Only 5 left in stock - order soon. 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. The best way to make sure that your shift solenoids are the root cause is to test them. Pump is the same as '95. Figure 2 shows PWM progression during typical TCC application. Please verify the year, located by the Casting Stamp near the EPC Solenoid (See the Red Arrow above). There is an early and a late model of the 4L60E transmission. FYI, since this is a solenoid, it doesnt matter which wire goes where. Max. At WOT (wide open throttle), the duty is at min (0% or off). If you need printing, shipping, shredding, or mailbox services, visit us at 13725 Metcalf Ave. 4L60E transmission solenoids
When the PCM de-energized the solenoid, the valve returned, allowing converter feed oil to switch back to the release circuit and cutting off apply pressure. It has a 12 pin case connector, extra wire in the transmission to computer harness and different computer to control the new PWM circuit. The video below does a great job of showing and explaining the step by step process for testing and replacing your 4l60e TCC solenoid. The image below shows the locations of various solenoids.

Your transmission will display a variety of symptoms, but sometimes these issues can be confused by other common 4l60e issues. OK. P0751 indicates that the transmission is shifting unexpectedly from 1 to 4 and that a likely cause is Solenoid A. ** The TCC is pulsed (frequency is 32 Hertz, with duty cycle varied). 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). Another symptom of a failed TCC solenoid is a fault code. Maximum current should not exceed 1.5 AMPS. If you apply ground or +12 to the wrong wire, you could fry the ECM (computer). 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. In addition to that, if you discover the shift solenoids are the culprit of your issues, they are inexpensive to purchase and repair yourself if you have the skills and understanding of how to do so.

The 1995 4L60E Valve Body was produced for one year only. Shift solenoid 2 should be 12-28 Ohms. At the appropriate moment, a command from the PCM to the TCC solenoid stroked the converter clutch valve, allowing release fluid to exhaust and opening the apply circuit for business. 1,031. 4l60e Shift Solenoid Guide When your 4l60e starts to act up and not shift correctly, one very likely culprit is the shift solenoids. The image below shows how easily accessible the shift solenoids are once the pan and filter are removed. If it reads a number, for example 5 ohms, then you will need to subtract 5 ohms from each reading. Under PWM control, the PCM sends a variable duty cycle to the second solenoid to control the regulated apply valve (Figure 1). If you want a 'mode selection switch' to force auto mode or enable manual mode, you can do this with a switch and two diodes (1N4001 or equivalent): There is an early and a late model of the 4L60E transmission. The TCC control solenoid was changed to a 20-31 OHM solenoid, from the previous 10-15 OHM solenoid. You often can spot TCC problems before they trigger codes by monitoring duty cycle with a scan tool. Has PWM stamped cast in pump. During a 3-2 downshift, the duty is decreased and this duty is related to the vehicle speed; lower speed, lower duty. Simple and effective. In essence, the TCC solenoid is like a computer controlled on and off switch for your 4l60es torque converter lock up. 4L60-E '96-earlier . How Much Power Will A Stock 4l60e Handle. To wire the 4L60E transmission to the GPIO board, you need to make a number of connections: (This circuit only works with 'Shift Button Polarity' = "active low".). If it is not, then simply replace it. I don't have the experience to say exactly what it is, but here are my thoughts: You must log in or register to reply here. The valves and solenoids remain (virtually) the same as with PWM operation, but the control strategy and TCC lining have again undergone changes. C: pressure control solenoid high . Grey connector, 10-15 ohms44390 may also be used.No returns on electrical components. 0000013511 00000 n
But on/off operation had some shortcomings. Switching the TCC abruptly can result in a harsh apply sensation and adds unnecessary stress to driveline components. we are a transmission one stop transmission and transmission parts store. Friction material designed for use in on/off systems will burn up when subjected to modulated slip conditions, and the lining material designed for PWM control typically wears out prematurely if used in EC3 systems. For PWM, 6 solenoid transmissions, 13 wire harness. Knowing how and why this happens is the key to avoiding converter failure comebacks which are the product of a modification someone else performed. http://shbox.com/1/electronic_trans_controls.jpg, http://www.ls2.com/boggs/a4/electroniccomponentdescription.htm, http://www.ls2.com/boggs/a4/autotransinlineharness.htm, http://www.youtube.com/watch?v=1cjli1HKPCo. TCC PWM solenoid). 5% coupon applied at checkout Save 5% with coupon. With some high torque or high vehicle speeds, the converter clutch is fully locked by the OEM ECU.

This duty cycle is maintained until a TCC apply is commanded. For these reasons the PWM control strategy was introduced. Note that the PC solenoid takes the place of the Throttle Valve cable on earlier transmissions. Typically the TCC solenoid itself costs under $30, so between that and fluid and a new filter (might as well change that while youre in there), you can be less than $100 into replacing a TCC solenoid yourself in a few hours. Within the EC3 game plan it is generally undesirable to fully lock the TCC. If you are using a later model 4L80E (apparently at the beginning of the 1994 model year) change the ' PC PWM Period ' to 1.629 milliseconds. 0000012953 00000 n

Before GM introduced its pulse width modulated (PWM) control system in the mid-1990s, the 4L60E TCC apply/release tactics were simple: on or off. When using this method youll need a 9v battery and a pair of test leads. 35382B 700R4 Torque converter clutch signal switch 1982-92. ]Z1iw'=xz U[!mxx ?b7|9 2xvSs`fQ%]kUu^eZqRc%[|yEO?fOM . 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). Similarly, the PCM also ramps down the LUF solenoid duty cycle to control TCC release. An erratic TCC lock up can be caused by an erratic input signal from the VSS (vehicle speed sensor). 3.6 3.6 out of 5 stars (20) $76.59 $ 76. This modification allows full line pressure into the apply circuit, up to 140 psi under load. Ramping this pressure in stages gives us the smooth operation and improved fuel economy were looking for.

However, when they go bad, you will notice very quickly. A common problem with PWM and EC3 units is caused by continuous oscillation of the regulator valve, which creates bore wear over time that allows critical apply pressure to exhaust. After you have attached your test leads, simply connect them to the 9v battery one at a time. These are simple plugs that have a tab that is easily released. There is a common modification for the 4L60-E TCC circuit that causes multiple problems, one of which is TCC friction delamination. 0000009637 00000 n
