4T60E Overhaul Kit 1995, new and ready to install. Fits the 4T60E. Ships fast from the USA.
Looking for a 4T60E overhaul kit for a 1995 or later Buick, Chevrolet, Oldsmobile or Pontiac? This one is listed for the 1995-up 4T60-E and is more than a gasket set. Owners usually land here after a shop has told them the transaxle needs to come out: it slips on the highway, flares before it catches the next gear, thumps into Drive after sitting, or the fluid smells burnt. Per the listing, the box contains Borg-Warner friction plates with matching steel plates, a Transtec soft parts set with the rubber seals and gaskets for the complete overhaul, a new filter and all three bands. That covers the wear parts in one order so the job is not held up waiting on a second shipment.
The 4T60-E is GM's electronically shifted four-speed front-drive transaxle, with a drive chain linking the converter to the gear train. Gear changes are made by clutch packs plus a forward band, a 1-2 band and a reverse band, all applied by line pressure that the computer manages through its solenoids. The seals in this kit are what let each circuit hold that pressure; the frictions, steels and bands are what actually lock the gear members. When the linings wear and the seals harden, apply pressure leaks away and the clutches slip and burn, which then sends debris through the valve body. Replacing seals alone on a slipping unit rarely lasts, which is why a kit that includes the frictions, steels and bands makes sense once the pan shows heavy wear material.
Scan for codes, check the fluid hot, and if possible run a line pressure test. Low line rise has hydraulic causes: Sonnax lists worn boost valves and pressure regulator bores in this valve body that cause exactly the 2nd and 3rd clutch distress a worn unit shows, so new frictions installed over a worn bore can burn again. Pan debris plus slipping confirms the clutches are gone. The 4T65E grew out of this transaxle, so our 4T65E diagnosis guide and pump failure guide are close matches for testing a 4T60-E.
The listing covers 1995 and later 4T60-E transaxles in GM, Chevrolet, Buick, Oldsmobile and Pontiac cars. Sonnax notes a revised 2-3 shift valve and 3-2 manual downshift valve from 1994 on, which is one reason the 1995-up kit is listed separately from earlier units. Some GM cars switched to the 4T65E starting in 1997, and the two look similar from outside, so read the tag on the case before ordering; our identification guide shows where to look. Send us your year and VIN if you want the kit checked against your car. Earlier transaxles should use the 1991-94 4T60E overhaul kit, and the rest of the parts for this family are on the 4T65E and 4T60-E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Per the listing it includes Borg-Warner frictions, steel plates, a Transtec soft parts set with seals and gaskets, a filter and all three bands.
The listing does not mention pistons for this kit. Inspect your pistons for cracks and damaged bonded seals during teardown and replace any that are worn.
It is listed for 1995 and later units. For 1991-94 transaxles use the 1991-94 kit, and send us your VIN if your car is near the changeover.
GM began switching to the 4T65E for 1997, so either is possible. Check the identification tag on the case or send us your VIN before ordering.
Dexron VI. GM designed it to be back-serviceable into transmissions that originally specified Dexron III.
