Precision Performance Products recently contacted us that they re-engineered the Lever and Cable Bracket for GM TH350 transmissions. They found that the geometry for common TH350 cable bracket and lever combinations were off just enough to cause problems on certain aftermarket transmission valve body applications. When they looked closer, they found that the geometry for these components was also incorrect for common TH350 applications using standard valve bodies. What this means is that the typical TH350 cable bracket and lever components we've used for decades (no matter the shifter brand) were not accurate!
The re-engineered components are now available on our website, and we're the first to offer these new products! (see image comparisons below)
Part #PPP-620 (620a) GM TH350 Cable Bracket and Lever Kit
Part #PPP-621 (621a) GM TH350 Lever
Part #PPP-615 (615a) GM TH350 Cable Bracket
WARNING: Do not mix-and-match the individual components. If you only need the lever or bracket, you MUST still purchase the corresponding bracket or lever. These items are not compatible individually with any other brand product. Example: The PPP-618 Lever is not compatible with a B&M, Hurst, Turbo Action (or other brand) cable bracket. If unsure what you have, please order kit Part #PPP-619 that includes both components or create a support ticket for assistance.
The benefit to these re-engineered products is improved shifting accuracy and adjustment.
NOTE: Our customers receive the re-engineered products on any new orders. We've already stopped offering the older design. The new designs have an "a" on the stamping.
