Automatic Transmission Modulator Upgrade, 4L80E, Vacuum Pressure Control, Kit

Great for transplants! TransGo Automatic transmission modulator conversion kits provide a more aggressive and tunable pressure boost curve with engine vacuum instead of the vehicle PCM controlling PCS/EPC solenoid.

TransGo modulator conversion kits include everything needed to add the internal modulator system with the oil pan off the transmission. From the outside of the transmission, you will need to connect it to an intake manifold vacuum source, however hardware is not provided for this. The kits do come with an oil pan-based resistor to pacify the control module for the missing EPC solenoid in applications where the computer will still manage the gear changes.

TransGo includes:
• Pressure regulator valve spring and snap ring
• Brass fitting
• Vacuum modulator, pin, valve, and bushing
• Hold-down bracket
• Elbow vacuum hose and spring
• Four short zip ties
• Five long zip ties
• Vacuum tee
• Resistor
