7 speed Auto Trans Ratios

Gayle280 · 05-10-2008

I'm wondering if anyone has the gear ratios for the 7 speed auto. I found the 6 speed manual,but can't find anything on the auto. Also are they the same for the 280/350.

Here are the ratio's for the SLK55, not sure if they're the same for the 280/350, but I suspect they are. The rear drive ratio is different though (3.06 for the SLK55).

1. 4.38
2. 2.86
3. 1.92
4. 1.37
5. 1.00
6. 0.82
7. 0.73

The gear ratios are all the same for the 7 speed auto transmission.
But the 3.06 is the axle drive ratio of the 55AMG, the 280 and 350 have 3.27.
