The Ford 5R55S transmission was built first in 2002. It was designed for two-wheel drive and four-wheel drive automobiles. Models like Jaguar, Mustang and Explorer have used this gearbox. One important fact is that there are several variations of the 5R series. To avoid confusion, a used 5R55S transmission for sale can be ordered here. Other units are in stock should someone require these too.

The Ford 5R55S automatic transmission has special modes for operation. Just like a manual gearbox, the SelectShift provides similar control without the need for a clutch. Some automobiles provide an automatic override system. The first gear ratio is 3.22. The reverse is 3.07. A complete range is provide in between these settings.
A stock torque converter is included with all variants. This provides the power to the assembly. Because the 5-speed is electronically controlled, there are solenoid packs in use. Drivers have the ability to dial in whatever torque is needed based on these digital controls.
Reasons People Swap 5R55S Gearboxes
Most Ford Motor Company products are sold with an extended warranty option. While some auto owners buy extra coverage, many do not. There are no guarantees with OEM parts. A failure can happen due to electrical problems, age or excessive abuse. There have been common issues reported publicly with SelectShift transmissions.
Most people seek a replacement assembly because of the following problems:
