Just wondering if anyone here has some knowledge about gearbox ratios for the C 180 1994 4speed auto and C 180 1997 5speed auto. I have both cars and like to know what the ratios are in 1-2-3-4 for the first and 1-2-3-4-5 in the second. Also like to know what speeds they are in operation and change points like 0 to 20/1, 20 to 40/2 , 40 to 60/3, and 60 plus in 4th. Let me know whether in kph or mph because we only use metric here. If its 1:0.8 in 5th in the 5speed and the same in 4th in the 4speed, wouldn't it be more economical to use the 4speed transmission in town driving? I think its 1:1 in 4th for the 5speed, but 3rd in the 4 speed? Thanks buddies, UK and European members invited to reply also.
