Complete gearbox
A complete gearbox is the best solution for vehicles with major transmission failure or wear. Delivered fully assembled, tested and ready to install.
The complete gearbox is ideal when a transmission is too damaged or worn to be rebuilt part by part. Instead of replacing individual components, a full replacement unit is installed — offering a reliable and time-saving solution that restores full drivetrain performance.
At Sanders Parts, we supply complete gearboxes for manual and automatic transmissions in trucks, vans and specialty vehicles. Each unit is thoroughly tested for pressure, sealing, internal function and gear timing. Whether new or professionally remanufactured, our gearboxes are ready for direct installation and long-term operation.
We also offer exchange systems where available — allowing customers to return the old unit for a faster and more affordable replacement. This minimizes downtime and simplifies logistics.
