The TransGo Vacuum Bypass Kit is for use on supercharged and turbocharged vehicles with transmissions that are equipped with a vacuum modulator. The bypass valve exhausts the boost pressure going to the modulator so the internal diaphragm does not get ruptured under engine boosted driving conditions. This vacuum bypass kit quickly and easily T’s into the brake booster vacuum line or directly into the intake manifold.

Corrects/Prevents Reduces:

• Prevents boost pressure from damaging vacuum modulator
• Prevents damage to transmission from incorrect pressure boost
