Help your automatic transmission shift on command with the Standard Ignition Transmission Control Solenoid, part number TCS321. It is a direct-fit replacement for many vehicles, among them the 2002-2006 Nissan Altima, 2001-2006 Nissan Sentra and 2000-2006 Nissan Maxima. For the full list and engine-specific details, see the Buyer's Guide tab.
This automatic transmission control solenoid is an electrically operated valve. When the transmission control system energizes it, its pintle moves to block or vent fluid pressure in the hydraulic circuit it serves.
As a global manufacturer, Standard Ignition maintains complete quality control throughout the manufacturing process.
Signs this part may need replacing include harsh, delayed or erratic shifts, a transmission that stays in one gear, and transmission-related trouble codes. These symptoms can have other causes, so diagnose the transmission before replacing the solenoid.
