I discovered something interesting when I was researching what my transmission gear ratios where. the normaly aspirated Crossfire and SLK320 the same fifth gear ratio as the V8 MB ratios but all the other gears are slightly lower than the V8 ratios. The SRT/SLK32 uses the V8 ratios. I think I want to start out with the V6 ratios as that will help acceleration since I also have 3.27 final drive and most of the V8' and SRT' have 3.07


I was checking into this because you have to know all the ratios when programming the car.
