When vehicle operating conditions are appropriate to apply the TCC, the OEM ECU immediately decreases the duty cycle to 0 percent, then increases it to approximately 25%. Has PWM stamped cast in pump. 35386A 4L60E 4L80E Transmission (MLP) manual lever position switch 1995-2003. The easiest way to identify the valve is, the second design valve will fall out as soon as the solenoid is removed. They both showed significant wear using a wet-air-test technique. The best way to make sure that your shift solenoids are the root cause is to test them. ]Z1iw'=xz U[!mxx ?b7|9 2xvSs`fQ%]kUu^eZqRc%[|yEO?fOM 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. 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.

There is at least one aftermarket kit that mimics blocking the valve, with the same detrimental high pressures being allowed to the apply circuit. 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. (913) 851-7711. As a further effort to improve fuel economy and prolong the life of transmission and engine components, PWM control evolved into EC3. 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). This is enough for extra holding power while avoiding the consequences of full line pressure to the TCC piston. (Gray Connector) 1-35399A EPC solenoid No returns on INSTALLED electrical components.

As the TCC solenoid is the only one physically attached to the wiring harness, i though one might me able to test across the TCC pin and 12+input, and check the resistance there (click image). 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. Instead, a consistent slip of about 20 to 40 RPM is aimed for under most operating conditions. I work on other peoples vehicles for a living. OEM White connector. CPT 4l60e participates in the Amazon Associates program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com, as well as other participating programs to help fund and maintain the website. Estimate Shipping Cost. Since the apply pressures are capped in this manner, the pressure limiter can be used with friction linings designed for on/off, PWM or EC3 with great success. None of the above categories describe me. I tried it and got 24 ohms at 20degrees C. Does that sound correct? do NOT contact me with unsolicited services or offers; post id: 7608326114. posted: 2023-04-08 14:51. HTE (High Thermal Engaging) friction linings available from Sonnax are a good example of this type. The switch contacts are normally open and close when fluid pressure causes them to. 4L60E 4L65E Transmission Solenoids & Switches. Transmission builders quickly realized they could eliminate these codes (but not the bore wear that caused them) by blocking the regulator valve with an inner pump slide spring from a 700-R4, effectively returning it to an on/off system (Figure 3). ^yM|m4/>#'$&y0. 20 to 40 ohms, splice in design, twist locks connectors included. Borg Warner aftermarket in black connector, Internal sensor-bolts to the back of the pump housing. . 0000002609 00000 n

However, a 90 elbow, or maybe even some tubing, will be required in most installs to keep the sensor away from the transmission tunnel. # The Lock-Up Feel (LUF) solenoid was probably put in high end Cadillacs for seamless shifting. If the solenoid works, youll hear a clicking sound when you go to attach the 2nd wire to the battery. There are 2 shift solenoids in a 4l60e (1-2 and 2-3), and both control up and downshifts with fluid passing through them when commanded to do so by the computer. 137th & Metcalf. I am interested in enhancing my vehicles performance. The valve opens allowing for fluid to apply the TCC, and when the signal stops, the fluid is then vented out which will then disengage the clutch. TGM-HR GM Harness Connector Removal Tool for 4L30E, 4L60E, 4L80E, 4T40E. K77929U 2004R 700R4 4L60E TCC sol (use 35391A) Lockup Solenoid for GM 700R4 4L60E & 2004R. 1,031. Next, take your test leads and connect them to the backside of the solenoid where the electrical prongs are. Any solenoid that is pulse width modulated (including the shift solenoid outputs, TCC, and LUF), if they are PWM'd) require that you put a flyback diode on the solenoid. 10 0 obj

With the isolator valve removed and the PWM feed orifice in the separator plate blocked, installing the limiter behind the regulator valve regulates line pressure into the apply circuit down to a maximum of 100 psi (Figure 4). While 4l60e shift solenoids do go bad, its not a common occurrence. T: tcc solenoid (on/off in pump) U: tcc pwm solenoid (valve body) 0000009817 00000 n
Remember that the solenoids fail under LOAD! The OEM ECU then ramps the duty cycle up to approximately 50% to achieve regulated apply pressure in vehicles equipped with the Electronically Controlled Clutch Capacity (ECCC). 3.6 3.6 out of 5 stars (20) $76.59 $ 76. Making changes to increase performance, to prevent known issues from cropping up or to overcome existing problems is a hallmark of the ingenuity of the rebuilding industry.
