Notes: for the strain manage (laptop) solenoid: you want a minimum 4.7 ohm (or better resistance - up to ~10 ohms), 10 watt (or greater) resistor (which includes digi-key four.7cwbk-nd, $1.Sixty seven) on the strain manage solenoid wire from the trans connector pin d to the gpio board's pin 33. This resistor dissipates as much as 4 watts of strength at low line pressures (most pwm probabilities). As a end result, the resistor can get hot, so mount it on a heat sink (preferably a metal block) in a place with plenty of air movement. Together with that resistor, you may need a 1n4001 recirculation diode located among pin c and d on the 4l60e connector (the in the direction of the transmission connector the better). Be cautious to orient the diode efficaciously. These two extra external additives cut the flyback spikes from the solenoid to conceivable ranges stopping harm to various gpio board additives and probably cleaning up external alerts consisting of the vss. Any solenoid that is pulse width modulated (consisting of the shift solenoid outputs, tcc, and luf), if they are pwm'd) require which you placed a flyback diode on the solenoid. The illustrated commands are here: recirculation diode instructions. Set up an external diode between that solenoid's voltage supply and the road going to the gpio board. The banded quit of the diode is going to the voltage deliver twine, the non-banded give up of the diode goes to the road to the gpio board. Set up the diode as near the solenoid as is convenient. The 1n4001 diode is hooked up externally to keep away from bringing excessive-voltage noise into the gpio. 1n4001 diodes are to be had at really any electronics deliver keep. Without this external diode within the pwm circuits, you could harm a few internal additives. The 4 resistors for the leds can be 330 to 390 ω, ¼ watt. In case you want a 'mode selection switch' to force automobile mode or enable guide mode, you may try this with a switch and two diodes (1n4001 or equal): (this circuit handiest works with 'shift button polarity' = "energetic low".) When the mode switch is closed, vehicle mode can be used, no matter what you do with the shift buttons. If the mode transfer is open, pushing either the upshift button or downshift button will put you in manual mode (and pushing each or switching the mode choose switch to vehicle will positioned you lower back in automobile mode). Sensors: the 4l60e makes use of three kinds of sensors: temperature sensor, used to decide tcc lock-up, three stress switches (no longer that these are every now and then referred to as 'transmission pressure switches, tps, however they should no longer be careworn with the throttle role sensor), used to decide the currently selected tools (i.E., The shift lever role), automobile speed sensor (variable reluctance [vr] type), used for some of standards. Notes: there may be an early and a past due version of the 4l60e transmission. The difference is the addition of the "lockup sense" solenoids (aka. Tcc pwm solenoid). Vss (automobile pace sensor) on 2wd motors is in transmission extension housing, on 4wd vehicles the vss is in switch-case. The european also senses a brake switch and turns off the tcc solenoid every time brakes are carried out. Tcc lock-up solenoid is normally best energized in 4th equipment, if the transmission temperature is above 250°f it will energize it in 2d and 3rd as nicely. Duty cycle on the stress control solenoid is inversely proportional to the throttle perspective (as throttle angle increases, responsibility is reduced). At idle (minimum throttle), the obligation is at max (60). At wot (wide open throttle), the duty is at min (0 or off). Be aware that the pc solenoid takes the location of the throttle valve cable on in advance transmissions. Inside the tunerstudioms interface, the 0-60 sign has been converted to a forty-a hundred sign, where a hundred way maximum line stress, and 40 method minimum line stress. This *ought to* be greater intuitive for the person, hopefully. All solenoids percentage common 12v line on pin e (besides pressure manage solenoid, which has its own 12 volt deliver on pin c) and are switched on and rancid with ground.

There is no cleaning pulse (dither) each 10 seconds in this transmission (in contrast to the 4l80e). ** The tcc is pulsed (frequency is 32 hertz, with duty cycle various). Maximum present day need to now not exceed 1.Five amps. *** The 3-2 sol is pulsed at 50 hertz, 0 duty in 1st, 90 obligation in all different gears. All through a three-2 downshift, the duty is decreased and this duty is related to the car speed; lower velocity, decrease duty. # The lock-up feel (luf) solenoid changed into in all likelihood installed high end cadillacs for seamless moving. In first tools, at approximately thirteen km/h (eight mph), the oem eu pulses the luf (aka. Tcc pwm) solenoid valve at approximately 90 percentage responsibility cycle. This responsibility cycle is maintained till a tcc apply is commanded. Whilst car running conditions are suitable to apply the tcc, the oem ecu immediately decreases the duty cycle to 0 percentage, then increases it to about 25. The oem eu then ramps the duty cycle as much as about 50 to acquire regulated practice strain in automobiles prepared with the electronically managed clutch capacity (eccc). With the eccc gadget, the stress plate does no longer completely lock to the torque converter. As a substitute a regular slip of 20 to forty rpm is maintained. The fee of growth of the responsibility cycle controls the tcc follow fee. Similarly, the pcm also ramps down the luf solenoid responsibility cycle to manipulate tcc release. With some high torque or excessive automobile speeds, the converter clutch is completely locked with the aid of the oem ecu.

Fluid from various hydraulic manage circuits is fed to this the strain switch manifold which lets in the eu to decide which equipment the shift lever is presently shifted into (not always the actual equipment the transmission is in). The switch contacts are usually open and near when fluid pressure causes them to. Relying upon the circuit, the switch may also provide a floor path while closed.
