TF-81SC Master Rebuild Kit, new and ready to install. Fits the TF-81SC. Ships fast from the USA.
A TF-81SC that slips in 4th, 5th or 6th, flares on the 3-4, or drops into failsafe with ratio codes has usually cooked a clutch pack. Once the pan shows lining material, the only real fix is to take the unit apart. This is a master rebuild kit for the Aisin TF-81SC six-speed (also called the AF21), built as kit T19700A: the overhaul gasket and seal set (T19702A), plus a friction set and a steel set. It is aimed at the Volvo, Saab, Opel, Peugeot, Citroen and Alfa Romeo cars that used this transaxle.
The TF-81SC is a transverse six-speed with three planetary sets, three clutches (C1, C2 and C3) and two brakes, controlled by linear solenoids in the valve body. Each upshift is a clutch-to-clutch handoff timed by the TCM, so a pack that has lost lining or a piston seal that leaks shows up as flare, slip or a harsh shift long before the car stops moving. This kit replaces all of the wear items in one go. The photo shows a full set of lined frictions, a full set of steels, the pan gasket, the valve body separator plate gaskets, front and axle seals, the case O-rings and piston seals, and the accumulator rubbers.
Not every TF-81SC complaint is a clutch failure. Solenoid modulator bore wear in the valve body causes low solenoid feed pressure and the same ratio codes, and a sticking clutch control valve can flare a shift with healthy frictions. Read live data for commanded versus actual gear, check the fluid for lining material, and test the solenoids before you commit. Our Aisin harsh or delayed shift walkthrough covers the order of checks, and the solenoid multimeter test rules out an electrical fault in a few minutes.
The kit is listed for the TF-80SC and TF-81SC family. Applications named on the listing include the Volvo S60/R 2005-07, V70R 2006-08, S80 2006-09, XC70, XC90 and XC60, Saab 9-3 2006-09, Opel Vectra, Signum, Astra, Zafira and Insignia, Cadillac BLS 2006-09, Peugeot 307, 407, 607 and 807, Citroen C5, Renault Espace and Vel Satis, Alfa Romeo 159, Brera and Spider, and the 2008-09 Jaguar X-Type. Fitment is a guide only, because the TF-80SC and TF-81SC look nearly identical and some internal parts differ between them. Read the tag on the case, or send us the year and VIN and we will confirm it. All parts for this family are in the Aisin transmission collection.
Soak every friction in fresh JWS 3309 fluid before assembly and measure each pack's clearance as you build it. Air-check each clutch circuit before the valve body goes back on. While the case is open, inspect the valve body for solenoid modulator and clutch control bore wear; a worn body will flare a fresh build, so a replacement TF-81SC valve body is worth pricing now. Finish with a new filter and pan gasket kit, fill with Mobil 3309 ATF, set the level hot, then clear the adaptive values and drive the car through several full shift cycles.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It combines the T19702A overhaul gasket and seal set with a full friction set and a full steel set: pan and valve body gaskets, front and axle seals, O-rings, piston seals and accumulator rubbers.
They are close relatives and this kit is listed for both, but they are not fully interchangeable inside; even the manual valves differ slightly. Read the tag on the case or send us your VIN before ordering.
It uses a JWS 3309 type fluid such as Mobil 3309. Set the level hot after the rebuild.
Not always. Those codes are often caused by a worn solenoid modulator valve bore in the valve body. Check the fluid for lining material and test the solenoids first. If the clutches are burnt, rebuild with this kit and address the valve body at the same time.
Yes. Clear the adaptive values with a capable scan tool and drive the car through repeated upshifts and downshifts so the TCM can relearn clutch fill times.
