Notes: for the pressure control (laptop) solenoid: you need a minimal 4.7 ohm (or higher resistance - as much as ~10 ohms), 10 watt (or extra) resistor (which includes digi-key four.7cwbk-nd, $1.67) at the strain manipulate solenoid twine from the trans connector pin d to the gpio board's pin 33. This resistor dissipates as much as four watts of electricity at low line pressures (most pwm probabilities). As a result, the resistor can get warm, so mount it on a heat sink (ideally a metallic block) in an area with lots of air flow. In conjunction with that resistor, you'll want a 1n4001 recirculation diode positioned between pin c and d on the 4l60e connector (the towards the transmission connector the better). Be cautious to orient the diode efficaciously. Those extra external additives cut the flyback spikes from the solenoid to potential degrees stopping harm to numerous gpio board additives and potentially cleaning up external indicators together with the vss. Any solenoid that is pulse width modulated (which includes the shift solenoid outputs, tcc, and luf), if they are pwm'd) require that you placed a flyback diode on the solenoid. The illustrated instructions are right here: recirculation diode commands. Installation an outside diode among that solenoid's voltage deliver and the line going to the gpio board. The banded cease of the diode goes to the voltage supply cord, the non-banded end of the diode goes to the line to the gpio board. Set up the diode as close to the solenoid as is handy. 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 surely any electronics deliver save. With out this external diode within the pwm circuits, you could harm a few inner additives. The 4 resistors for the leds can be 330 to 390 ω, ¼ watt. In case you need a 'mode choice transfer' to pressure automobile mode or permit manual mode, you may do this with a transfer and two diodes (1n4001 or equivalent): (this circuit simplest works with 'shift button polarity' = "lively low".) Whilst the mode switch is closed, vehicle mode can be used, no matter what you do with the shift buttons. If the mode switch is open, pushing either the upshift button or downshift button will positioned you in manual mode (and pushing both or switching the mode pick out switch to auto will placed you back in car mode). Sensors: the 4l60e makes use of 3 sorts of sensors: temperature sensor, used to determine tcc lock-up, three pressure switches (not that those are sometimes called 'transmission pressure switches, tps, however they need to now not be stressed with the throttle function sensor), used to determine the currently decided on equipment (i.E., The shift lever position), vehicle pace sensor (variable reluctance [vr] kind), used for a number of criteria. Notes: there may be an early and a late version of the 4l60e transmission. The distinction is the addition of the "lockup sense" solenoids (aka. Tcc pwm solenoid). Vss (vehicle velocity sensor) on 2wd automobiles is in transmission extension housing, on four wheel drive vehicles the vss is in transfer-case. The ecu also senses a brake transfer and turns off the tcc solenoid whenever brakes are implemented. Tcc lock-up solenoid is normally handiest energized in 4th gear, if the transmission temperature is above 250°f it'll energize it in 2d and 3rd as nicely. Duty cycle on the pressure control solenoid is inversely proportional to the throttle attitude (as throttle attitude increases, responsibility is decreased). At idle (minimum throttle), the duty is at max (60). At wot (wide open throttle), the responsibility is at min (zero or off). Be aware that the computer solenoid takes the region of the throttle valve cable on earlier transmissions. Inside the tunerstudioms interface, the 0-60 sign has been transformed to a 40-100 sign, wherein one hundred manner most line stress, and forty approach minimum line pressure. This *need to* be more intuitive for the user, optimistically. All solenoids share commonplace 12v line on pin e (except stress manipulate solenoid, which has its own 12 volt deliver on pin c) and are switched on and stale with ground.

There may be no cleaning pulse (dither) each 10 seconds in this transmission (unlike the 4l80e). ** The tcc is pulsed (frequency is 32 hertz, with responsibility cycle varied). Most contemporary ought to not exceed 1.5 amps. *** The three-2 sol is pulsed at 50 hertz, zero obligation in 1st, ninety duty in all different gears. For the duration of a 3-2 downshift, the duty is decreased and this duty is related to the automobile speed; lower pace, lower responsibility. # The lock-up feel (luf) solenoid became probably installed high stop cadillacs for seamless transferring. In first equipment, at about 13 km/h (eight mph), the oem ecu pulses the luf (aka. Tcc pwm) solenoid valve at approximately 90 percentage responsibility cycle. This duty cycle is maintained until a tcc apply is commanded. When vehicle operating situations are appropriate to use the tcc, the oem eu straight away decreases the duty cycle to zero percent, then will increase it to about 25. The oem european then ramps the duty cycle up to about 50 to attain regulated observe pressure in motors prepared with the electronically managed take hold of ability (eccc). With the eccc gadget, the stress plate does no longer completely lock to the torque converter. Rather a constant slip of 20 to 40 rpm is maintained. The fee of boom of the obligation cycle controls the tcc practice fee. In addition, the pcm also ramps down the luf solenoid responsibility cycle to govern tcc launch. With some excessive torque or high vehicle speeds, the converter snatch is fully locked by the oem eu.

Fluid from various hydraulic manipulate circuits is fed to this the stress transfer manifold which allows the eu to determine which gear the shift lever is presently shifted into (no longer necessarily the real gear the transmission is in). The switch contacts are generally open and close when fluid stress reasons them to. Relying upon the circuit, the transfer may offer a floor course when closed.
