4L60E Solenoid Kit 2006-08, new and ready to install. Fits the 4L60E. Ships fast from the USA.
A 2006, 2007 or 2008 Silverado 1500, Sierra 1500, Tahoe, Yukon or Suburban that starts in 2nd, will not upshift, drops into limp mode, or sets a shift solenoid code is a classic 4L60E solenoid problem. This new solenoid kit is built for the 2006-2008 4L60E and carries a 1-year warranty, so you can replace the electrical side of the valve body in one job instead of swapping one solenoid at a time and hoping.
The 4L60E is a two-shift-solenoid design. The 1-2 shift solenoid (A) and 2-3 shift solenoid (B) are simple on/off valves, and the computer selects each gear by the combination it turns on: both on for 1st, A off and B on for 2nd, both off for 3rd, and A on with B off for 4th. Alongside them, the pressure control solenoid sets line pressure for shift firmness, the TCC solenoids handle converter lockup, and the 3-2 control solenoid manages downshift timing. All of them are fed by regulated oil from the actuator feed limit valve. If one coil weakens or a solenoid seat leaks, the computer commands a gear the hydraulics cannot produce, and it either flags a code or defaults to a failsafe gear.
Solenoid codes are just as often caused by wiring. Test at the transmission case connector first: on the 4L60E the 1-2 and 2-3 shift solenoids are specified at roughly 20-40 ohms and the pressure control solenoid at about 3.5-8 ohms. A reading out of range, or one that changes as you flex the harness, tells you where the fault is. A poor terminal crimp in the harness can set several solenoid codes at once, which is a different repair. Our guide to 4L60E shift solenoids A and B and codes P0753/P0758 walks through the test, and the P0748 pressure control solenoid guide covers the EPC side. If the electrical checks pass and the shift problems remain, worn valve body bores are the next suspect, and new solenoids will not fix those.
This kit is listed for the 4L60E in 2006-2008 applications: the Chevrolet Silverado 1500, Tahoe and Suburban, GMC Sierra 1500 and Yukon, and other GM models that used this transmission in those years. GM changed the internal harness and solenoid hardware more than once through the 4L60E run, and kits for 1993-2002 and 2003-2005 units are different. Compare your solenoid connectors and the internal harness against the photos, and if you have any doubt send us your year and VIN before ordering. Kits for other years and the matching valve bodies are listed on our 4L60E parts page. The listing does not break down the individual pieces included, so contact us if you need a specific solenoid confirmed.
If the fluid was burnt or full of debris, consider the whole valve body: the 2003-2008 4L60E valve body assembly covers these years.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2006-2008 4L60E applications, which includes the Silverado 1500, Sierra 1500, Tahoe, Yukon and Suburban with that transmission. Match your connectors to the photos or send us your year and VIN to confirm.
Do not assume so. GM changed the harness and solenoid hardware across 4L60E years, which is why kits are sold by year range. Use the kit for your year, or verify every connector before installing a different one.
Usually not. With the pan and filter off, the solenoids come out of the valve body with their clips or bolts. Check the internal harness while you are in there.
Several solenoid codes at once often point to a wiring or connector fault rather than multiple failed solenoids. Test resistance at the case connector and inspect the harness before replacing parts.
Use Dexron VI ATF. After the install, clear codes and run the transmission adapt reset and relearn with a scan tool so the computer does not keep compensating for the old worn solenoids.
Yes, the kit is new and carries a 1-year warranty.
