Ford introduced the TorqShift transmission in 2003 as Dodge introduced the 48RE. Both were significant upgrades from previous transmissions used, but Chrysler's 4 speed failed to combat the reputation that the Allison 1000 had earned in the market. Ford's 5 speed TorqShift proved a worthy competitor against the heavy duty Allison, boasting a significantly higher max input rating and tighter gear ratios. Chrysler's 48RE proved to be a much more reliable gearbox than the previous 47RE, but the transmission typically lacks the longevity that the Allison and TorqShift are known for.
