Free Wheeling: Better MPG and Less Wear with Dynatrac

We managed to get our hands on one of the first available Ram HD Transmission to the public and plan to put it to the test behind a 1,000hp 2008 Ram 2500. We’ll report back soon with how it’s holding up...

When we heard famous EFILive tuner “Idaho” Rob Coddens had a 500-rwhp, LML-powered 2013 GMC Sierra he was playing around with that still had all its emissions hardware intact, we just had to see for ourselves.

No matter how powerful your truck’s engine is, or how strong your transmission is, all that horsepower and torque goes to one place -- your rear axle.

If you drive a 1999-2010 Ford F-250, F-350, F-450 Super Duty pickup, F-550 diesel cab and chassis, diesel E-Series van, or Class C motorhome, you should know about an issue that can affect the fuel tanks.

During testing, using a 2012 Chevrolet Silverado 1500 equipped with the six-speed 6L80E, we’ve seen temperatures hit 250 degrees on multiple occasions. To fight these high temperatures, we turned to a larger transmission cooler first.

End Of Problems

There’s no debate that diesel-powered pickups are making more power than ever, and when you combine that with a big lift, it puts more strain on the rear end gears. When you put 37-inch-tall tires on a diesel truck, it’s the icing on the cake.
