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). In contrast, OE apply pressures range from about 60 to 80 psi. 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? How Much Power Will A Stock 4l60e Handle. And while fuel economy improves with TCC operation, it can be increased further with a different control process. A second TCC solenoid was added to control the regulated apply valve. 0000002609 00000 n The easiest way to identify the valve is, the second design valve will fall out as soon as the solenoid is removed. With some high torque or high vehicle speeds, the converter clutch is fully locked by the OEM ECU. 35380B 4L60E Transmission output speed sensor 1996-on. The valves and solenoids remain (virtually) the same as with PWM operation, but the control strategy and TCC lining have again undergone changes. 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. This modification allows full line pressure into the apply circuit, up to 140 psi under load. When assessing a shift solenoid issue, there can be a number of things to consider. When the PCM determines EC3 clutch application is necessary, the duty cycle for the regulator solenoid is raised in rapid steps to around 50%, providing enough pressure for converter apply to begin. Voltage drop testing is also accurate but you also need to put your component under load.

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technical articles at time of publication, we assume no liability for inaccuracies or for information which may become outdated or obsolete over time.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 friction lining with higher thermal capacity must be used such as the HTS (High Thermal Slipping) linings offered by Sonnax. The M46 is the younger sibling of the venerable M41 found in 1800 and in some . 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 required fix was to overbore the TCC regulator valve and the AFL valve and replace them with oversize valves. 0000009817 00000 n The valves and solenoids remain (virtually) the same as with PWM operation, but the control strategy and TCC lining have again undergone changes. One very easy way to test your shift solenoids is actually with a simple 9v battery to see if the solenoids are being activated. Under PWM control, the PCM sends a variable duty cycle to the second solenoid to control the regulated apply valve (Figure 1). At WOT (wide open throttle), the duty is at min (0% or off).

This eliminates slip and prevents excess heat during high-load conditions. 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. 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 TCC PWM solenoid should be 7-20 Ohms. Earlier transmissions won't have this solenoid, so checking it will show an open circuit. When the PCM de-energized the solenoid, the valve returned, allowing converter feed oil to switch back to the release circuit and cutting off apply pressure. 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. *** The 3-2 Sol is pulsed at 50 Hertz, 0% duty in 1st, 90% duty in all other gears. 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. $129.00 $ 129. 35386A 4L60E 4L80E Transmission (MLP) manual lever position switch 1995-2003. 4L60E transmission solenoids You often can spot TCC problems before they trigger codes by monitoring duty cycle with a scan tool.
