New TH400 Valve Body Recalibration Kit
This kit is designed for the big power automatic shift combos. It not only improves the shifts, it makes several circuit changes that allow the transmission to live in an environment where most builders would recommend a full manual VB. Allows manual/automatic shifting, more direct clutch apply area, firmer shifts, eliminates 3rd gear pressure drop, intermediate clutch failure in big power combos, and excessive reverse pressure.
Intended for use during rebuild to save the builder time and provide greater quality to your rebuild. No need to clean/modify the stock plates.
TH400 Automatic Shift "Cheater" Transbrake
All new design transbrake that is activated by the shifter position. Great for use in a street/strip combo or where an electrically operated transbrake isn't allowed.
Allows normal automatic features when operated in the Drive position. Quick release design with additional features built in for bigger power cars.

Griner CNC'd Billet TH400 Transbrake valve bodies.
Several options available from the standard G10 Pro-Tree design up to the spragless G25.
G10 is the valve body many have been judged by.
It features super fast release, lighter weight than stock, clean sheet design.
Call for pricing and availability.
G15 is the clean neutral version of the G10. It allows shifting to neutral safely at the end of a pass to reduce load on aluminum rods or high rpm combos.
The G20XST or XAL is a spragless design. It eliminates the weakest part of a TH400 and makes it bulletproof at elevated power levels.

G25 is the spragless safe neutral design.
$1350 for iron drum version, $1750 for aluminum drum version.
