About this part

Product Details

This transmission main shaft nut is made from a strong steel alloy, just like the original factory part it replaces. It's designed to hold the main shaft securely in place within the T90 3-speed manual transmission, which is crucial for smooth gear changes and overall drivetrain integrity. If you're working on the transmission of a classic Jeep, this nut is a necessary component to get the job done right.

Omix has a reputation for making well-built parts that fit right, and this nut is no exception. It's a direct fit replacement, meaning it's made to the same specifications as the OE part, so you won't have to worry about modifications during installation. This part is commonly used when rebuilding or repairing the T90 transmission found in a wide range of Jeep models from the late 1940s through the mid-1970s, including vehicles like the CJ5, CJ6, and early Cherokee models.

When you're tackling a transmission job, having the correct hardware is key. This nut is designed to work with the main shaft washer (Omix part number 18880.12) to ensure everything stays properly tensioned and aligned. It's backed by a 5-year limited warranty, giving you peace of mind that it's built to last.
