FMX 67-73 Gearbox Tuning Kit
This allows you to convert the factory automatic transmission to manual shifting (i.e., changing gears manually), providing sharper, more responsive 1st-2nd and 2nd-3rd gear shifts—ideal for high-torque engines or tuned cars. The kit includes a new "compensator valve," which eliminates the problem of delayed pressure buildup, resulting in faster and more reliable gear changes. This is a great solution for those who want sharper transmission characteristics while still being able to revert to the standard automatic with minimal intervention.
