AF40 Master Rebuild Kit, new and ready to install. Fits the AF40. Ships fast from the USA.
AF40 is the name GM, Saab and Opel used for the Aisin TF-80SC and TF-81SC six-speed, and it is the code you will find in Cadillac BLS, Saab 9-3 and Opel Insignia, Vectra and Zafira paperwork. When one of these starts slipping on the 2-3 or 4-5, engages late into Drive, or burns its fluid dark in a few thousand miles, the clutch packs are finished. This master kit, built as kit T19700A, gives you everything to overhaul it: the T19702A gasket and seal set plus a full friction set and a full steel set.
Inside the AF40 are three planetary sets controlled by three clutches and two brakes, all applied by linear solenoids through the valve body. There is no band to adjust and no shift kit that can make up for glazed lining. Each shift is one clutch releasing while another applies, so the friction surfaces and the piston seals have to be right for the TCM's timing to work. This kit replaces the parts that wear out: every friction and steel, the pan gasket, the valve body separator gaskets, the pump and axle seals, the piston seals and O-rings, and the accumulator rubbers shown in the photo.
Pull the pan first. Clean fluid with a quiet shift complaint usually points to the valve body or a solenoid, not the clutches. A worn solenoid modulator bore causes low solenoid feed pressure and the P0729, P0734 and P0735 family of codes on this unit even when the frictions are healthy. If the pan holds lining material and the slip shows in live data as a ratio error under load, the unit needs a teardown. See our Aisin slipping under load guide for the checks, and Aisin overheating prevention for keeping the new build cool once it is back in.
The kit is listed for TF-80SC, TF-81SC and AF40 units. Applications named on the listing include the Opel Astra 2006-09, Insignia 2008-09, Signum 2005-08, Vectra 2005-09 and Zafira 2006-09, the Cadillac BLS 2006-09 and SRX 2009, the Saab 9-3 2006-09, Volvo S60, V70, XC70, S80, XC90 and XC60, Peugeot, Citroen, Renault, Lancia and Alfa Romeo models and the 2008-09 Jaguar X-Type. Treat that list as a guide. The TF-80SC and TF-81SC versions differ inside, so match the tag on your case, or send us the year and VIN before ordering. Browse the rest of this family in the Aisin transmission collection.
Strip the case, clean and air-check each drum, and soak all frictions in JWS 3309 type fluid before you build the packs. Measure clearance on every clutch and brake pack as it goes together rather than assuming the new lining stacks to the same height. Check the pump for scoring and bushing wear; if it is marked, pair the kit with an AF40 pump. Look at the valve body as well, because a worn modulator or clutch control bore will flare a fresh build; the AF40 valve body is the fix if it is worn. Fill hot to the check plug, clear the adaptive values and drive several full shift cycles before you judge shift quality.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. AF40 is the GM, Saab and Opel name for the Aisin TF-80SC and TF-81SC family. This kit is listed for all three names, but match the tag on your case because the two Aisin versions differ inside.
The T19702A overhaul set (pan and valve body gaskets, seals, O-rings, piston seals and accumulator rubbers) plus a complete friction set and a complete steel set.
The listing describes it as overhaul, friction and steel kits only. Plan on a separate filter and pan gasket kit for the final service.
A JWS 3309 type ATF. Fill hot to the check plug, not cold.
Not always. A worn solenoid modulator bore in the valve body causes that code too. Check the pan for lining material first. If it is clean, look at the valve body before you rebuild.
