4T65E Overhaul Kit 1999-2002, new and ready to install. Fits the 4T65E. Ships fast from the USA.
This is a complete overhaul kit for the GM 4T65E as it was built for Volvo, listed for 1999-2002 units. The best-known application is the six-cylinder Volvo S80, which used this GM transaxle instead of a Volvo-sourced gearbox. If your car now flares between gears, slips once it is hot, takes a long time to pick up Drive, or the fluid came out dark and full of friction material, the unit has to come apart, and this box covers almost everything that wears inside it. It is a much larger kit than a basic seal set: per the listing it carries Borg-Warner friction plates with matching steel plates, a Transtec soft parts set with the rubber seals and gaskets for the overhaul, a new filter, all three bands, both molded pistons and the commonly replaced bushings. Electronics are not included.
The 4T65E is a four-speed, chain-drive front-wheel-drive transaxle. Each gear is produced by applying clutch packs and bands with line pressure that the computer controls through solenoids. Over a long service life the frictions glaze and thin, steels get heat spots, bands lose lining, lip seals harden, and the molded pistons lose their seal against the drum. The result is the slow, soft shifts and flares owners notice first. Because the box includes steels, bands and pistons as well as frictions and seals, you are not left reusing the parts most likely to cause a fresh rebuild to shudder or slip.
Read codes first, then check the fluid level and condition. Clean fluid with erratic shifts usually means a solenoid, the pressure control solenoid or a valve body bore problem, and a kit will not cure that. Debris in the pan together with slipping means the clutches are finished. The Volvo unit fails in the same ways as the domestic one, so our 4T65E common problems and diagnosis guide applies directly, and the delayed engagement guide helps separate a pump or seal leak from worn clutches.
This kit is listed for Volvo 4T65E transaxles from 1999 to 2002. Confirm the identification tag on the case before ordering; our 4T65E identification guide shows where it is. Transmission Digest documents two Volvo-specific differences that matter on the bench. The valve body to spacer plate and spacer plate to channel plate gaskets are different from the domestic ones, because the Volvo circuits for forward engagement, manual first and second, and the 1-2 and 2-3 shifts are changed. The passenger-side axle seal is also different and is a dealer item. Soft parts sets are often built around the domestic gaskets, so compare the gaskets in the box with your old ones before assembly. Send us your year and VIN and we will check the application before it ships. If you have a Buick, Chevrolet or Pontiac, this is the wrong kit; browse the 4T65E parts page for domestic versions.
If you only need seals and frictions without steels, bands or pistons, the lower-cost 1999-2003 Volvo 4T65E banner kit covers the same application.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
According to the listing: Borg-Warner friction plates, steel plates, a Transtec soft parts set with the rubber seals and gaskets, a new filter, all three bands, both molded pistons and common bushings. Solenoids and other electronics are not included.
No. This kit is listed for the Volvo version of the 4T65E. Volvo units use different valve body gaskets and a different passenger axle seal, so domestic GM cars should use one of our domestic 4T65E kits.
Check before you assemble. The Volvo pair is GM 24212825 and 24212828. If the gaskets supplied match the domestic 24206578 and 24204500 instead, get the Volvo pair; using domestic gaskets can cause engagement and shift problems.
Plan on the Volvo passenger axle seal from a dealer, plus any hard parts that fail inspection, such as the input sprag, drums or a worn valve body. Fluid is extra.
Heat-marked or warped steels from the old unit can make new frictions shudder or slip. Having new steels in the kit removes that risk.
