Transmission & Drivetrain

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.

Our project F-350 has 192,000 miles on the odometer now, and for the past 15,000 or so we’ve been noticing the steering and frontend getting more and more sloppy.
