What Makes For a Good Hot Rod Overdrive And How To Install One - Rod Authority
Rod Authority spoke with Patrick, a Master Builder for Gearstar, talking about what to look for in a performance overdrive. “Each Gearstar transmission is fully remanufactured by one Master Tech Builder,” he told us. “From tear down to prep and even selecting the parts that go in each Gearstar transmission.”
In order to get quality and performance out of the transmission, you need quality parts. Gearstar uses only the best for their transmissions.“We use Koline steels, Torrington bearings, Raybesos Stage1 clutches and Sonnax hydraulics to ensure the customer ends up with a transmission that will last and perform” Patrick said.
Gearstar performance transmissions are classified in level’s. Level 1 is basically stock, Level 2 is typically good to about 450 hp, depending on the transmission itself. Gearstar’s Level 3 builds are a good choice for the mid-level power range. A Level 4 4L65E is good to 650 hp, while the same level Ford 4R70W is only good to 450 hp.
