Review MOPAR Genuine Fourth Gear fits 2012–2019

The Mopar 68146137AA Fourth Gear is an essential component for any Dodge, Plymouth, or Chrysler transmission that requires a fourth gear replacement. This part is meticulously engineered to deliver optimal performance and durability, ensuring a seamless driving experience.

The gear teeth are manufactured using advanced heat-treated steel, which enhances their strength and resistance to wear. The surface finish undergoes a rigorous honing process to ensure precise fitment and smooth engagement with adjacent gears. This results in a quieter operation and reduced power loss within the transmission.

The fourth gear's design incorporates a robust spline shaft that securely connects it to the transmission's input shaft. The splines are precision-machined to ensure a firm connection and maintain proper gear alignment. This not only improves the overall efficiency of the transmission but also helps prevent any potential damage caused by misalignment.

The Mopar 68146137AA Fourth Gear comes with a specialized oil seal that effectively prevents transmission fluid from leaking out. This ensures the gear operates in a lubricated environment, reducing friction, and prolonging its lifespan.

Installation of this part is made easy with the inclusion of detailed instructions and clear markings on the gear. Furthermore, this Mopar original equipment manufacturer (OEM) part is designed to meet or exceed the original factory specifications, ensuring a perfect fit and reliable function.

In summary, the Mopar 68146137AA Fourth Gear is a high-quality component that provides superior performance and longevity for your transmission. It undergoes rigorous testing and manufacturing processes to ensure precise fitment, smooth engagement, and extended durability. This OEM part is an excellent choice for those seeking to restore their vehicle's original performance or address any existing transmission issues.
