4L60E Clutch Drum 1987, remanufactured and ready to install. Fits the 4L60E. Ships fast from the USA.
If you are rebuilding the four-speed overdrive automatic out of a 1987 Chevrolet or GMC C/K pickup, Suburban, Blazer, S10, Camaro or Corvette, you are working on what GM still called the 700-R4 that year. The electronic 4L60E name did not arrive until the early 1990s, but the rotating drums carry the same basic layout through the whole family, which is why this part is filed with our 4L60E hard parts. This listing is a remanufactured clutch drum for 1987 applications, priced for the rebuilder who opened the case, found a cracked or scored drum, and does not want to put fresh clutches into a damaged housing.
Two drums spin inside this transmission, and both get called a clutch drum at the parts counter. The input housing is driven by the turbine shaft and holds the forward, overrun and 3-4 clutch packs. Behind it, the reverse input drum carries the reverse input clutch on the inside, while its smooth outer wall is the surface the 2-4 band clamps to for 2nd and 4th gear. Each pack is applied by its own piston, fed through sealing rings and drilled passages, so a cracked wall, a worn bushing or a scored seal bore lets apply oil escape and that one clutch starts to slip. The photo for this listing shows a smooth-walled drum shell with slotted lugs at the open end, a piston and clutch assembly, steel plates and a retaining ring. Compare it carefully with the drum you pulled, because the two drums are not interchangeable.
Rule out low fluid and low line pressure first, since they will slip a healthy drum. On the bench, clean the drum and air-check each piston: you should hear a firm apply and no hissing leak-down. Look at the snap ring grooves and lug area for cracks and run a fingernail across the band surface. Sonnax warns that an old band compresses the reverse drum and leaves a slight dish, which is why a used drum should not be paired with a wider band. If your complaint is no Reverse, read our low-reverse clutch failure guide before blaming the drum; if it is repeat 3-4 burnup, our 3-4 clutch pack diagnosis guide walks through the pressure and leak checks that usually find the real cause.
This listing is specified for 1987. GM made running changes to the 700-R4 every few model years, including clutch counts, piston designs and bushing details, so a 1987 drum is not a guaranteed match for a 1982 or a 1993 unit. Match the drum style, spline count, lug pattern and overall height to your original, or send us the year, vehicle and VIN and we will check it before it ships. If your rebuild needs the input housing rather than this drum, the 1987 input drum is listed separately, and every year-specific drum and kit we carry is on the 4L60E and 700-R4 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. In 1987 GM called it the 700-R4, a hydraulically controlled four-speed. The 4L60E came later with electronic shift control, but the internal drums and clutch layout follow the same family design, so parts for both are grouped together.
The listing calls it a clutch drum for 1987, and the photo shows a smooth-walled drum shell with slotted lugs plus a piston, clutch and steel assembly. Compare it with the part you removed, and if you are unsure, send us the year, vehicle and VIN before ordering.
New frictions, steels and piston seals for the pack inside it, the sealing rings on the shaft that feeds it, and the bushing if it is worn. A new 2-4 band is a good idea if the drum surface was damaged.
It is better not to. A worn band has already conformed to the old drum surface. Install a new band of the original width and adjust or select the servo apply pin per the service manual.
It was filled with Dexron II from the factory. Dexron VI is the current GM service fluid that replaces earlier Dexron grades in these units.
