AW55-50SN Banner Rebuild Kit, new and ready to install. Fits the AW55-50SN. Ships fast from the USA.
A Volvo XC90 or S60, a Saab 9-3, a Saturn Vue or a Nissan Maxima with the Aisin five-speed that now flares on the upshifts, takes a second to grab Drive in the morning, or leaves a smear of brown clutch dust on the pan magnet is a candidate for a soft-parts rebuild. This banner kit is built for that job on the AW55-50SN and AW55-51SN, along with the AF23, AF33 and RE5F22A versions of the same transaxle. In the box you get a set of friction clutch plates, the overhaul seals and O-rings, the filter in both styles used across the family, and a front pump bushing, so the friction side of every pack and the bushing that takes the most abuse are renewed in one order.
The AW55-50SN builds its five ratios by applying multi-plate clutches and brakes, plus a band, in different combinations, with linear solenoids in the valve body setting how hard each one clamps. The friction plates are the parts that wear: every shift slips them briefly against the steels, and a pack that runs low on apply pressure overheats and glazes. A banner kit sits between a gasket-only overhaul set and a full master kit. It replaces the frictions and all of the rubber, but it keeps your steels, which saves money when the steels come out flat and clean. Because it includes both filter types and the pump bushing, it also covers the two items that most often get forgotten on a bench rebuild of this unit.
Not every harsh or slipping AW55 needs clutches. Sonnax documents linear solenoid supply problems and worn valve body bores in this family, and those faults produce soft or harsh shifts with no clutch damage at all. Drop the pan and look before you order: clean red fluid with no debris points to the valve body or solenoids, while black fluid and clutch material confirms the packs are burned. Our AW55-50SN service guide covers the checks in order, and our article on Aisin slipping under load explains how a pressure test separates a true clutch slip from a pressure problem.
This kit is listed for Volvo 2001 and later with the AW55-50SN or AW55-51SN, Saab 2002-2010 with the AW55-50SN or AW55-51SN, Nissan 2004-2007 with the RE5F22A, Saturn Ion sedan 2003-2004 with the AF23-5, Saturn Vue 2002-2003 and Saturn 2003-2004 with the AF33-5, and Suzuki models with the AF33-5. The plate count and filter shape differ between makes, which is why both filter styles are packed. Lay the new frictions next to the ones you pull and confirm the count and tooth pattern before you start stacking. If you are not sure which version is in your vehicle, send us the year and VIN first. More parts for this family are in the Aisin transmission collection.
Hard parts such as drums, the valve body and the torque converter are not included, so price those after you inspect the unit on the bench.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A banner kit carries the frictions, seals, O-rings and filter for a rebuild. A master kit adds the steel plates. If your steels come out flat with no heat marks, the banner kit is the lower-cost way to rebuild.
It is listed for the AW55-50SN and AW55-51SN in Volvo and Saab, the RE5F22A in 2004-2007 Nissan, and the AF23-5 and AF33-5 in Saturn and Suzuki models. Send us your year and VIN if you are unsure which one you have.
The filter shape varies across the makes that used this transaxle, so both styles are packed. Use the one that matches the filter you remove and set the other aside.
No. The listed contents are frictions, seals, O-rings, both filters and a front pump bushing. Steels, drums, the valve body and the torque converter are separate.
Use a fluid that meets Aisin Warner JWS 3309. Volvo, Saab and GM each sell it under their own part numbers. Then clear adaptations and let the module relearn the shifts.
