4R70W / 4R75W Ford Transmission Case – 3 Bolt Starter (2004–2008, 4.6L / 5.4L)
This Ford 4R70W / 4R75W transmission case is designed for 2004–2008 applications equipped with 4.6L and 5.4L modular engines. Featuring the 3-bolt starter configuration, this case is commonly found in later-model Ford trucks and SUVs using the updated 4R75W platform and select late 4R70W units. The transmission case serves as the structural foundation of the transmission, housing the geartrain, pump assembly, valve body, and internal clutch components while maintaining precise alignment under load.
The 3-bolt starter design is critical for correct fitment. Earlier Ford modular applications often used a 2-bolt starter pattern, so confirming this detail before purchase prevents installation issues and bellhousing misalignment. This case supports electronic overdrive configurations and is compatible with vehicles running Ford’s 4.6L or 5.4L engines paired to the 4R70W or 4R75W automatic transmission.
Replacing a damaged or cracked transmission case restores structural integrity and ensures proper sealing between the pump, bellhousing, and tail housing. It also prevents fluid leaks, alignment problems, and internal component wear caused by case distortion.
