The 5.0L engine in your Ford LTD was paired with a few different transmission options during its production run. Primarily, it was coupled with the AOD (Automatic OverDrive) or the more advanced 4R70W (also known as the 4R75W) automatic transmission, or the rugged MT82 manual transmission.

Automatic Transmissions: AOD and 4R70W

The AOD (4-speed, produced until 1993) and 4R70W (4-speed, produced from 1994 onwards) are both robust and reliable automatic transmissions that served in Ford's trucks for decades.

To identify which one is under the hood of your 2005 Ford LTD, look for the casting number located on the passenger side of the transmission bell housing. The casting number for the AOD transmission usually starts with "B," while the 4R70W typically starts with "C" or "J".

The AOD transmission was produced from 1981 to 1993. If your Ford LTD is from this period, chances are high you'll find an AOD. However, as mentioned, the casting number should confirm it.

AOD transmissions have a unique, tall tailshaft housing, which is easily recognizable. Additionally, they have a cooler line hooked up to the right side of the transmission and a horizontal mounting bolt pattern.

The 4R70W is an updated and improved version of the AOD, featuring electronic controls and better shift quality. If your Ford LTD is from 1994 onwards, it's likely equipped with a 4R70W.

Like the AOD, the casting number will confirm its identity. The 4R70W also has a distinctive, low-profile tailshaft housing and a diagonal mounting bolt pattern. The transmission cooler line is usually connected to the left side of the transmission.

To identify an MT82, look for the casting number on the transmission's tailshaft housing. The MT82 casting number usually starts with "F". Additionally, this transmission has a long, horizontal tailshaft housing and vertical mounting bolt holes.
