Why a Gearstar 4L80E?

Why a Gearstar 4L80E? A 4L80E is a four-speed overdrive transmission that is the evolutionary counterpart to the TH400 three-speed transmission.

Build both transmissions to handle 600 horsepower and Gearstar will charge you $2,200 for the TH400 and $3,900 for the 4L80E. I just added $1,700 to the drivetrain for one extra 0.75 overdrive gear.

Where is the Logic?

Where is the logic? It’s certainly not monetarily based (nor found in weight savings since the 4L80E is about 35 pounds heavier). But the superior functionality of the electronically controlled transmission with an overdrive gear cannot be argued.

While some may not prefer that the 4L80E requires a controller like HGM’s Compushift II, I like the fact that it can be easily adjusted and reprogrammed via a hand-held display. Shift pressures, shift points, torque converter lockup, and the overdrive can all be controlled via the Compushift II, giving complete control over the transmission like I’ve never had before.

The advantages and benefits of an overdrive gear that lowers engine rpm and improves fuel economy are easily apparent.
