WHAT THIS KIT FIXES
Over time, the factory boost valve and bore wear out, causing loss of line pressure, which leads to slipping, overheating, and premature clutch failure. The TransGo TF-BOOST kit corrects these issues by restoring proper hydraulic pressure and improving valve body performance—critical for both daily driving and heavy towing applications.

FAQ
What problem does the TF-BOOST kit fix?
It fixes low line pressure caused by a worn boost valve, which leads to slipping, poor shifts, and transmission wear.
Will this improve shift quality?
Yes. By restoring proper hydraulic pressure, shifts become firmer, quicker, and more consistent.
Is this recommended for towing?
Absolutely. Towing increases transmission load, and proper line pressure is critical to prevent clutch slip and overheating.
Do I need to remove the transmission?
No. Installation is performed through the valve body, but it does require mechanical experience.
Is this compatible with performance builds?
Yes. This is a foundational upgrade for both stock and high-performance Cummins transmission setups.
