Notes: for the pressure control (computer) solenoid: you want a minimal four.7 ohm (or higher resistance - up to ~10 ohms), 10 watt (or greater) resistor (inclusive of digi-key 4.7cwbk-nd, $1.Sixty seven) on the strain control solenoid wire from the trans connector pin d to the gpio board's pin 33. This resistor dissipates up to four watts of strength at low line pressures (maximum pwm probabilities). As a end result, the resistor can get hot, so mount it on a warmth sink (ideally a metallic block) in an area with lots of air stream. Together with that resistor, you'll need a 1n4001 recirculation diode placed between pin c and d at the 4l60e connector (the in the direction of the transmission connector the higher). Be careful to orient the diode efficaciously. Those two extra outside components reduce the flyback spikes from the solenoid to potential ranges preventing harm to various gpio board components and probably cleansing up outside signals along with the vss. Any solenoid that is pulse width modulated (such as the shift solenoid outputs, tcc, and luf), if they're pwm'd) require which you put a flyback diode at the solenoid. The illustrated commands are right here: recirculation diode instructions. Set up an outside diode among that solenoid's voltage supply and the line going to the gpio board. The banded quit of the diode is going to the voltage deliver cord, the non-banded quit of the diode is going to the line to the gpio board. Set up the diode as near the solenoid as is convenient. The 1n4001 diode is set up externally to avoid bringing excessive-voltage noise into the gpio. 1n4001 diodes are available at definitely any electronics supply store. Without this outside diode inside the pwm circuits, you can harm a few inner components. The four resistors for the leds may be 330 to 390 ω, ¼ watt. In case you need a 'mode selection transfer' to force automobile mode or enable guide mode, you could try this with a transfer and diodes (1n4001 or equivalent): (this circuit simplest works with 'shift button polarity' = "energetic low".) When the mode transfer is closed, auto mode may be used, no matter what you do with the shift buttons. If the mode transfer is open, pushing both the upshift button or downshift button will positioned you in guide mode (and pushing both or switching the mode select switch to automobile will placed you lower back in automobile mode). Sensors: the 4l60e uses 3 types of sensors: temperature sensor, used to determine tcc lock-up, three strain switches (no longer that these are occasionally called 'transmission strain switches, tps, however they ought to no longer be confused with the throttle role sensor), used to determine the currently selected equipment (i.E., The shift lever position), automobile velocity sensor (variable reluctance [vr] type), used for a number of standards. Notes: there's an early and a past due version of the 4l60e transmission. The distinction is the addition of the "lockup feel" solenoids (aka. Tcc pwm solenoid). Vss (automobile velocity sensor) on 2wd cars is in transmission extension housing, on four wheel drive cars the vss is in transfer-case. The european also senses a brake switch and turns off the tcc solenoid whenever brakes are implemented. Tcc lock-up solenoid is usually best energized in 4th equipment, if the transmission temperature is above 250°f it's going to energize it in 2nd and third as nicely. Obligation cycle at the strain control solenoid is inversely proportional to the throttle attitude (as throttle angle will increase, obligation is decreased). At idle (minimum throttle), the obligation is at max (60). At wot (huge open throttle), the duty is at min (0 or off). Notice that the laptop solenoid takes the location of the throttle valve cable on in advance transmissions. In the tunerstudioms interface, the 0-60 sign has been converted to a 40-100 sign, in which one hundred means maximum line stress, and 40 method minimal line strain. This *have to* be extra intuitive for the user, with any luck. All solenoids percentage not unusual 12v line on pin e (except strain control solenoid, which has its very own 12 volt deliver on pin c) and are switched on and rancid with floor.

There may be no cleaning pulse (dither) each 10 seconds on this transmission (unlike the 4l80e). ** The tcc is pulsed (frequency is 32 hertz, with responsibility cycle various). Most modern need to now not exceed 1.5 amps. *** The 3-2 sol is pulsed at 50 hertz, zero responsibility in 1st, ninety responsibility in all other gears. During a three-2 downshift, the duty is reduced and this responsibility is associated with the vehicle pace; lower pace, lower obligation. # The lock-up feel (luf) solenoid changed into in all likelihood put in excessive stop cadillacs for seamless moving. In first equipment, at approximately thirteen km/h (8 mph), the oem ecu pulses the luf (aka. Tcc pwm) solenoid valve at approximately ninety percentage responsibility cycle. This responsibility cycle is maintained until a tcc apply is commanded. Whilst car operating conditions are appropriate to use the tcc, the oem ecu straight away decreases the duty cycle to zero percent, then will increase it to approximately 25. The oem european then ramps the obligation cycle up to about 50 to reap regulated apply stress in automobiles ready with the electronically managed grab capacity (eccc). With the eccc device, the pressure plate does no longer fully lock to the torque converter. Alternatively a consistent slip of 20 to 40 rpm is maintained. The price of growth of the obligation cycle controls the tcc apply rate. Further, the pcm additionally ramps down the luf solenoid duty cycle to govern tcc release. With a few excessive torque or high automobile speeds, the converter grasp is fully locked by using the oem european.

Fluid from numerous hydraulic manage circuits is fed to this the stress transfer manifold which permits the eu to determine which gear the shift lever is presently shifted into (now not always the real gear the transmission is in). The switch contacts are typically open and close while fluid strain reasons them to. Relying upon the circuit, the switch may additionally provide a ground route when closed.
