**Unlock Smooth and Reliable Gear Shifting for Your Nissan Altima**

Is your Nissan Altima experiencing erratic gear shifts, warning lights on the dashboard, or even failure to shift out of park? The culprit is often the central brain controlling these functions: the Transmission Control Module (TCM), also known as the Shift Lock Computer, Gear Position Controller, or Gear Control Unit. Sourcing a reliable, direct-fit replacement is crucial for restoring your vehicle’s performance and safety. Our premium used OEM Transmission Control Module, identified by part numbers **28540-9Y000**, is the definitive solution engineered specifically for your Altima.

This module is not a generic aftermarket part; it is a genuine OEM unit sourced from low-mileage vehicles. It is designed and calibrated by Nissan to work in perfect harmony with your Altima’s engine control unit (ECU) and transmission system. The part number **28540-9Y000** guarantees a perfect plug-and-play installation, ensuring all electrical connectors and mounting points align seamlessly with your vehicle’s setup. This module is responsible for precisely processing data from various sensors to control shift points, torque converter lockup, and the shift lock solenoid, which is essential for releasing the shifter from the ‘Park’ position.

Why choose this used OEM module over other options? The answer lies in quality, compatibility, and value. While new OEM modules from dealerships are prohibitively expensive, and cheap aftermarket clones can lead to compatibility issues and premature failure, a used OEM part offers the perfect balance. You get the original Nissan engineering, built with high-quality components, at a fraction of the cost. This unit has been rigorously tested to ensure it delivers the same flawless performance as the day it was first installed.

Common symptoms indicating a failing TCM include:
* Inability to shift out of Park.
* Harsh, delayed, or slipping gear changes.
* The vehicle getting stuck in a single gear (often “limp mode”).
* Illuminated Check Engine Light with transmission-related diagnostic trouble codes (DTCs).
* Unresponsive or erratic shifter behavior.

Compatibility is key. This TCM, part number **28540-9Y000**, is verified to be compatible with various model years of the Nissan Altima, particularly those equipped with the CVT or conventional automatic transmissions. It is imperative to cross-reference your vehicle’s VIN and the original part number to ensure a perfect match.

Invest in the longevity and smooth operation of your Altima. By installing this guaranteed-used OEM Transmission Control Module, you are choosing a proven, reliable, and cost-effective repair. Restore the intelligent shifting and driving confidence you expect from your Nissan.
