F]:(6I5j4 Fits '97-later PWM units. This control scheme eliminated the on/off feature in favor of a gradual apply/release function. It has a 12 pin case connector, extra wire in the transmission to computer harness and different computer to control the new PWM circuit. 3.6 3.6 out of 5 stars (20) $76.59 $ 76. You often can spot TCC problems before they trigger codes by monitoring duty cycle with a scan tool. The difference is the addition of the "Lockup Feel" solenoids (aka.

FOR SALE! Figure 2 shows PWM progression during typical TCC application. Some other info, if leak test isnt accessable. 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. rref-Solenoid charts.indd 77ef-Solenoid charts.indd 77 11/5/06 4:32:43 PM/5/06 4:32:43 PM << /ASCII85EncodePages false /AutoPositionEPSFiles true Other tests can be done, but if you just own a VoltOhmeter, that should be all you would need to perform your testing. # The Lock-Up Feel (LUF) solenoid was probably put in high end Cadillacs for seamless shifting. 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). Has PWM stamped cast in pump.

(913) 851-7711. Pump is the same as '95. VSS (vehicle speed sensor) on 2WD vehicles is in transmission extension housing, on 4WD vehicles the VSS is in transfer-case. 491g Package List: 1 x A Shift Solenoid 1 x B Shift Solenoid 1 x 3-2 Downshift Solenoid 1 x EPC (Pressure Control) Solenoid 1 x TCC/PWM Solenoid T: tcc solenoid (on/off in pump) U: tcc pwm solenoid (valve body) Sometimes these plugs may be stuck, so wiggle them a little to get them free. Here I use Ohms Law for testing. Shift solenoid 2 should be 12-28 Ohms. When the mode switch is closed, auto mode will be used, regardless of what you do with the shift buttons. It is found in both 240 and 260 from 1975 through 1986. * The Pressure Control solenoid controls main line pressure, pulsed at 0-60% duty cycles at 293 Hertz. 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. ]Z1iw'=xz U[!mxx ?b7|9 2xvSs`fQ%]kUu^eZqRc%[|yEO?fOM No other repairs were made and the transmission was not removed from the car. 0000000886 00000 n 0000013697 00000 n Shift solenoid 1 should be 12-28 Ohms. 4L60E 1 4L80E 3 4R100 2 4R70W/AODE 3 4T40E 3 4T45E 3 4T60E 1 4T65E 1 4T80E 3 A140E series 2 A240E series 2 A340E series 2 A340F series 2 A43DE series 2 A440 series 2 . 00. 2011-07-29. Under PWM control, the PCM sends a variable duty cycle to the second solenoid to control the regulated apply valve (Figure 1). ** The TCC is pulsed (frequency is 32 Hertz, with duty cycle varied). 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.

These are simple plugs that have a tab that is easily released. 1 Prong normally open switch. 0000001238 00000 n 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. Many of these modifications can be beneficial, but some can cause unintended complications or downright damage. 0000013511 00000 n All the following graphs were taken on one test drive of a 1998 Camaro with a 4L60-E EC3. (913) 851-7710. store4324@theupsstore.com. The best way to make sure that your shift solenoids are the root cause is to test them. 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. 2 required.No returns on installed electrical components. The 3-2 control valve was changed to the second design valve. 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. When testing your shift solenoids, the first step is to remove the plugs going into the solenoids from the harness. Its the only available modification that both eliminates PWM/EC3 operation and limits converter pressure to acceptable levels. Knowing how and why this happens is the key to avoiding converter failure comebacks which are the product of a modification someone else performed. HW TSg~Y!lMR!AYl I8@0 1nIxh6{J-[*T\Kqg*VN.

This is enough for extra holding power while avoiding the consequences of full line pressure to the TCC piston. Ramping this pressure in stages gives us the smooth operation and improved fuel economy were looking for. 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). They both showed significant wear using a wet-air-test technique. D: pressure control solenoid low . Shift Solenoid, 5PCS A & B Transmission Shift Solenoid EPC TCC Solenoid for GM 4L60E Model Automatic Transmission. When the converter is not locking up you will notice the engines RPMs staying higher under load at highway speeds. The main symptom of a TCC solenoid failure is the converter is not locking up. To avoid the negative repercussions of full line pressure in this circuit while still allowing slightly elevated apply pressures for better performance, Sonnax developed the TCC pressure limiter spring system, which converts the TCC regulator valve into a simple pressure limit valve. However, a 90 elbow, or maybe even some tubing, will be required in most installs to keep the sensor away from the transmission tunnel. 1,031. A friction lining with higher thermal capacity must be used such as the HTS (High Thermal Slipping) linings offered by Sonnax. Works at 16 ohms ONLY Come to my house and try it. 4L60E Performance & Heavy-Duty Transmission Build Guides. When the TCC solenoid receives a signal from the engine control module (ECM), it opens a passage in the valve body and hydraulic fluid applies the TCC. For 1995 and earlier, it should be 7-20 Ohms. 3.5-8.0 Ohms TORQUE CONVERTER CLUTCH SOLENOID Pins E & T 20-40 Phms AUTOMATIC TRANSMISSION OUTPUT SPEED SENSOR (OR VEHICLE SPEED SENSOR) 1260-1540 Ohms The meter should read zero or close to zero. 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). 20-31 ohms 4L70-E Transmission 4L60-E Transmission 4L65-E Transmission While Sonnax makes every effort to ensure the accuracy of technical articles at time of publication, we assume no liability for inaccuracies or for information which may become outdated or obsolete over time. When assessing a shift solenoid issue, there can be a number of things to consider. Troubleshooting based on codes p1860 and p1870.Th. 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. No returns on installed electrical components. Note the linear duty cycle change from 0% (unlocked) to 90% (full lockup), plenty of time to gently apply the clutch without harsh feel or driveline disturbance. Working with transmission builders to ensure they are buying a 4L60-E converter with lining best suited to their particular build or modifications is one of the keys to long converter life and avoiding modification-related comebacks.
