When folks think 6 speed transmissions in muscle cars and classics, they often think manual transmissions like the T56 or Magnum. But there are multiple 6 speed automatics as well, and they can be a huge performance upgrade from a 4 speed like a 4L65e or 4L80e. But what do the two extra gears really give you? And when does it make sense to do this kind of swap? The video below will explain the hows and whys and show you a great example of the kind of LS swapped ride that can really benefit from this one.

Video Description:

Automatic transmission technology has come a long way since 2 speeds like the famous Powerglide. Since gasoline combustion engines are emissions mandated to be run at or near the stoichiometric air-fuel ratio, the increasing number of gears are a major reason for improved fuel mileage and efficiency on the late-model cars. But what happens when your project car has its older and less advanced transmission start acting up? Is it worth the trouble and cost of swapping newer technology to reap the potential benefits? Our customer has an LS3 swapped C3 stingray and is in this exact situation so this is a perfect opportunity for us to answer these questions and maybe teach ya some stuff along the way.
