Reducing valve bore within a transmission valve body can wear out over time, causing hard shifting, fault codes, and solenoid failures. TransGo reducing regulator reamer and guide tools provide an inexpensive solution for repairing regulator valve bores to eliminate further issues. These reamer tools are made from high-quality steel to ensure durability when drilling and are the same type of tool that can be found within the TransGo shift kits.
