Oregon Performance Transmission carries a huge selection of individual valves and springs for your automatic transmission and valve body. These valves and springs can be used to fix or correct shifting problems that your transmission might be experiencing. In many cases these issues were from poorly designed transmissions from the factory or could have occurred due to high miles. Some of these valves or springs can be installed prior to any serious damage being done to your transmission, eliminating the need for a premature, full transmission rebuild. For HD and high-performance applications, we do carry many parts to modify and upgrade your transmission to handle the additional HP and abuse. From boost valves and pressure regulators to TCC valves and springs, OPT has you covered. Browse below through our selection for nearly every make and model.
