When assessing a shift solenoid issue, there can be a number of things to consider. The difference is the addition of the "Lockup Feel" solenoids (aka. 1,031. TCC lock-up solenoid is normally only energized in 4th gear, if the transmission temperature is above 250F it will energize it in 2nd and 3rd as well. # The Lock-Up Feel (LUF) solenoid was probably put in high end Cadillacs for seamless shifting. 137th & Metcalf. Under some high-torque or freeway speed situations, the PCM will increase duty cycle to 98% to fully lock the TCC. The image below shows the locations of various solenoids. The 4l60e TCC Solenoid is located on the front passenger side of the transmission near the valve body. 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. More Information, No returns on installed electrical components, 11 prong connectorNo returns on electrical components, 4L60E 4L80E Transmission wire harness repair, 4L60 4L65E Transmission wire harness repair.Repair kit for MLPS/PRNDL switch, 11 pin single connector (for 77974A NSS). 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%. The TCC PWM solenoid should be 7-20 Ohms. Transmission Solenoid Testing (Ohms Law) - Transmission Repair Automatic Transmission 163K subscribers 482K views 9 years ago Transmission Solenoid Testing. 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. For these reasons the PWM control strategy was introduced. Central Oklahoma. 0000000886 00000 n
The cost associated with replacing a 4l60e TCC solenoid is not too bad, especially if youre comfortable doing it yourself. 1-35399A (3.5 to 4.66 OHM) EPC solenoid 2-35394A (9 to 14 OHM) PWM 3-2 downshift solenoids. Later models apparently use 614 Hertz. One very easy way to test your shift solenoids is actually with a simple 9v battery to see if the solenoids are being activated. 0000014362 00000 n
DTC will set if one of the following conditions occurs for 5 seconds: *Control module commands solenoid on and voltage remains high (battery voltage) *Control module commands solenoid off and voltage remains low (zero volts)" But I wouldn't be surprised if there are other issues that can throw this code. No machining required. rockbuggy84 said: But on/off operation had some shortcomings. Instead, a consistent slip of about 20 to 40 RPM is aimed for under most operating conditions. . 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. A second TCC solenoid was added to control the regulated apply valve. Many of these modifications can be beneficial, but some can cause unintended complications or downright damage. You often can spot TCC problems before they trigger codes by monitoring duty cycle with a scan tool. The rate of increase of the duty cycle controls the TCC apply rate. This is especially true if you have a cable speedometer, the cable could be binding up. if you do not see what you need in our ebay store please message us and we will list it for you on ebay . HW TSg~Y!lMR!AYl
I8@0 1nIxh6{J-[*T\Kqg*VN. 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). A friction lining with higher thermal capacity must be used such as the HTS (High Thermal Slipping) linings offered by Sonnax. 35394B 4L60E Transmission 3-2 down shift solenoid 1996-ON. * The Pressure Control solenoid controls main line pressure, pulsed at 0-60% duty cycles at 293 Hertz. Or fastest delivery Wed, Mar 22 . C: pressure control solenoid high . Luckily, it is pretty straight forward testing and replacing (if need be) 4l60e shift solenoids. 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). However, when they go bad, you will notice very quickly. 35386BH 4L60 4L65E Wire Harness Repair 2004-UP (4L80E 01-UP). .

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. This eliminates slip and prevents excess heat during high-load conditions. we are a transmission one stop transmission and transmission parts store. Another symptom of a failed TCC solenoid is a fault code. OEM White connector. 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. This blocking modification has been embraced by some builders of high performance or heavy towing units, even without a trouble code to conquer. Max. After you have attached your test leads, simply connect them to the 9v battery one at a time. The meter should read zero or close to zero. E: ignition power feed from TCM to solenoids .

When the mode switch is closed, auto mode will be used, regardless of what you do with the shift buttons. It's a 0.5-4.5 Volt output (accuracy &plusminus;5 psi), and has just a three wire hookup: It has a 1/8 NPT fitting - the same as the transmission port. If you apply ground or +12 to the wrong wire, you could fry the ECM (computer). I am interested in enhancing my vehicles performance. You are using an out of date browser. 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".). The main symptom of a TCC solenoid failure is the converter is not locking up. They both showed significant wear using a wet-air-test technique. 7798001K 4L60E,4L65E,4L70E BRACKET WIRE HARNESS CONNECTOR, 7794201K 4L60, 4L60-E '96-EARLIER SOLENOID SNOUT, TCC, 7794202K 4L60-E, '97-UP, PWM UNITS SOLENOID SNOUT W/CHECK VALVE. 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. The required fix was to overbore the TCC regulator valve and the AFL valve and replace them with oversize valves. The TCC PWM solenoid should be 7-20 Ohms. (913) 851-7711. When the converter is not locking up you will notice the engines RPMs staying higher under load at highway speeds. When your 4l60es TCC solenoid begins to fail, there are a number of obvious signs. If it is not, then simply replace it. 6)lX>NA}PcjW/h@[ uDRt^6D

MegaShift has a line pressure sensing/logging function built it. The valves and solenoids remain (virtually) the same as with PWM operation, but the control strategy and TCC lining have again undergone changes. 4L60E Performance & Heavy-Duty Transmission Build Guides. J-Type Overdrive Basic Rebuild Guide for M41 & M46 Transmissions. On these vehicles the VSS is part of the speedometer head. Common issues that may cause you to believe the 1-2 or 2-3 shift solenoids are failing are a bad accumulator, stuck shift valve, just to name a few. Simply repeat this process for the other solenoid to verify both are working or not. 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. 0000002609 00000 n
