4T60E Tcc Solenoid 1997, new and ready to install. Fits the 4T60E. Ships fast from the USA.
If a late-1990s GM front-drive car, such as a Buick LeSabre or Park Avenue, Pontiac Bonneville or Grand Prix, Oldsmobile 88 or Chevrolet Lumina, shudders under light throttle at highway speed, drops out of lockup once it is hot, or keeps setting a converter clutch code, the torque converter clutch (TCC) PWM solenoid is one of the cheapest parts to rule out. This listing is a single new solenoid in GM Genuine Parts packaging, part number 24227747 (OE reference 24214974), which the listing describes as the torque converter clutch pulse width modulation solenoid. It is not a full solenoid set, so if you want every coil on the valve body replaced, look at the four-piece kit linked below.
The 4T60-E controls lockup with two parts working together. An on/off TCC solenoid opens the converter clutch circuit when the computer decides the car is warm and cruising, and the PWM solenoid then pulses many times per second to ramp apply pressure up gradually. That ramp is what makes a healthy lockup feel like a slight RPM drop rather than a bump. When the PWM solenoid sticks, loses its internal seal or its screen clogs, apply pressure wanders, the clutch slips and glazes, and the converter and fluid overheat. GM carried the same control idea into the 4T65-E that replaced this unit, and the listing shows this PWM solenoid also serving several later GM transmissions.
Check the fluid first. If it smells burnt or carries friction material, the converter clutch lining may already be damaged and a solenoid alone will not cure the shudder. Measure the solenoid resistance and compare it with the service manual value, and with a scan tool watch commanded lockup against actual slip at a steady 50 mph. Keep the valve body in mind too: Sonnax lists the same 39, 740 and 1870 codes, hot drop-out and shudder for a worn TCC apply valve bore on 1996-and-earlier 4T60-E units, so a new solenoid on a worn bore can leave the problem in place. Our solenoid symptoms guide and the GM front-drive transmission diagnosis guide cover the test sequence for this family of transaxles.
This page covers the 1997 4T60E. The listing lists 1997-2011 GM applications and cross-references 74418E, D74418E, 24212690, 24227747 and 24227792 among others, which tells you GM used the same PWM solenoid across several transmissions in those years. Because the 4T60-E saw running changes through the 1990s, pull your old solenoid and compare the connector and body shape with the photo, or send us your year and VIN before ordering. For the whole lockup and shift set in one box, the 4T60E TCC solenoid kit includes the on/off TCC, PWM and both shift solenoids, and the 4T65E and 4T60E parts page lists everything else for the family.
If the transmission also slips between gears, the solenoid is only part of the story; a 4T60E banner rebuild kit covers the seals and frictions for a full overhaul.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A single new GM TCC PWM solenoid, part number 24227747 with OE reference 24214974, in GM Genuine Parts packaging. If you want the on/off TCC and shift solenoids as well, choose the four-piece 4T60E TCC solenoid kit.
The listing lists 1997-2011 GM applications including the 4L60E, 4L65E, 4T65E and 4T40E. Running changes exist, so match your old solenoid's connector and part number, or send us your year and VIN.
It fixes shudder caused by poor lockup pressure control. Shudder can also come from a worn converter clutch lining or a scored TCC apply valve bore, so check the fluid and the valve bore before deciding the solenoid is the only cause.
The unit was filled with Dexron III when new. GM's Dexron VI is designed to be back-compatible with Dexron III applications, so Dexron VI is the fluid to use today.
At minimum the solenoid O-ring and the side cover gasket. On a high-mileage unit, many builders change the on/off TCC and shift solenoids at the same time, since they are the same age and the cover is already off.
