TH350 Transmission

The GM TH350 is a versatile and strong 3-speed longitudinal automatic transmission that was developed in 1969. The TH350 or Turbo 350 was paired with V6 & V8 small block engines and used in a large variety of rear-wheel drive vehicles. The Raybestos Powertrain TH400 transmission parts listing includes many upgraded and performance-minded friction materials to help take your next TH400 rebuild to another level. See more product details below.
