To identify the 3-2 downshift & TCC PWM (in the above photo, '1' shows the location of the TCC PWM), solenoids are the same (low ohms). OEM White connector. Another way to test your shift solenoids is to check the ohms of resistance with a multimeter. For example, if you have a vehicle with a few clicks on the odometer and an average TCC duty cycle of 79%, you can be pretty sure the PCM is compensating for circuit wear, most likely in the regulator bore. Helps cure: TCC apply concerns; Overheated converter; Loss of lube oil; TCC Solenoid Snout Kit 77942-02K. The switch contacts are normally open and close when fluid pressure causes them to.

The procedure for replacing your 4l60e shift solenoids is as follows (if you havent started the process yet): When replacing your shift solenoids, now would be the perfect time to replace your transmission pan and filter, especially if you havent changed your fluid recently, or are wanting a transmission pan with a drain plug for future convivence. Under PWM control, the PCM sends a variable duty cycle to the second solenoid to control the regulated apply valve (Figure 1). If the TCC regulator valve bore is worn, the only way to restore the valve bore and prevent pressure loss is to install Sonnax TCC regulator and isolator valve kit 77754-04K (OE apply rate) or 77754-03K (increased apply rate). Sol A, Sol B, 1-2, 2-3 Scotties Hobbies 37.3K subscribers Subscribe 1.6K 138K views 4 years ago Buy AcDelco Shift solenoids: https://ebay.to/2EwTy1a. This is enough for extra holding power while avoiding the consequences of full line pressure to the TCC piston. 0000009213 00000 n E: ignition power feed from TCM to solenoids . The main function of the toque converter clutch or TCC solenoid is to send pressurized fluid to the torque converters clutch allowing it to achieve lock up in 4th gear based on a signal from the engine control module (ECM). The 4l60e TCC Solenoid is located on the front passenger side of the transmission near the valve body. Shift solenoid 1 should be 12-28 Ohms. If you were to pay a shop, you can expect to pay somewhere between $250 $500 depending on the labor time needed to do the job. HW TSg~Y!lMR!AYl I8@0 1nIxh6{J-[*T\Kqg*VN. Shift solenoid 2 should be 12-28 Ohms. 0000012312 00000 n * The Pressure Control solenoid controls main line pressure, pulsed at 0-60% duty cycles at 293 Hertz. You often can spot TCC problems before they trigger codes by monitoring duty cycle with a scan tool. The spring is NOT a repair for a worn regulator bore, as it is designed to work in a properly functioning apply circuit. Central Oklahoma. This is a direct replacement part, Replacement for cracked or broken lock up solenoid snout. The valves and solenoids remain (virtually) the same as with PWM operation, but the control strategy and TCC lining have again undergone changes. While the extra pressure masks bore wear and provides a Band-Aid for TCC slip, it can lead to: These problems are made worse if line pressure modifications are performed which allow even higher pressures into the apply circuit. 3.6 3.6 out of 5 stars (20) $76.59 $ 76. we are a transmission one stop transmission and transmission parts store. *** The 3-2 Sol is pulsed at 50 Hertz, 0% duty in 1st, 90% duty in all other gears. 20 to 40 ohms, splice in design, twist locks connectors included. %PDF-1.4 % 4L60E 4L65E Transmission Solenoids & Switches. FOR SALE! GM 4L60-E Shift Solenoid Quick and Easy Test. 0000008870 00000 n This adaptive control strategy can provide nuggets of diagnostic gold: as the regulator bore wears, the duty cycle required to keep slip in the appropriate range increases. ), Torque Converter Clutch Solenoid Switched GND. 0000001871 00000 n These are: The wiring inside the 4L60E transmission looks like this: The corresponding AMPseal connections for the control/sense functions are: The CAN termination resistors are already in place on the MS-II controller and GPIO board. The easiest way to identify the valve is, the second design valve will fall out as soon as the solenoid is removed. The meter should read zero or close to zero. In this video we show how to remove the transmission pan and change the shift solenoids and torque converter clutch (TCC) solenoid in Pete's 2004 Silverado 1. 0000012774 00000 n If you apply ground or +12 to the wrong wire, you could fry the ECM (computer). Measure the resistance of all solenoids. Luckily, it is pretty straight forward testing and replacing (if need be) 4l60e shift solenoids. The cost associated with replacing a 4l60e TCC solenoid is not too bad, especially if youre comfortable doing it yourself. k34326ufits 4l60e, 4l80e (9 - 14 ohms)gm solenoid, ('90-'02) 4l30e, ('93-'02) 4l60e, ('93-'03) 4l80e oem compatiable plug (3.5 - 4.66 ohms)orders are shipped out same day if ordered before 4:30pm eastern standard time! Sonnax is an industry leader in the cutting edge design, manufacture and distribution of the highest quality products to the automotive aftermarket, commercial vehicle industries, and industrial sectors utilizing drivetrain technology. Under some high-torque or freeway speed situations, the PCM will increase duty cycle to 98% to fully lock the TCC. Knowing how and why this happens is the key to avoiding converter failure comebacks which are the product of a modification someone else performed. ** The TCC is pulsed (frequency is 32 Hertz, with duty cycle varied). (Gray Connector) 1-35399A EPC solenoid No returns on INSTALLED electrical components. 35394B 4L60E Transmission 3-2 down shift solenoid 1996-ON. Please verify the year, located by the Casting Stamp near the EPC Solenoid (See the Red Arrow above). No other repairs were made and the transmission was not removed from the car. A second TCC solenoid was added to control the regulated apply valve. With this information in mind, it becomes apparent how a torque converter that was built perfectly to specification can fail due to being installed in an improperly modified transmission. The pressure switch manifold (PSM) is a multiple switch assembly consisting of 3 normally open (NO) pressure switches and 2 normally closed (N/C) pressure switches. Depending upon the circuit, the switch may provide a ground path when closed. With anti-drainback valve. For 1996 and up, the 3/2 downshift solenoid should be 12-28 Ohms. rockbuggy84 said: 20 to 40 ohms, splice in design, twist locks connectors included. 0000008666 00000 n A friction lining with higher thermal capacity must be used such as the HTS (High Thermal Slipping) linings offered by Sonnax. Note that the PC solenoid takes the place of the Throttle Valve cable on earlier transmissions. What Is Convertor Lock Up In A 4l60e Transmission? 0000013697 00000 n The TCC control solenoid was changed to a 20-31 OHM solenoid, from the previous 10-15 OHM solenoid. I am interested in enhancing my vehicles performance. When your 4l60e starts to act up and not shift correctly, one very likely culprit is the shift solenoids. If it is not, then simply replace it. Like it or not, modifications will always be a part of this business. At WOT (wide open throttle), the duty is at min (0% or off). The image below shows the locations of various solenoids.
