The AOD (for automatic overdrive) was a four-speed automatic transmission with overdrive. Introduced in 1980, it was Ford's first four-speed automatic overdrive transmission. The design is based on the same gearset as the Ford FMX transmission of the 1960s and 1970s. The AOD replaced the majority of Ford's older transmissions, including the Cruise-O-Matic and C5.
Applications:
The Ford AOD-E and 4R70W Transmissions. 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. The AOD takes a 164-tooth AOD-specific flexplate instead of the smaller 157-tooth pieces common to the C4 and early Ford manual transmissions. Because the AOD is longer, the crossmember must position the mount farther to the rear of the vehicle to support the transmission.

- The AOD was used originally on '80s and early-'90s Ford, Lincoln, and Mercury products and in the F-series pickups and E-series vans as well. Because Ford used these transmissions in so many production vehicles, the Ford AOD is relatively easy to locate at used parts yards and can be purchased for a reasonable price.

AODE
The AOD was redesigned with electronic controls in 1991, becoming the AODE. It was mainly intended for the new ModularV8 at first, but it was also adapted to the old AOD bell-housing for vehicles still powered by OHV engines. While the AOD and AODE/4r70w share some basic components like oil pans, gear sets (AODs and AODE can be retrofit with 4r70w gear sets), most of the internals are not interchangeable. The transmissions are not interchangeable either, as the AOD only uses a throttle valve cable for operation. The AODE and 4r70w are controlled by the Powertrain Control Module (PCM) also sometimes referred to as the Electronic Engine Control (EEC).

Applications:
- 1991–1994 Lincoln Town Car
- 1993–1994 Ford Crown Victoria
- 1993–1994 Mercury Grand Marquis
- 1994–1995 Ford Mustang
4R70W
A revised version of the AODE was released in 1993 with the Lincoln Mark VIII. 4R70W stands for 4 gears, Rearwheeldrive, 70 number assigned by Ford which represents the input torque in Lb-Ft for which the transmission was designed times 10 (70 x 10 = 700 Lb-Ft) and Wide gear ratio. It has lower 1st and 2nd gear ratios for better take-off acceleration and improved gearset strength. On vehicles powered by a 5.4 L V8, a stronger gearset is used than in normal duty 4R70Ws. In 1998, due to durability concerns, the intermediate one-way roller clutch was replaced with a mechanical diode providing extra holding capacity and longer service.
The gear ratios are:1st: 2.84 :12nd: 1.55 :13rd: 1.00 :14th: 0.70 :1Rev: 2.23 :1
Applications:
- 1993–1998 Lincoln Mark VIII
- 1993–2003 Ford F-Series
- 1994–1997 Ford Thunderbird
- 1995–1998 Lincoln Mark VIII

Many improvements have been made to the 4R70W since 1993, the most significant was the use of a 'Mechanical Diode' beginning with the 1998 models. Newer transmissions are referred to as 4R70E, 4R75W or 4R75E to differentiate them from previous models. The 4R75E/W has greater torque capacity (75 x 10 = 750 Lb-Ft) than previous models.
The most practical modification for the 4R70W is the J-mod. It involves modifying the valve body gaskets and changing some accumulator springs to alter the shift timing of the transmission. It encompasses modifications specified by one of the Ford engineers that designed the transmission. Edge is not opening pdf files. It offers quicker shifting, smoother operation, and increased service life. All parts can be bought at Ford dealers for less than $60 including the fluid.
A 20,000+ GVW cooler is highly recommended for all vehicles. Breakdown of the transmission fluid often results in 'converter shudder' (feels like driving over rumble strips) where converter tries to maintain a steady slip rate during lock-up, but alternates between slipping and grabbing. Frequent fluid changes, especially when used for towing, are the single best method to prevent shudder. Shudder occurs because the torque converter never fully enters 'lock-up', but is designed to slip slightly during steady-state operation. The reason Ford decided to use 'Steady-state-slip' is often discussed but no complete answer has been found.

