4T60E Planetary 1995, used and ready to install. Fits the 4T60E. Ships fast from the USA.
A 1995 Buick LeSabre or Park Avenue, Oldsmobile 88, Pontiac Bonneville or Chevrolet Lumina with the 4T60E that grinds or whines under load, loses a gear, or coughs up bronze and steel flakes onto the pan magnet often has a damaged gear-train shell or a worn bushing riding inside it. This listing is a used original GM 4T60E planetary part for 1995. The photo shows a sun gear with a bronze bushing pressed in its bore, joined to a smooth drum shell, pictured beside a thrust bearing. At this price it is a practical way to replace one damaged gear-train piece on a known 1995 unit rather than buying a full hard-parts set.
The 4T60E builds its four ratios from an input planetary set and a reaction planetary set, followed by a planetary final drive feeding the differential. A sun gear sits at the center of a set and the pinions of the carrier walk around it. Some sun gears are driven, some are held still, and a shell like this one ties a sun gear to the member that holds or drives it. The bushing in the bore keeps the gear centered on the shaft it rides on, and the thrust bearing takes the side load that helical gears push along the shaft every time the car accelerates or coasts. When that bushing wears, the sun gear rocks off center, the pinions mesh unevenly, and the teeth or splines wear fast.
Start with the pan. Bronze color in the debris points straight at bushings, and this part has one. With the unit disassembled, slide the sun gear onto its mating shaft and feel for side-to-side play; it should turn smoothly with no rocking. Look at the splines for twisting or chipped teeth, and check the shell for cracks at the weld or heat bluing. Our 4T65E common problems guide covers the same diagnosis on the successor transaxle, and the pump failure guide explains why a weak pump starves lube to bushings like this one.
The listing fits the 1995 4T60E. GM made running changes to this transaxle through the decade, and the 4T65E began replacing it in 1997, so a mid-1990s car could be built with different internals than the year suggests. Hold your old shell next to the photo and match the sun gear tooth count, the spline count on the inside, and the shell length and diameter before ordering, or send us your year and VIN to check. If you need the carrier rather than this part, see our remanufactured 4T60E planetary carrier. All 4T60E and 4T65E parts are on the 4T65E family parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is a used original GM 4T60E planetary part listed for 1995. The photo shows a sun gear with a bronze bushing joined to a drum shell, pictured beside a thrust bearing. Compare it with your old part before ordering, and plan on new thrust bearings regardless.
It is listed for 1995. Neighboring years may share it, but GM made running changes, so match tooth count, splines and shell size with your old part or send us your VIN.
Do not assume so. The 4T65E replaced the 4T60E from 1997 with heavier gear-train parts. Read the ID tag on your case before ordering.
Usually poor lubrication from a worn pump or plugged cooler, or debris from another failure passing through the bore. Fix the cause and flush the cooler, or the replacement will wear the same way.
Dexron VI is the current service fill and is back-serviceable into older Dexron transaxles like the 4T60E. Set the level at operating temperature.
