Wiring diagram for a 4l60e transmission - Notes: for the strain manage (computer) solenoid: you need a minimum 4.7 ohm (or better resistance - up to ~10 ohms), 10 watt (or more) resistor (such as digi-key four.7cwbk-nd, $1.Sixty seven) at the stress manipulate solenoid cord from the trans connector pin d to the gpio board's pin 33. This resistor dissipates up to four watts of energy at low line pressures (most pwm probabilities). As a end result, the resistor can get warm, so mount it on a warmth sink (preferably a metal block) in a place with lots of air circulate. At the side of that resistor, you may want a 1n4001 recirculation diode placed among pin c and d at the 4l60e connector (the toward the transmission connector the better). Be cautious to orient the diode successfully. These additional outside components reduce the flyback spikes from the solenoid to attainable degrees stopping damage to diverse gpio board additives and probably cleansing up outside indicators consisting of the vss. Any solenoid that is pulse width modulated (which includes the shift solenoid outputs, tcc, and luf), if they're pwm'd) require that you placed a flyback diode on the solenoid. The illustrated instructions are right here: recirculation diode commands. Installation an external diode among that solenoid's voltage supply and the road going to the gpio board. The banded end of the diode is going to the voltage supply cord, the non-banded quit of the diode goes to the line to the gpio board. Set up the diode as near the solenoid as is convenient. The 1n4001 diode is hooked up externally to avoid bringing high-voltage noise into the gpio. 1n4001 diodes are to be had at honestly any electronics deliver shop. With out this outside diode within the pwm circuits, you can harm a few internal additives. The four resistors for the leds can be 330 to 390 ω, ¼ watt. In case you need a 'mode choice switch' to pressure vehicle mode or allow manual mode, you can do this with a switch and two diodes (1n4001 or equal): (this circuit most effective works with 'shift button polarity' = "energetic low".) When the mode switch is closed, vehicle 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 placed you in guide mode (and pushing each or switching the mode select switch to car will positioned you again in car mode). Sensors: the 4l60e makes use of three sorts of sensors: temperature sensor, used to decide tcc lock-up, three stress switches (not that these are from time to time known as 'transmission stress switches, tps, however they ought to no longer be stressed with the throttle position sensor), used to determine the currently decided on tools (i.E., The shift lever role), automobile pace sensor (variable reluctance [vr] type), used for a number of standards. Notes: there's an early and a late model of the 4l60e transmission. The difference is the addition of the "lockup experience" solenoids (aka. Tcc pwm solenoid). Vss (car pace sensor) on 2wd vehicles is in transmission extension housing, on 4wd vehicles the vss is in switch-case. The european additionally senses a brake switch and turns off the tcc solenoid each time brakes are implemented. Tcc lock-up solenoid is generally best energized in 4th tools, if the transmission temperature is above 250°f it'll energize it in second and 3rd as properly. Responsibility cycle at the stress control solenoid is inversely proportional to the throttle attitude (as throttle angle will increase, responsibility is decreased). At idle (minimal throttle), the obligation 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 location of the throttle valve cable on earlier transmissions. In the tunerstudioms interface, the 0-60 sign has been transformed to a forty-100 sign, in which a hundred manner most line strain, and forty manner minimal line stress. This *must* be extra intuitive for the user, with any luck. All solenoids share not unusual 12v line on pin e (besides pressure manipulate solenoid, which has its own 12 volt deliver on pin c) and are switched on and off with floor.

There is no cleansing pulse (dither) every 10 seconds on this transmission (not like the 4l80e). ** The tcc is pulsed (frequency is 32 hertz, with responsibility cycle varied). Most modern ought to no longer exceed 1.5 amps. *** The three-2 sol is pulsed at 50 hertz, zero obligation in 1st, ninety responsibility in all different gears. During a three-2 downshift, the duty is reduced and this responsibility is associated with the car velocity; lower velocity, decrease obligation. # The lock-up sense (luf) solenoid turned into probably put in excessive give up cadillacs for seamless moving. In first gear, at approximately 13 km/h (8 mph), the oem eu pulses the luf (aka. Tcc pwm) solenoid valve at about 90 percent duty cycle. This duty cycle is maintained till a tcc follow is commanded. While car operating situations are suitable to apply the tcc, the oem eu right away decreases the obligation cycle to 0 percent, then will increase it to approximately 25. The oem european then ramps the responsibility cycle up to approximately 50 to gain regulated follow stress in motors geared up with the electronically controlled clutch capability (eccc). With the eccc machine, 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 rate of growth of the duty cycle controls the tcc observe price. Further, the pcm additionally ramps down the luf solenoid responsibility cycle to manipulate tcc release. With some excessive torque or excessive vehicle speeds, the converter grab is absolutely locked by the oem eu.

Fluid from diverse hydraulic manipulate circuits is fed to this the strain transfer manifold which lets in the european to determine which equipment the shift lever is currently shifted into (no longer necessarily the actual tools the transmission is in). The switch contacts are typically open and near whilst fluid strain reasons them to. Relying upon the circuit, the switch can also offer a floor route when closed.
