First introduced in 1992 for modular 4.6 liter engines in the Crown Victoria, Grand Marquis, and Town Car models, these transmissions are excellent choices for street performance with small block engines. By 1994, these units had completely replaced the older AOD. They're readily available on the used market and are great for retrofitting into earlier vehicles.
Whether you need 4R70W wiring diagram information, 4R70W transmission rebuilders tips, 4R70W technical information, 4R70W diagnostics, 4R70W troubleshooting help, or just answers to your 4R70W transmission rebuilders question, the Transmission Rebuilders Network is the place to go! AODE/4R70W SS Mega Monster In A Box The Monster-In-A-Box transmission rebuild kit for the 4R70W, alternatively known as the AODE is available for Ford vehicles. This kit comes with all the parts you need to get your transmission up to the Monster level of performance. Converting from a 2 or 3-speed to the 4r70w Transmission may also increase the value of your vehicle because of the great performance and fuel economy. The 4R70W utilizes the Engines Throttle Postion sensor to more precisely and electronically control line pressure. Sims municipal recycling.

Important Years
4r70w Transmission Rebuild
1993
- First year of the wide ratio gear set, available only in the Lincoln MKVIII
1994
- First Windsor-style bolt pattern
1998
- Received Intermediate one-way clutch / Mechanical Diode update
- Main connector pin out was changed
- Received improved Stub Shaft
2004 Far cry 4 injector download.
- Received hardened gears in certain models, i.e. 5.4L trucks (4R75W only)
We recommend obtaining a 1998 or later transmission for your project because they contain most of the important updates and are best suited for performance applications.
Compared to the AOD, they offer increased strength, greater reliability, and complete electronic control of all transmission functions. Often times, they are a better choice and more cost effective than upgrading an AOD. Only 7/8ths of an inch (22mm) of added length to the bell housing means that these transmissions will fit just about anywhere the older AODs did.
The valve body is thicker, simpler, less likely to warp, and more reliable than that of the AOD. Other improvements include a 2 inch wide overdrive band, larger overdrive servo, stronger input shaft, and lockup converter clutch rather than mechanical, gear-dependent lockup.
The torque converter clutch can be locked or unlocked in 2nd, 3rd, and 4th gear. This means you don't have to compromise between streetability and performance. Although unable to in its factory configuration, it is possible to modify the valve body to achieve converter clutch lockup in 1st gear. 4R70W (wide gear ratio) offers all of the above with lower 1st and 2nd gear to aid acceleration.

Synchronous vs. Non-Synchronous Shifts
4r70w Transmission For Sale
A synchronous shift is one that requires either a clutch or a band to release before the next element engages to complete a shift. These can take longer to complete and be more difficult to tune. Non-synchronous shifts occur by simply applying the next element and do not require any components to release prior to engaging the next gear. Another advantage to using the AODE / 4R70W platform is the fact that they are non-synchronous during the 1-2 and 2-3 shifts.
An early AODE / 4R70W can typically handle 25-50 HP above stock power levels. Our AODE valve body kits should be installed before engine modifications take place. 1998 and later 4R70Ws can handle up to 500 HP with our valve body kit. 2001 and later can handle 500hp with only our controller or modified engine computer. Higher power levels should consider having the transmission rebuilt with heavy duty components from a reputable transmission shop.
