What is the difference between AOD and AODE, 4R70, 4R75 Transmissions?

The transmission pan bolt pattern for the AOD is slightly different than that of the AODE, 4R70, 4R75. It is important that you identify which transmission you have so that the pan you order will have the correct bolt pattern.

The AOD transmission was used in many rear wheel drive Ford vehicles from late 1981 through early 1993. The AODE transmission was produced for model years 1993 and 1994. Production of the 4R70 also began in 1993 and by 1995 it replaced the AODE. The 4R75 designation began in 2003.

AODE, 4R70, and 4R75 transmissions have a large electrical connector on the passenger side of the transmission just above the transmission pan. They also have a neutral safety switch mounted on the selector shaft on the outside of the transmission case on the driver’s side just above the transmission pan.

AOD transmissions have an internal neutral safety switch. A cable connects the throttle body to the transmission to downshift the transmission on full throttle acceleration. The AODE, 4R70, 4R75 do this electronically.

Remember: When you order, you must select AOD or AODE, 4R70, 4R75 in the shopping cart to get the correct bolt pattern on your pan.
