I don't think the auto has a 3.73.

No 3.73

3.91, 3.63, 3.29, 3.05, 3.69, and 3.42 are all of the available ratios used in the 4T40 (and 4T45) transmission; Made possible by using combinations selected from 3 different sprocket combinations (32/38, 35/35, 33/37) and 2 differentials (3.29, 3.05).




On the inside my car looks like a fighter jet.
