GM TH350 Transmissions & Transmission Parts

The classic TH350 powered a whole generation of GM vehicles, and if you're looking for a TH350 for your restoration project or racing build, then look no further than Tier One. We have a whole lineup of built TH350 transmissions that can handle a ton of power and aggressive applications on the street, at the track, on the drag strip, or out in the dirt. These TH350 performance transmissions offer up smooth shifting and excellent reliability, even when you're pushing your build of choice to the limit. Tier One's built TH350 transmissions are perfect for restomods, hot rods and rat rods, drag racing builds, road racing, and circle track racing.
