4L80E Tcc Solenoid 1997-2002, remanufactured and ready to install. Fits the 4L80E. Ships fast from the USA.
A 1997-2002 Silverado or Sierra 2500/3500, Suburban 2500 or Express van that shudders as the converter tries to lock between 40 and 60 mph, cruises a few hundred RPM higher than it should, or keeps setting P0741 or P1870 sends most owners shopping for a TCC solenoid. This listing is filed under that name, but the photo shows what you actually receive: a complete remanufactured 4L80E valve body referenced to casting 24204267, with the TCC solenoid, both shift solenoids and the pressure control solenoid already mounted. If the lockup problem lives in the valve body bores rather than the solenoid coil, this is the part that ends it. If you only want a loose solenoid, ask us before ordering and we will point you to the right single piece.
The torque converter clutch solenoid sits on the valve body and, when the computer energizes it, routes oil to the converter clutch apply circuit so the engine and transmission turn as one at cruise. The solenoid can only send what the valve body feeds it. Solenoid feed oil comes from the actuator feed limit (AFL) valve, and Sonnax documents that this valve bore wears on the 4L80-E, which drops feed pressure to every solenoid on the body. A healthy new solenoid on a worn AFL bore still gives a soft, slipping apply. That is why a full valve body with the TCC solenoid on it is often the cheaper repair in the long run on a truck with this many miles. This unit is remanufactured with an updated TCC regulator valve, an updated AFL valve and updated shift valve springs, then tested on solenoid and valve body test stands before it ships. It does not include the pressure switch manifold, so plan to move your existing one over or replace it separately.
Scan for codes and watch TCC slip RPM with lockup commanded on a loaded grade. Ohm the circuit at the case connector: our 4L80E shift solenoid guide lists the TCC solenoid at 10 to 14 ohms and the shift solenoids at 18 to 24, and notes that terminal E is one ignition feed shared by both shift solenoids and the TCC solenoid, so a bad feed can mimic two failed parts. If the readings are in range and the slip is still there, the problem is hydraulic. Our 4L80E common problems guide walks through the AFL bore vacuum test and the converter code thresholds in more detail. A converter whose clutch lining is burned will still slip with a perfect valve body, so rule that out too.
The listing covers the 1997-2002 4L80E and references casting 24204267, the GM HD application behind the 2500 and 3500 Chevrolet and GMC pickups, Suburban 2500 and Express and Savana vans of those years. The 4L80E was revised more than once, with a separate early valve body before 1997 and a different internal harness and solenoid set from 2004 on, so check the casting number cast into your old valve body before ordering. If you cannot read it, send us the year and VIN and we will match it. Every other 1997-2002 part is listed in our 4L80E parts collection.
The valve body comes out with the pan off and the transmission in the vehicle. Disconnect the internal harness at each solenoid, note the manual valve link, and keep the checkballs in the spacer plate or case where they belong when the old body comes down. Run the bolts down in a pattern to spec rather than one corner at a time, since a warped body causes cross-leaks. Inspect the internal harness for heat-cracked insulation; if it is brittle, replace it with the 4L80E internal wiring harness for 1994-2003 while the pan is down. Fit a new filter and pan gasket kit, refill with Dexron VI (it is back-serviceable for the Dexron III these units shipped with), then clear codes and drive through several lockup cycles to confirm the TCC holds.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The photo shows a complete remanufactured 4L80E valve body, referenced to casting 24204267, with the TCC, shift and pressure control solenoids mounted. If you only need the solenoid itself, contact us before ordering.
It is listed for 1997-2002 4L80E applications in the GM 2500/3500 pickups, Suburban 2500 and Express/Savana vans. Match the casting number on your old valve body to 24204267, or send us year and VIN to confirm.
P1870 sets when converter slip stays above 180 RPM for 7 seconds or TCC duty cycle passes 50 percent. If the solenoids ohm in range, worn valve body feed circuits are a common cause and this assembly addresses them. A converter with a burned clutch will still slip, so confirm that too.
Use Dexron VI ATF. It is approved as back-serviceable for the Dexron III these 1997-2002 units originally used. Replace the filter and pan gasket at the same time.
No. The valve body is supplied with solenoids but without the pressure switch manifold, so transfer your original one or replace it separately if it is leaking or setting codes.
