AWF21 Valve Body 2006-2015, remanufactured and ready to install. Fits the AWF21. Ships fast from the USA.
If you drive a 2006-2015 vehicle with the AWF21 six-speed and the transmission has started to clunk into gear, shift roughly from 5th to 4th as you coast to a light, or set ratio codes for the upper gears, this remanufactured AWF21 valve body covers the widest year span we stock for this unit. The range reaches into the final U.S. years of the TF-80SC, including the 2013-2015 Volvo XC90, so it is the listing to check first when your car is newer than 2013.
AWF21 and TF-80SC are two names for the same Aisin AW transverse automatic, first delivered in 2005, with ratios running from 4.148 in first down to 0.686 in sixth. It has no direct gear; every ratio comes from a planetary combination, and every shift hands torque from one clutch or brake to another, so timing the overlap is critical. That puts the whole job of shift quality on the hydraulics. The valve body regulates line pressure, feeds the solenoids through the solenoid modulator valve, routes apply pressure to each element and controls converter lockup. When valves and bores wear, pressure leaks between circuits and the TCM keeps adding correction until it runs out of range.
Volvo's Technical Journal 32169 applies to TF-80SC cars from 2011 through 2016 and gives the 2013-2015 XC90 its own routine. The bulletin's process is software, adaptation and diagnostics in the dealer tool, and it only counts adaptation as complete after the car has made 20 good Neutral-to-Drive shifts and 50 good 5-4 shifts. So before buying hardware, confirm the TCM software is current and that adaptation has actually been completed. If the complaint survives that, or ratio codes keep returning with clean fluid, the valve body is the likely cause. Check fluid condition at the drain: clean red fluid with codes favors the valve body, while burnt fluid full of friction material points to worn clutches. Our articles on Aisin slipping under load and reading transmission live data show what to watch on the scan tool.
This body is listed for AWF21 (TF-80SC) transaxles from 2006 to 2015. Across that span the unit was used in front-drive and all-wheel-drive models, and connector and calibration details changed along the way, so match your old body before ordering. Line up the casting, the solenoid positions and the connector with the photos, and do not substitute a Ford or Mazda TF-81SC body; it looks nearly the same but its parts are different. If you are unsure, send us the year, model and VIN and we will confirm the match. If your car is a 2006-2013 model, also compare the 2006-2013 AWF21 valve body, and see the rest of the Aisin transmission collection for pumps, kits and filters.
The swap is done in the car through the side pan. Drain the fluid, label the solenoid connectors and disconnect the manual valve link before lowering the old body. Keep the new body clean and flat, start every bolt by hand and torque them evenly in stages so the casting does not warp. Install a new filter and gasket from our TF-80SC filter and gasket kit, then refill with JWS 3309-type ATF and set the level at operating temperature. If the old fluid showed bronze or aluminum debris, inspect the pump or plan on an AWF21 overhaul kit. Last, reset adaptations and drive until the TCM has relearned, as covered in our adaptive relearn guide.

The 2013-2015 XC90 uses the TF-80SC, and this body is listed through 2015. Because calibration and connector details changed over the years, compare it to your old unit or send the VIN so we can confirm before it ships.
Volvo addressed rough 5-4 and N-D shifts on 2011-2016 TF-80SC cars with software and adaptation first. If those are current and the shift is still rough, valve body wear is the next thing to check.
Both are remanufactured AWF21 valve bodies. This one is listed for a wider range that includes 2014 and 2015 production, so it is the one to check for a newer car.
A JWS 3309-type ATF. Check the level hot at the fill plug after the swap.
Volvo's procedure counts 20 good Neutral-to-Drive engagements and 50 good 5-4 downshifts before adaptation is considered complete, so expect some mixed driving before the shifts settle.
