How To Improve MPG & Performance With An Overdrive Transmission - CHP How It Works

Going Broke Filling Up Your Hot Rod? Here’s How to Improve MPG and Performance With an Overdrive TransGM automatic transmissions quite literally rule the world. The venerable Powerglide has been the gold standard of durability and efficiency in drag racing since the ’50s, and the workhorse TH400 has been factory installed in everything from big-block Chevelles to Ferraris to military-spec Hummers. In the hot rodding world, GM automatics are routinely swapped into Fords and Mopars, but you’ll hardly ever find a C6 or a TorqueFlite in a Chevy. The reason for this is two-fold. First off, GM simply builds kickass transmissions. Secondly, what GM does better than any other manufacturer on earth is stick with a small handful of trans models, keep them in production for decades, and continually enhance their durability along the way. This yields an economy of scales that drives down costs, and ensures parts compatibility for both factory and aftermarket components for decades. The only downside to this is that there are so many great transmissions to choose from that several GM transmissions will work great for any given application.

Swapping to an overdrive. I was thinking it was about how to improve an overdirve. Oh well.

GM builds very few "kickass" transmissions.. In fact it's quite the opposite..
Hot rodders build kickass trany's, GM just provides cases..
imho
