AF40 Overhaul Kit 2006, new and ready to install. Fits the AF40. Ships fast from the USA.
A Saab 9-3, Cadillac BLS, Opel or Volvo with the Aisin six-speed front-drive automatic that drips fluid at the axle seals, takes a beat to engage after a cold start, or flares between gears once it is hot is often losing pressure through hardened rubber rather than burnt clutches. This listing is a new TransTec overhaul kit for the AF40, the GM and Saab name for the Aisin TF-80SC, marked for 2006-up units and carried under reference DP2512. It contains the gaskets and seals that reseal the whole transmission during a teardown.
Inside the AF40 are three planetary sets, three clutches and two brakes, with no band and no shift that relies on a one-way part alone. Every gear change is one element releasing while the next applies, and the valve body's linear solenoids meter pressure to those pistons in fractions of a second. That only works if each piston seal and each rotating sealing ring holds what the solenoid commands. When rubber hardens with heat and age, pressure leaks away during the fill, the apply comes late, and the control unit compensates until it can no longer hide a flare. The overhaul kit renews that sealing layer: the pan gasket, valve body separator and cover gaskets, front pump seal, drive axle seals, piston seals, sealing rings and the many O-rings that sit between the case, pump and valve body. The photo shows the gasket sheets, lip seals and O-ring set; frictions, steels and a filter are not part of this kit.
Start at the pan. Clean fluid with a quiet shift fault points to sealing or the valve body; dark fluid full of lining means the clutches are gone and you need an AF40 master rebuild kit with frictions and steels instead of a reseal alone. Sonnax documents a wear point in the solenoid modulator bore of this family that drops feed pressure and sets the same ratio codes, so rule the valve body in or out before blaming seals. Our Aisin harsh or delayed shifts walkthrough and Aisin slipping under load guide lay out the scan tool and pressure checks in order.
The kit is listed for 2006-up AF40 / TF-80SC six-speed units. That family went into the 2006-on Saab 9-3, Cadillac BLS, several Opel models and Volvo cars and SUVs, but the TF-81SC used in Ford and Mazda products is a different seal and gasket list and is not covered here. Early 2005 units and late revisions may use different pieces, so compare the tag on the case with the listing, or send us the year and VIN before ordering. If your build date is earlier, see the AF40 overhaul kit for 2005-12, and browse every related part in the Aisin transmission collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. AF40 is the name GM, Saab and Opel used for the Aisin TF-80SC six-speed front-drive automatic. Volvo calls it the AM6. The TF-81SC in Ford and Mazda models is a related but different unit.
Gaskets and seals for a complete reseal: pan and valve body gaskets, pump and axle seals, piston seals, sealing rings and O-rings. It does not include frictions, steels, a filter or hard parts.
It includes new drive axle seals, so yes if the leak is the seal itself. Inspect the axle surface the seal rides on and the case bore; a grooved shaft or scored bore will keep leaking.
This family uses JWS 3309 type fluid. Use the same fluid to pre-soak seals during assembly and to fill the unit, then check the level hot by the factory procedure.
Yes. Clear the adaptive values with a scan tool after the work, then drive through every gear with light and moderate throttle so the control unit can relearn clutch fill times on the new seals.
