the flexibility of the stock TCM. So while you amy be able to program the shift firmness, and perhaps shifting points, the rest is left up to the stock TCM.
Cheers

hi
will measure the resistance monday manually of all the solenoids will also source information on what the resistances are when the solenoids are new Factory limits i would also assume they run of battery voltages 12 volts checking with my electrajet software brb the J3 port i am lead to believe is a service port that ford australia has the ability to download and edit the EEC4 and EEC5 ECU have a fair bit of information and some intereting site also have EECtuner which doesnt support or little of the australian cars tweecer is similar to EECtuner seems u guys are interested also in the Engine side of things also cheers ps : andrew_ yes ur are right its easy to foul the TCM with resistors and knobs but imagine if you could control the transmission via software and it does what u want it to do also imagine all the people with earlier model falcons running on carburetors the potential to have a overdrive transmission in there car that could handle more grunt just a few input sensor signals and of u go . Im a lazy sod that's why i prefer autos had manuals in my early years and still have a few manual cars now. The BA falcon shifter i see them at swap meets heaps of them floating around all the switches are in them at ur finger tips u have a full manual valve body to control a auto actually a full electronic valve body at ur finger tips cheers

hi
sorry guys about the posting of resistances of the solenoids inside the BTR tranny have been bissy and other matters to attend will do it early this week cheers

Would the TCM for a V8 be of any assistance, I am guessing it would do the same things as the 6 TCm, but it isn't integrated into the ECU. This may be a good starting point for modification as what works on the stand alone will be easier to manipluate than digging through the ECU as well if you catch my drift

Brett YES , would be ok the V8 stand alone cheers

SOLENOID OPERATIONS -
Here day by day i will fill in a few details on the seven solenoids in the 4 speed auto BTR solenoid operations - six ( 6 ) of the seven ( 7 ) solenoids are ON/OFF solenoids with the seventh being a variable pressure solenoid ------------------------------------------------------ Solenoid - S! and S2 these are normally open solenoids these two solenoids control which gear the transmission is in Solenoid - S3 and S4 these are normally open solenoids , these two solenoids are used to control the speed and quality of the shift, they are only turned on before the shift starts and then off , with the time on varying in relation to vehicle demands and circumstances NOTE- that in some situations with no laod these solenoids will sometimes not be activiated ( eg vehicle jacked up and car driven on jac stands with no wheel loads Solenoid - S5 This solenoid operates on a duty cycle which controls S5 oil pressure which in turn has a affect on the shift quality. It operates in the same manner as a ISC operates to control the air bypass of the throttle body. Solenoid - S6 This solenoid is normally closed it is switched on ( 12 volts ) to dump pressure on the line pressure boost valve which , in turn gives low line pressure for light throttle applications.This vavle is normally off ( 0 volts ) for heavy throttle applications Solenoid - S7 This solenoid is normally closed and is switched on ( 12 Volts ) to apply the torque convertor at speeds above 80kph dependent on the throttle position.The exact speed of the when the TCC comes on is dependant also on what series ECU is installed in the car will continue with more info and technical data also SORRY ABOUT THE POOR RESULUTION ON THE PIC WILL UPDATE AS SOON AS I HAVE MY CAMERA BACK

This info is of the back of the TCU and it come out of a EA falcon 3.9lt /Btr 4 speed auto
this is what should be dismantled and reverse engineered and made programmable all the electronics is in it so how does the BTR or ford technicians program this microprocessor who's keen on deciphering the codes to the heart of ford 4 speed autos some how wire up a PC(laptop) cable and make it programmable mmmmmmmmmmm sounds easy BTR 4 speed automatic transmission controller ( Borg/Warner Australia ) BTR Eng Electronic transmission Controller BTR PART No 0585-640038 BOSCH PART No 9 260 060 033 FORD PART No 90DA-7E453-BB ( MADE IN AUSTRALIA ) THIS IS ALL THE INFO OF THE BACK OF THE UNIT WILL HAVE ALL THE PIN OUT INFO TONIGHT CHEERS

Youd need the hardware used inside, to know the physical layout of the TCM. As in what processor was used, where the memory is stored, how...etc.
Cheers
