Every electrical part inside a 1996-2002 GM 4L60E in one box: shift A/B, 3-2, EPC, PWM and TCC solenoids, harness, pressure switch, filter and pan gasket.
If your 1996-2002 Silverado, Sierra, Tahoe, Yukon, Suburban, S-10, Blazer or Camaro is throwing shift solenoid codes, flaring between gears, or dropping converter lockup on and off, the cause is often more than one tired electrical part. This remanufactured kit puts every electrical component on the 4L60E valve body into one box, along with the filter and pan gasket, so the job is done with a single pan drop. The solenoids are original GM units that have been pulled, cleaned and tested, and the listing references GM numbers 24212690 and 24227792.
The 4L60E has no throttle valve cable or governor. The PCM runs everything through the valve body solenoids, and this kit covers all of them:
Also in the box: a shallow-pan filter with its neck seal and a pan gasket.
Pull the codes and note every one, not just the first. Ohm the solenoids through the case connector: ATRA's published 4L60-E chart puts the shift solenoids at roughly 20-40 ohms and the pressure control solenoid at 3.5-8.0 ohms. Then wiggle the harness at the connector while watching resistance. Our 4L60E shift solenoid testing guide walks through the pin map, and the P0748 pressure control guide covers the EPC side. If every circuit reads correctly and the shift problem stays, the valve body bores may be worn, and new solenoids alone will not cure it.
This kit is built for the 1996-2002 pattern 4L60E and 4L65E. Starting with the 2003 model year GM changed the shift solenoid, TCC and harness layout, so 2003-and-later units need a different kit. Check the year on your door sticker and look at the solenoids on your valve body before ordering; if you are unsure, send us the year and VIN and we will confirm it. Other kits for this transmission are on the 4L60E parts page, including the new-solenoid master solenoid kit with harness, filter and gasket.
Drain the fluid, drop the pan and pull the filter. Unplug the harness from each solenoid and the case connector, then pull the shift solenoids, 3-2 solenoid, PWM solenoid, EPC solenoid and pressure switch manifold off the valve body. Lube every new O-ring with ATF before fitting. Route the harness exactly as the original ran, clear of the valve body edges where it can rub, and torque the manifold bolts to spec. Look at the debris in the old pan: heavy clutch material means the unit has problems beyond the electrical side. Install the new filter and gasket, refill with Dexron VI, clear codes and road test through all four gears and lockup. If you want firmer shifts while the pan is down, the TransGo SK 4L60E shift kit goes in at the same time.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Remanufactured. The solenoids are original GM units that were pulled, cleaned and tested. They can arrive with a light coat of oil from testing, which is normal.
No. This kit is for 1996-2002 4L60E and 4L65E units. GM changed the solenoid and harness layout for 2003, so later trucks need the 2003-up kit.
Not always, but the harness is included and is a common cause of intermittent codes on older units. Replacing it while the pan is down avoids chasing a wiring fault later.
Dexron VI ATF. Check the level hot with the engine running in park after the road test.
Clear the codes and drive the truck through all four gears and several lockup cycles so the PCM can adapt shift timing. A scan tool reset of transmission adapts helps if your PCM supports it.
