Too much line pressure can cause damage to various parts under the hood of your vehicle. TransGo vacuum bypass kits will run vacuum to the transmission, even set to full manual. Not doing so will put excessive strain on your pump, seals, and engine thrust bearing. Bypass units are for use on engines with a vacuum modulator that are supercharged or turbocharged—to prevent increased boost from causing runaway line pressure.

RevMax's billet modified high-pressure pumps have been upgraded and modified to be able to produce over 325 psi with proper tuning. However, you would need a RevMax 68RFE valve body to be able to achieve more than 175 psi because of factory restrictions. All 68RFE pumps have been reworked with new valving and springs, and have passed multiple vacuum and pressure tests to ensure proper operation and reliability for many years. Select the RevMax modified high-pressure billet pump designed for your transmission. Note: Even though RevMax's pump can achieve extremely high pressure, it does not mean that they recommend more than 225 psi in the 68RFE transmissions.
