If I remember correctly,. .the 91 had a 4.6 but had the AODE and it used the small block ford bolt pattern. But in 92 they went with a different fully electronic transmission with the 4.6 bolt pattern. The 4R70? Go on Autozone and register,.. then look up the tech manuals for the car.

AOD used a TV cable like the GM 700R4's did. The AODE I know nothing about,.. and even less about the 4R70.
