TransGo Vacuum Modulator Kit for GM 4L60E 4L65E 4L70E 1993-2015

Upgrade your 4L60E transmission with the TransGo Vacuum Pressure Control System (46-MOD). This complete vacuum modulator kit replaces the unreliable electronic EPC solenoid with a proven vacuum-based system that delivers precise, tunable line pressure regulation directly from engine vacuum.

Key Benefits:

• More aggressive and tunable pressure boost curve for superior performance
• Eliminates common pressure rise problems that cause slipping and wear
• Ideal for high-performance, heavy-duty, and transplant applications
• Increases accumulator pressure for firmer, more positive shifts
• Includes full installation hardware and EPC resistor for trouble-free operation

Fitment: 1993-2015 GM vehicles equipped with 4L60E, 4L65E, or 4L70E automatic transmissions (except hybrids).

Installation requires the oil pan removed. The kit installs quickly with the provided components and connects to a simple intake manifold vacuum source. Full step-by-step instructions are included.
