A mid-shift tube shaft is a mechanical component used in automotive manual transmissions. It is a shaft that connects the shift lever to the transmission gears, allowing the driver to shift between gears.

The mid-shift tube shaft is typically located in the center console of the vehicle and runs from the shift lever to the transmission. It is often connected to the transmission through a shift fork or a shift rail, which engages and disengages the gears in the transmission.

The mid-shift tube shaft may be made of steel or other durable materials, and is designed to withstand the stresses and strains of shifting gears repeatedly. It may be equipped with various features, such as a shift linkage, a shift knob, or a bushing, to ensure smooth and precise shifting.

In some cases, the mid-shift tube shaft may also be adjustable, allowing the driver to fine-tune the position of the shift lever for optimal comfort and performance. Regular maintenance, such as lubrication and inspection, may be required to ensure proper function and longevity of the mid-shift tube shaft and other transmission components.
