TF-80SC AF40 Transmission Filter & Pan Gasket Kit Volvo Ford

Aisin's six-speed front-drive automatic went into a long list of vehicles: Volvo S60, S80, V70, XC60, XC70 and XC90, Mazda CX-7 and CX-9, Land Rover LR2 and Range Rover Evoque, the Ford Fusion's Mercury Milan and Lincoln MKZ siblings, and Saab. Depending on the badge it is called TF-80SC, AF40, AF40-6, TF-81SC, AF21, AWF21 or AW6AEL. If yours has started to hesitate going into gear, slip or flare between gears, or run hot, and the fluid has never been changed, this strainer and pan gasket kit is where a proper service starts. The reference number is 60270F0990080.

What the strainer does in a TF-80SC

In this transaxle the valve body sits inside the oil pan, and the pump is driven by the torque converter hub off the crankshaft. The pump pulls fluid through the strainer and sends it to the valve body, whose solenoids are switched by the transmission control module to route pressure to each clutch and brake. The same pump also feeds lubrication and the external cooler. As the clutches wear, friction material and fine metal settle in the pan and get pulled into the strainer. Once the media loads up, the pump cannot supply full volume, line pressure sags under load, and the clutch-to-clutch shifts that this transmission depends on start to slip, flare or bang.

Symptoms a strainer and fluid service can address

• A delay before Drive or Reverse engages, worst when cold
• Flare or slip on upshifts, often felt as a rpm jump on the 2-3 shift
• A harsh or jerky shift that comes and goes with fluid temperature
• A pump whine that follows engine speed
• Fluid that is dark, smells burnt, or leaves heavy deposits on the pan magnets

These units are also known for valve body wear, solenoid faults and converter shudder, and Volvo models have a known B1 servo cover leak. A strainer will not repair any of those, but it is the first part replaced in every one of those repairs, and a clean fill makes the remaining fault easier to find.

How to confirm before you order

Start with the fluid level, which on these transmissions is not a dipstick check. Then scan the transmission module for codes and look at the fluid you drain. Clean fluid and stored solenoid or ratio codes point at the valve body; burnt fluid with friction material points at clutch wear. Our Aisin harsh and delayed shift walkthrough covers the order of tests, and the Aisin overheating guide explains why a loaded strainer and old fluid make these units run hot.

Fitment

The listing covers about 2005 to 2017 across this family, including the four-, five-, six- and eight-cylinder versions. The TF-80SC used by Volvo and Saab and the TF-81SC (AWF21) used by Ford, Mazda and Land Rover are closely related but not identical, so compare the shape and outlet of the strainer you remove against this one before you start, or send us your year, engine and VIN and we will check it. Read the transmission type from the plate on the case. More parts for these transmissions are on our Aisin transmission parts page.

Install notes

Drain the fluid and remove the pan, then unbolt the old strainer from the valve body. Clean the pan, the magnets and both sealing surfaces, coat the new strainer seal with fresh fluid and press it fully home before you bolt it down. Fit the new gasket and tighten the pan bolts evenly. Refill with the fluid specified for your vehicle: Volvo lists 1161540 and 1161640 for early TF-80SC units and 31256774 or 31256775 for later ones; on Ford, Mazda and Land Rover versions, use the fluid named in that vehicle's service information. Volvo's procedure sets the level at the level-check plug with the fluid between 50 and 60 C, read on the scan tool, adding until it just drips out. If you replace the valve body or solenoids at the same time, reset the adaptations afterward. If the drained fluid shows heavy wear, the AF40 valve body and the AF40 gasket and seal overhaul kit are the usual next parts.

Which transmissions does this strainer fit?

The Aisin six-speed family sold as TF-80SC, AF40, AF40-6, TF-81SC, AF21, AWF21 and AW6AEL, in roughly 2005-2017 Volvo, Mazda CX-7 and CX-9, Land Rover LR2 and Evoque, Mercury Milan, Lincoln MKZ and Saab models. Compare your old strainer before installing.

Is a TF-80SC the same as a TF-81SC?

They are closely related Aisin six-speeds but not identical. The TF-80SC is the Volvo and Saab version and the TF-81SC (AWF21) is the Ford, Mazda and Land Rover version. Match the strainer shape and outlet, or send your VIN.

What fluid should I use after the service?

Use the fluid specified for your vehicle. For Volvo, that is part 1161540 or 1161640 on early TF-80SC units and 31256774 or 31256775 on later ones. Do not substitute a generic ATF.

How do I check the fluid level on a Volvo TF-80SC?

With the engine running, read fluid temperature on a scan tool. When it is between 50 and 60 C, remove the level-check plug and add fluid until it just drips out, then refit the plug.

Do I need to reset adaptations after changing the strainer?

Not for a strainer and fluid service alone. If you also replace the valve body or solenoids, Volvo calls for resetting the transmission adaptations with a scan tool before the test drive.
