Solenoid/Switch Resistances Part of the 4L60E electrical diagnosis should include checking the electrical resistance of solenoids and other . Later models apparently use 614 Hertz. If it reads a number, for example 5 ohms, then you will need to subtract 5 ohms from each reading. Instead, a consistent slip of about 20 to 40 RPM is aimed for under most operating conditions. If the solenoid works, youll hear a clicking sound when you go to attach the 2nd wire to the battery. Get directions, store hours & UPS pickup times. Locally owned and operated. No returns on electrical components.Use product # 35391A. 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. Helps cure: TCC apply concerns; Overheated converter; Loss of lube oil; TCC Solenoid Snout Kit 77942-02K. They both showed significant wear using a wet-air-test technique. if you do not see what you need in our ebay store please message us and we will list it for you on ebay . 4L60-E PWM Application Sample As a further effort to improve fuel economy and prolong the life of transmission and engine components, PWM control evolved into EC3. How Much Power Will A Stock 4l60e Handle? 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. 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). VSS (vehicle speed sensor) on 2WD vehicles is in transmission extension housing, on 4WD vehicles the VSS is in transfer-case. There is a common modification for the 4L60-E TCC circuit that causes multiple problems, one of which is TCC friction delamination. This is especially true if you have a cable speedometer, the cable could be binding up. 137th & Metcalf. I believe that this is the only way to test your solenoids on or off the vehicle. 4L60E Transmission Master Solenoid Kit TCC EPC PWM Shift 3-2 Harness for All GM 2003-2005. 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. With anti-drainback valve. Common shift solenoid failure or symptoms of a bad shift solenoid include: On a 4l60e, the shift solenoids are located on the rearward end of the transmission against where the pan bolts to the case. This modification allows full line pressure into the apply circuit, up to 140 psi under load. The valves and solenoids remain (virtually) the same as with PWM operation, but the control strategy and TCC lining have again undergone changes. A friction lining with higher thermal capacity must be used such as the HTS (High Thermal Slipping) linings offered by Sonnax. You often can spot TCC problems before they trigger codes by monitoring duty cycle with a scan tool. 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). 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%. . 35394B 4L60E Transmission 3-2 down shift solenoid 1996-ON. None of the above categories describe me. Grey connector, 10-15 ohms44390 may also be used.No returns on electrical components. Front pump internal passages different to match new TCC strategy. 1996: The 3-2 downshift strategy was changed to an on /off arrangement. 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. Before testing, touch the test leads together. MegaShift has a line pressure sensing/logging function built it. 0000001258 00000 n
Luckily, it is pretty straight forward testing and replacing (if need be) 4l60e shift solenoids. The required fix was to overbore the TCC regulator valve and the AFL valve and replace them with oversize valves. For 1996 and up, the 3/2 downshift solenoid should be 12-28 Ohms.

Ramping this pressure in stages gives us the smooth operation and improved fuel economy were looking for. 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. You are using an out of date browser. 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. The TCC PWM solenoid should be 7-20 Ohms. Fluid from various hydraulic control circuits is fed to this the pressure switch manifold which allows the ECU to determine which gear the shift lever is currently shifted into (not necessarily the actual gear the transmission is in). (Grey Connector). If you apply ground or +12 to the wrong wire, you could fry the ECM (computer). C: pressure control solenoid high . TCC PWM) solenoid valve at approximately 90 percent duty cycle. 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. The ECU also senses a brake switch and turns off the TCC solenoid whenever brakes are applied. With the ECCC system, the pressure plate does not fully lock to the torque converter. If the mode switch is open, pushing either the upshift button or downshift button will put you in manual mode (and pushing both OR switching the mode select switch to auto will put you back in auto mode). 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 If you need printing, shipping, shredding, or mailbox services, visit us at 13725 Metcalf Ave. Torque Converter Clutch Solenoid Valve Testing & Replacement P0741 / P2769 / P2770 CarsNToys 187K subscribers Subscribe 2.2K Share 502K views 3 years ago #torqueconverter Today we'll be dealing.

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. No returns on electrical components. The valves and solenoids remain (virtually) the same as with PWM operation, but the control strategy and TCC lining have again undergone changes. There is an early and a late model of the 4L60E transmission. 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. Contact Us. The TCC lining also was changed, from paper to a high-carbon content lining to stand up to the extra friction and heat generated during PWM operation. Shift solenoid 1 should be 12-28 Ohms. rockbuggy84 said: USA TRANSMISSION PARTS 4l60E 4L65 Solenoid Kit 6pc (EPC A&B SHIFT 391484532439 While you could try to "poke" into the wiring to diagnose the solenoid, I wouldn't recommend it. E: ignition power feed from TCM to solenoids . 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. The early 4L80E pressure control solenoid is PWM at 293 Hertz (same as the 4L60E). The easiest way to identify the valve is, the second design valve will fall out as soon as the solenoid is removed. Until engine temps reach a certain point, the TCC solenoid will not allow for lock up. 4l60e Shift Solenoid Guide When your 4l60e starts to act up and not shift correctly, one very likely culprit is the shift solenoids. This is the maximum clamping power available without causing the negative results associated with full line pressure to the TCC. TCC solenoid remains 10-15 Ohms, which is the same as the '95 arrangement. The main symptom of a TCC solenoid failure is the converter is not locking up. 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. 6)lX>NA}PcjW/h@[ uDRt^6D
/{Cx It has a 12 pin case connector, extra wire in the transmission to computer harness and different computer to control the new PWM circuit.
