American Powertrain Adds GearStar Automatic Transmissions

American Powertrain has now added GearStar automatic transmissions for Ford, Chevy and Mopar to its product lineup.

American Powertrain, a leading distributor of Tremec manual transmissions, has now added to its product lineup GearStar automatic transmissions for Ford, Chevy, and Mopar. Transmissions include the 4L60E for SBC, BBC and early LT engines, the 4L65E for LS, late LT engines, SB and BB Mopar and Gen III engines, the 4L80E for LS engines, and late model LTs and the 4R70W for Ford small block engines. 

Each GearStar transmission is shipped in a protective crate with a Yank billet torque converter, transmission fluid, trans cooler and a factory-style dipstick. Each transmission option is available in various power ranges with 400-1000 ft.-lbs. of torque capacity depending on the model. American Powertrain Pro-Fit install kits are being developed for popular applications and will be announced soon. 

Matt Graves, American Powertrain Marketing and Product Manager says, “This is great news for anyone looking to put in a high-performance automatic transmission. We’ve had a lot of calls for automatic transmissions with overdrive and GearStar builds the best automatics in the industry. Just like Tremec, we are proud to offer a great transmission brand. Soon, we will be able to announce specific Pro-Fit install kits, but for now if you are looking to add a high performance automatic, our experienced team will ask all the right questions to ensure the power level you want and recommend a transmission that makes the most sense for your vehicle.”
