4L65E Tcc Solenoid 2009, new and ready to install. Fits the 4L65E. Ships fast from the USA.
This is the late-style TCC enable solenoid and internal wiring harness for a 2009 GM 4-speed automatic, cross-referenced to GM 24237980. It is what you want if a late Silverado, Sierra, Express or Savana with a 4L60E-family transmission has set P0741, gives a harsh 1-2 upshift along with the check engine light, or will not lock the converter at highway speed. Unlike a full master kit, this is the one assembly GM itself singled out on later trucks: the harness and the TCC enable solenoid, sold as a pair because they fail as a pair.
On the late 4L60E-family transmissions, the TCC enable solenoid is permanently wired into the internal harness. When the control module wants lockup, it energizes the enable solenoid, which sends oil to stroke the converter clutch valve in the pump cover; a separate PWM solenoid then controls how firmly the clutch applies. The harness also carries the circuits for the shift solenoids, the pressure control solenoid and the pressure switch, so a chafed wire or tired terminal in this one part can upset shifting as well as lockup.
GM Preliminary Information PIP5009F covered 2012 Colorado, Canyon, Express, Savana, Silverado and Sierra trucks with the 4L60E (M30) built after October 1, 2011, with a MIL, P0741 and a harsh 1-2 shift. It told technicians to replace the TCC enable solenoid and wire harness, part number 24237980, any time the transmission is opened for repair. The same bulletin gives a quick way to avoid replacing a good unit twice: read the five-digit date code on the solenoid body. GM states that solenoids built on or after April 4, 2012 do not need replacing. That bulletin is written for 2012 trucks, but it is the clearest documentation of how this harness and solenoid fail and how GM services them.
Verify the code with a scan tool and clear it, then drop the pan. GM's procedure has you remove the old enable solenoid and harness and stroke the converter clutch valve in the pump cover: it should move freely at least 3/8 inch. If it sticks, the valve and bore need cleaning or repair, and a new harness alone will not cure the code. With the harness out, compare its condition and the solenoid date code. Our Silverado 1500 4L65E shift problems guide and the speed sensor symptoms guide help rule out other causes of harsh shifts and false slip readings.
The listing is for a 2009 4L65E and carries the 24237980 reference. GM used several harness numbers over the life of the 4L60E family, and earlier trucks used different connectors and EPC solenoids, so do not assume an older truck takes this part. Match the connector shapes and the solenoid in the photo to your old harness, check that the case connector is the same, or send us your year and VIN to confirm. Earlier trucks should look at the 2003-2007 TCC solenoid instead, and the rest of the late parts are on the 4L65E collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Both. The photo shows the internal wiring harness with the TCC enable solenoid attached, which is how GM supplies part 24237980.
Do not assume so. Earlier trucks used different harness numbers and connectors. Compare your old harness to the photo or send us your VIN.
On many late GM 4-speed trucks it is. GM bulletin PIP5009F pairs those symptoms with this harness and solenoid, but it also has you check that the converter clutch valve in the pump strokes freely at least 3/8 inch.
Read the five-digit date code on the solenoid body. GM says solenoids built on or after April 4, 2012 do not need replacement.
Dexron VI ATF. Check the level hot after the pan is refilled.