Four-speed AOD transmissions come in four different types, each of which takes an extraordinary form. This transmission cannot be used with Ford engines. Transmission in the vehicle cannot be read. This transmission is almost identical to C-4 except for a few minor differences. Ford Automatic Overdrive transmission is slightly different.
Date codes are sometimes included in sections. They are found in various areas and usually consist of 3 or 4 digits. DATE CODE Some parts may include a date code that indicates when the part was produced. If necessary, for larger trucks, additional transmission codes will be printed directly in front of the main transmission code.
A plate is basically a car number plate. The car plate provides all the details related to the car. You can send car number plates and cancel liability insurance if you want to take your car or truck away in the winter. You also need to move the number plate to your new vehicle if you need to use the same plate on the new car.
When dealing with transmission information, this type of transmission is easily the most useful (and clearest) data collection that you can try to get and use together with VIN. There are several VIN schemes that represent vehicles that can be configured with more than one type of automatic transmission, or more than one type of manual transmission. The parts are also known as the suffix numbers.
The police will record details and investigations to find each particle of the car or truck. If you are close enough to the vehicle to find VIN, then you only need to make your own car history report online from many companies. It is important to remember that most Lincoln and some trucks use a 16-inch output shaft (not a normal 15-inch unit) in addition to a longer extension house. Use only synthetic liquids if necessary by Ford. Ford is known for using components designed for one car on various models. If you don’t find a way to decode a VIN on a particular Chevrolet, you won’t be able to verify some components or numbers. Furthermore, it is possible to find VIN in various positions in the vehicle.
The VIN number may be the most important vehicle number. The part number consists of a prefix, a simple part number, and a suffix. The basic part number remains the same, but if the letters of the alphabet are ignored. Ford parts are divided into two main categories: Engineering and Help. The transmission serial number is the manufacturing serial number and cannot be confused with the machine serial number, it is not the same thing. You can receive a series of reports, suggestions, content articles, around the world in a few moments.

C6 transmissions are extremely economical. This transmission seems to simply benefit from an early Toploader, but it is not a performance broadcast at all. If you have determined that a transmission is necessary, we can help you. This transmission is practically identical to that of C-4, with the exception of some minor differences. It cannot be used with a Ford engine. The transmission would also strengthen a larger rear bearing than the automotive version. When you transmit the broadcast Ordera TRANSMISSION EXCHANGE CO, you are guaranteed to have purchased the best.
The other way to recognize the appropriate gear lever is the part number. If the ring needs to be replaced, make sure that the replacement ring fits in the center of the bell tower. If the original bell ring is not worn, reuse it.
You will need a very long tube to acquire the caliber to which you can read it. Ideally, you will have a pressure gauge on the transmission pressure port for accurate indication and correct adjustment. The transmission control pressure must be between 28 and 38 psi.

The 99-04 V-6 units use exactly the same gears as the 90-95 units, but do not provide any speedometer cable since it is completely electronic. There are actually two numbering systems. It is not possible to read with the transmission in the vehicle. Although the transmission can be performed without problems, this does not mean that the TV cable is properly adjusted. Four-speed AOD transmissions are available in four distinct types, each of which takes on a particular panoramic shape. There are many ways to recognize this transmission. Ford Automatic Overdrive transmissions are a bit different.
You can see the full range of products we offer on www.midwesttrans.com. The transmission serial number is a manufacturing serial number and should not be confused with the engine serial number. They are not exactly the same thing. At the moment there are many conversion kits available for CAD trading. The base part number remains exactly the same, however, the alphabetic letters are ignored.

The thrust bearing has been removed and is located at the front of the transmission. Other places to look for a car identification number include various positions under the hood of your vehicle. It’s quite simple if you know what to look for. Both types can appear on each type of transmission because they are interchangeable. From there, count the number of bolts on the drive plate. The big difference between the two is how the teams are managed.
The balance (like the cost of the return) will be evaluated at the end of the work. The increase in size of the Midwest was one of the initial activities that included the final step of the standard test procedure to test manual transmission before delivery. Focus on the strongest transmission profile you can discover, easy to install. How to identify the type of Ford automatic transmission in your car is one of the most frequently asked questions. The 4L60E identification can be a chore because it has been in production for so long.
