Making the right shift at the right time is critical to getting the most performance from your transmission. The new TCI TH400 Full Manual Shift Valve Body with Low Gear Engine Braking is the best way to deliver quick shift response times and clean neutral shifting. Best of all, the full engine braking in low gear is perfect for rock crawling and 4x4 applications where utilising the engine's compression drag to help traverse the most extreme terrains is a useful feature.

The TCI TH400 Full Manual Valve Body with Low Gear Engine Braking is the perfect set-up not only for heavy off road usage, but is great for hot street/strip cars where a forward shift pattern valve body ensures reliable transmission gear selection. As with all TCI valve bodies, installation is a simple bolt-in procedure for any GM TH400 transmission with all necessary parts included and performance is guaranteed due to the orous TCI quality control standards.
