The TH200-4R transmission is a 4-speed automatic transmission used in GM vehicles in the 1980s. The TH200-4R is often swapped in place of GM's Powerglide or TH350 as it comes with a higher torque capacity and is relatively easy to fit. Due to its great strength and durability the TH200-4R is still very popular today in racing applications and is often upgraded to handle well over its original torque rating. The Raybestos Powertrain TH200-4R transmission parts listing includes many upgraded and performance-minded friction materials to help take your next TH200-4R rebuild to another level.
