4L60E Tcc Solenoid 1995-02, remanufactured and ready to install. Fits the 4L60E. Ships fast from the USA.
If you are hunting for a TCC solenoid for a 1995-2002 Chevy or GMC truck, a Tahoe or Suburban, an S10 or Blazer, or a Camaro, the complaint is usually the same: the converter will not lock up on the highway, it shudders when it tries, or the engine wants to stall as you roll to a light. This listing carries the TCC solenoid name, but the photo shows a remanufactured early 4L60E valve body with the solenoids and wiring fitted, sold with a 1-year warranty. On a transmission that is now twenty-plus years old, the lockup valves and bores have worn right along with the solenoid, and a complete reman valve body fixes both.
The very first 4L60E units in 1993 and 1994 had no TCC PWM solenoid on the valve body at all; Sonnax's identification guide lists them with four valve body solenoids. In 1995 GM added a pulse-width-modulated TCC solenoid so the computer could feather the converter clutch on rather than snap it closed. That solenoid works together with the on/off TCC solenoid on the internal harness: the on/off unit opens the apply circuit, and the PWM unit controls how quickly and how hard the clutch applies through the TCC regulator valve. Both run on oil from the AFL valve, so a worn AFL or regulator bore makes a good solenoid behave like a bad one.
Start electrical, because it is cheap to rule out. ATRA Technical Bulletin 269 gives the 4L60-E case connector pin map and resistance values, so each solenoid circuit can be measured from outside the pan. A circuit that reads open, shorted or changes when the harness is wiggled is a wiring or solenoid fault. If every circuit is in spec and a scan tool shows lockup commanded but slip stays high, the problem is hydraulic, and that is where a reman valve body earns its price. Our P0740 and TCC solenoid diagnosis guide covers both checks, and if the truck also has a flare on the 3-2 downshift, read the 3-2 downshift solenoid guide before ordering.
The listing says 1995-2002, and that span is not one design. Sonnax breaks it into three valve bodies. The 1995 unit uses metal white PWM solenoids for both TCC and 3-2 control and a non-vented manual valve. From 1996 to 2000 the 3-2 solenoid becomes a white plastic on/off part of 20 to 31 ohms, the TCC PWM becomes gray plastic, and the manual valve is vented. Late in 2000 GM moved to annular lockup, with TCC exhaust ports cast into the top and bottom of the body. Those differences matter, so compare your old valve body with the photo, especially the 3-2 solenoid style and the TCC exhaust ports, or send us your year and VIN. A 1993-1994 or a 2003-and-later transmission is a different part. Browse every early version on the 4L60E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The photo shows a complete remanufactured early 4L60E valve body with solenoids and wiring fitted. Contact us if you want the exact contents confirmed before ordering.
No. Sonnax lists the 1993-1994 4L60E valve body with no TCC PWM solenoid and a different casting, so it is not the same part.
No. The 1995 body uses metal PWM solenoids and a non-vented manual valve, while 1996-2000 uses plastic solenoids and a vented manual valve. Match the photo to your old body or send us your VIN.
Yes. If the converter clutch stays applied as you slow down, it drags the engine down at a stop the same way letting out a manual clutch would.
Use Dexron VI, GM's current service fluid, which is backward compatible with the earlier Dexron fluids these transmissions were built with. Check the level hot.
