All 63 AMGs use the new 7 speed tranny....Originally posted by BBGT2
AFAIK all AMG cars use the 5speed due to torque handling issues, dont know about the new AMG63 series though. The early ones though had to use the AMG tuned 5 speed gearbox, whereas all the other Non-AMG cars had the 7speed slushbox starting in 2005 I think.
