AF40 Solenoid Kit 2006-2014, new and ready to install. Fits the AF40. Ships fast from the USA.
A 2006-2014 Volvo S60, V70, S80, XC70 or XC90, or a Saab 9-3 or 9-5, with the six-speed automatic that bangs into Drive, slams a 5-4 coasting downshift, flares between gears or shudders at cruise is a prime candidate for tired solenoids. AF40 is the name GM, Opel and Saab used for the Aisin TF-80SC that Volvo fitted to most of its five-, six- and eight-cylinder cars. This is a complete new set of all eight valve body solenoids for that 2006-2014 window, so you replace every electrical control in one job instead of guessing which one is weak.
The TF-80SC is a clutch-to-clutch six-speed: one clutch must release at exactly the moment the next one applies, and the solenoids are what time that handoff. Volvo's own technical newsletter describes eight solenoids on the valve body: six that manage the shift process, one that controls torque converter lock-up, and one that sets system (line) pressure. The transmission control module bolts to the top of the case and fires them directly. In this kit you can see that split in the parts: six long linear pressure-control solenoids with colored connectors and two short tabbed on/off solenoids. TransGo's repair notes for this unit identify the valve body positions as SLC1, SLC2, SLC3, SLB1, the lock-up solenoid, SLT and the S1 and S2 shift solenoids.
Read codes with a scan tool that talks to the transmission module, and check whether a software update or adaptation is outstanding; Volvo Technical Journal 32169 handles rough N-D and 5-4 complaints on the TF-80SC with an updated adaptation routine before parts are replaced. If the complaint survives fresh adaptation and a correct fluid level, test the solenoids. TransGo specifies 5 to 7 ohms across the connector pins of a linear solenoid, and an open circuit from either pin to the solenoid body; one that fails either check needs replacing. Our Aisin harsh or delayed shifts walkthrough covers the wider diagnostic path, including the TF-80SC.
This listing is for the AF40 in 2006-2014 applications. TransGo's coverage for the same valve body includes the Volvo S60 and V70 2006-2010, S80 and S90 2007-2010, XC90 2006-2010, XC70 2009-2010, XC60 2009 and C30 and C70 2010, plus the Saab 9-3 2006-2010 and 9-5 2010. Aisin built this transaxle for many brands and revised the valve body over the years, and the closely related TF-81SC uses a similar but different layout, so compare the connector colors and shapes on your old solenoids with the photos, or send us your year, model and VIN before ordering. The rest of the family is in our Aisin transmission parts collection.
The valve body lives under the pan. Drain the fluid, remove the pan and valve body, and mark every solenoid to its bore before removing it; TransGo is blunt that positions must not be swapped. Install new O-rings lubricated with fresh fluid and seat each solenoid fully before the retainers go back on. Refill with the fluid specified for your vehicle and set the level hot: Volvo checks it at 50 to 60 degrees C with fluid just dripping from the level plug. Then reset the transmission adaptations with a capable scan tool and drive the car through enough shifts to relearn. If the valve body bores are worn, solenoids alone will not cure the shift quality, and a remanufactured TF-80SC / AF40 valve body assembly is the better fix; for a full rebuild, pair this kit with the TF-80SC master rebuild kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. AF40 is the GM, Opel and Saab name for the Aisin TF-80SC six-speed; Volvo calls it the TF-80SC. Ford and Mazda used the related TF-81SC, which shares parts but not every valve body detail.
All eight: six linear solenoids for shift, lock-up and line pressure control, plus two on/off shift solenoids, which matches the eight-solenoid layout Volvo describes for the TF-80SC.
Because the six linear solenoids work together on every clutch-to-clutch shift and wear at a similar rate, replacing the whole set with the valve body out avoids a second teardown. Keep each one in its original position.
TransGo specifies 5 to 7 ohms between the connector pins and an open circuit from either pin to the solenoid body. A solenoid that fails either test should be replaced.
Yes. Reset the transmission adaptation with a scan tool after the job and after any fluid service, then drive through repeated shifts so the module relearns clutch fill times.
