Restore precise shift timing and eliminate erratic performance in your 4L80E with this high-quality manifold pressure switch from Stellar Automotive Group.

This direct-replacement MAP (Manifold Absolute Pressure) sensor/switch monitors engine vacuum/load to control line pressure and shift points.

• Cadillac Escalade
