Re: 2000 SLK230 auto to 6 speed V8
Just that with a V-8 and the 6 speed manual I'd want something like a 2.50 rear axle.
Even with a 3.2 1st-2nd is down in the 25-30 range and can either shift real slow or have the TC go bananas. It is best to think of it as a five speed with a granny gear. It only has one OD gear.
