Tube Tranny -

: The tube is bolted directly to the transmission at one end and the rear axle housing at the other.

In automotive engineering, a (short for torque tube transmission) refers to a drivetrain layout where a rigid "torque tube" connects the transmission to the rear differential. This design is primarily used to eliminate wheel hop and manage the physical forces (torque) produced by the engine and drivetrain. How the System Works

: Early Fords and Buicks were famous for using "closed drive" torque tube systems before open driveshafts became the industry standard. Maintenance & Common Issues tube tranny

This setup is iconic in several specific automotive circles:

: Because the tube is rigid, it also helps locate the rear axle, often allowing for simpler rear suspension setups like those found in older Buicks or modern performance cars. Notable Vehicle Examples : The tube is bolted directly to the

If you are working on a tube tranny setup, keep these points in mind:

: When you accelerate, the rear axle tries to rotate in the opposite direction of the wheels. The torque tube resists this "twisting" force, transferring it directly to the vehicle's chassis through the transmission mounts. How the System Works : Early Fords and

Unlike a standard open driveshaft that uses universal joints to handle movement, a torque tube system houses the driveshaft inside a hollow steel tube.
