When it comes to heavy-duty trucks, the Ford F-350 stands out as a true workhorse. At the heart of this powerful machine lies its robust transmission system. The Ford F-350 Super Duty has used six different transmissions across its 35 plus year production history, and choosing the right replacement depends on your year, engine, and trim level. This page is your complete guide to the Ford F-350 transmission family, including the E4OD, 4R100, 5R110W TorqShift, 6R140 TorqShift, and 10R140 automatic transmissions, plus the ZF S6-650 6-speed manual transmission offered from 1999 through 2010.
The F-350 Super Duty transmission lineage tells the story of Ford's evolution in heavy-duty truck engineering. Each transmission represents a generational improvement in capacity, fuel economy, shift quality, and integration with the engine.
The E4OD (Electronically-controlled 4-speed Overdrive) was Ford's first electronic heavy-duty automatic transmission. Based on the legendary C6 3-speed automatic that preceded it, the E4OD added overdrive and electronic control:
The 4R100 was the upgraded successor to the E4OD with strengthened internals and revised programming for the 7.3 Powerstroke HPCR:
The 5R110W introduced the TorqShift branding and a 5th gear for the Super Duty platform:
The 6R140 was a clean-sheet design introduced alongside Ford's in-house 6.7L Powerstroke:
The 10R140 is the most recent Ford F-350 transmission, introduced for 2020:
For owners preferring manual transmission, the ZF S6-650 (commonly "ZF6") was offered from 1999 through 2010. Designed by ZF Friedrichshafen of Germany:
This specific listing covers the ZF S6-650 6-speed manual. Note: the live page on the source site labels this transmission "S6-750," but there is no ZF S6-750 transmission. The 750 in "S6-750" appears to be the torque rating (750 lb-ft) confused as a model number. The actual ZF designation is ZF S6-650, with HD variants rated up to 750 lb-ft.
Match your truck year and engine to identify the correct transmission:
A common point of confusion: Ford F-350 transmissions do NOT factory-fit GM (Silverado/Sierra) or Dodge/Ram HD trucks. Three different brands use three completely different transmission families:
A Ford F-350 transmission will NOT bolt to a Chevy or Ram engine without major modifications.
Opting for a used Ford F-350 transmission can be a cost-effective solution without compromising on quality. Benefits:
