We've upgraded transmission technology in the new SLK-Class and included innovative new options. The result is our most crisp and direct changing ever.

The SLK 200 KOMPRESSOR comes with a 5-speed automatic transmission, while the SLK 300, SLK 350 and the SLK 55 AMG feature the 7G-Tronic automatic transmission as standard.  The world's first seven-speed automatic gearbox.
