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. There is an early and a late model of the 4L60E 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technical articles at time of publication, we assume no liability for inaccuracies or for information which may become outdated or obsolete over time. 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. However if they burn out the computer should generate a DTC code. Transmissions plug pin identification 1995 and up. 4L60E transmission solenoids 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. There is no cleaning pulse (dither) every 10 seconds on this transmission (unlike the 4L80E). 0000001056 00000 n If you need to replace your shift solenoids, they are a pretty straightforward piece to remove and install. 35399A 4L60E 4L80E 4T80E Transmission electronic pressure control solenoid 1991-02, 35399B 4L60E 4L65E 4L80E Transmission electronic pressure control solenoid 2003-on. 35393A 4L60E transmission 1-2, 2-3 shift solenoid 1992 & NEWER (2 Required). 35380B 4L60E Transmission output speed sensor 1996-on. 35389D 4L60E Transmission external wire harness repair 1995-2003. 0000001675 00000 n 6)lX>NA}PcjW/h@[ uDRt^6D /{Cx 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). I tried it and got 24 ohms at 20degrees C. Does that sound correct? FYI, since this is a solenoid, it doesnt matter which wire goes where. 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. 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. Simply repeat this process for the other solenoid to verify both are working or not. 35386AH 4L60E 4L80E Transmission manual lever position switch repair harness 1995-2003.

Instead a consistent slip of 20 to 40 RPM is maintained. Luckily, it is pretty straight forward testing and replacing (if need be) 4l60e shift solenoids. There is a common modification for the 4L60-E TCC circuit that causes multiple problems, one of which is TCC friction delamination. Next, take your test leads and connect them to the backside of the solenoid where the electrical prongs are. Switching the TCC abruptly can result in a harsh apply sensation and adds unnecessary stress to driveline components. This adaptive control strategy can provide nuggets of diagnostic gold: as the regulator bore wears, the duty cycle required to keep slip in the appropriate range increases. The TCC control solenoid was changed to a 20-31 OHM solenoid, from the previous 10-15 OHM solenoid. The rate of increase of the duty cycle controls the TCC apply rate. 4L60E Shift Solenoid A&B Transmission Filter Gasket kit Compatible with Cadillac-Escalade ESV EXT, Chevrolet-Blazer Camaro Avalanche Silverado Avalanche 1500, Buick-Rainier, Replace 24230298 .
