Chevy Silverado Gear Ratio Chart: Explore Different Gear Ratios Of Various Trucks

All Chevrolet Silverado models, including 1500, 2500, 3500 & HD truck series manufactured in different years, came with other transmissions, yet some vehicles boasted identical transmissions.

Consequently, those trucks featured the same gear ratio. For instance, Chevy Silverado 1500 & 2500 trucks produced between 1999 and 2006 come with 4L60-E 4-speed automatic transmission, and thus all these light-duty vehicles have the same gear ratio of 3.05, 1.625, 1.000, 0.696 & 2.29.

Again, this gear ratio matches with another transmission titled Hydra-Matic 4L65-E 4-speed automatic, found in a 2003 Chevy Silverado SS. The only difference between these transmission gear ratios is that the 4L65-E lacks the reverse gear.

Likewise, the Allison 1000 5-speed auto and Allison 1000 6-speed automatic transmission found on 2006 & 2018 Chevy Silverado 2500HD & 3500HD trucks have the same gear ratio of 3.094, 1.809, 1.406, 1.00, 0.711, & R-4.48.

The subtle difference between these two transmission gear ratios is that the 6-speed one features an additional 6th gear whose ratio is 0.614. So, these are the common gear ratios found in different transmissions used in Chevy Silverado trucks.

Now, let’s discuss which Chevrolet Silverado models have the same gear ratio regardless of production year and generation. The Chevy Silverado 1500 models featuring 4L80-E transmission produced between 1999 and 2014 have identical transmissions with exact gear ratios.

The Chevrolet Silverado 1500 & 2500 LD with NV3500 5-speed manual transmission comes with the same gear ratio, and Silverado 2500HD & 3500 with NV4500 5-speed manual transmission also get the exact gear ratio.
