4L60E Solenoid Kit 2008, remanufactured and ready to install. Fits the 4L60E. Ships fast from the USA.
A 2008 Silverado 1500, Sierra 1500, Tahoe, Yukon or Suburban with a 4L60E that suddenly shifts hard, hangs in one gear, will not lock up on the highway, or flashes a shift solenoid code is a strong candidate for a solenoid refresh. This remanufactured kit is listed specifically for the 2008 4L60E and comes with a 1-year warranty, giving you a tested set of solenoids for that model year.
Inside the pan, the valve body carries every electrical control the transmission has. Shift solenoids A and B are on/off valves whose combination picks the gear. The pressure control solenoid takes a varying current from the computer and turns it into line pressure, so it decides how firm each shift is and how much clamping force the clutches see. The TCC solenoids apply the converter clutch at cruise, and the 3-2 control solenoid manages the downshift into third. All of them live on oil supplied by the actuator feed limit valve. In a 2008 truck that has spent years at highway speed in lockup or pulling a trailer, the coils, seats and O-rings have taken the same heat, which is why a full kit makes more sense than one-at-a-time replacement.
Diagnose the circuit before the part. Measure each solenoid at the case connector, inspect the pins for corrosion, and look at the harness where it crosses the frame and exhaust. A single shared-feed wiring fault can set several solenoid codes at once, and ATRA has published exactly that case on the 4L60E. Our shift solenoid A and B guide for P0753 and P0758 lays out the test sequence, and the EPC pressure control solenoid explainer covers why shift feel changes as that solenoid wears. If the electrical side passes, the valve body bores are next in line.
This kit is listed for the 2008 4L60E. That covers the GM trucks and SUVs that still used the 4L60E that year, but by 2008 GM was also building the 4L65E and 4L70E in related vehicles, and those are not automatically the same parts. Check the RPO code on your glovebox or door-jamb label to confirm you have a 4L60E (RPO M30), then compare the solenoid bodies and connectors in the photos with yours. If you are unsure, send us your VIN and we will check it. The listing does not list every included piece, so ask if one solenoid needs confirming. Our 4L60E parts page has kits for other years, and the 7-piece master solenoid kit for 1993-2008 is another route.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Check the RPO codes on the label in the glovebox or door jamb. The 4L60E is RPO M30. If you see a different transmission code, send us your VIN so we can point you to the right kit.
It is remanufactured and covered by a 1-year warranty.
If the harness insulation is brittle or the connectors show heat damage, yes. GM service guidance for later 4L60E family units calls for harness replacement during transmission repairs.
Not always. On the 4L60E, P0741 is frequently caused by valve body bore wear in the converter circuit. Test the solenoid circuit first, and vacuum test the valve body if the electrical checks pass.
Refill with Dexron VI, check the level at operating temperature, clear stored codes, reset the shift adapts with a scan tool, and road test through every gear and lockup.
