AW5550SN

The 5-speed automatic transmission AW55-50SN was developed by Aisin specialists at the end of the last century as an exclusive 5-speed automatic transmission for non-Toyota FWD vehicles with engines from 2 up to 3 liters. After update of the valve body and computer settings, this transmission as AF23 and AF33 was installed on GM models: Daewoo-Chevrolet (Captiva, Epica, Laketti ...), Saab, Opel and American Saturn and Suzuki. The testing of this unique transmission was performed since 2000 on Volvo cars (on C70, both the 40, 70 and S60s and S80s).

Part of the design solutions for this tranmsission are adopted from its successful predecessor - the 4-speed AW50-40. The transmission was so successful that even its competitors installed AW55 for their popular cars, simultaneously releasing their RE5R05A (JR507E) (Nissan-Jatсo) and 5L40E / 5L50E (GM-Europe).
