How to Exchange Ford AOD, AODE, 4R70W Transmission Linkage
Monster Transmission Presents Curt's Corner and How to Exchange Ford AOD, AODE, 4R70W Transmission Linkage
Monster Transmission Presents Curt's Corner as Curt goes over how to exchange the lever arms for the Detent or TV Cable Rod.
This process and principle will apply for the Ford AOD Transmission, Ford AODE Transmission, or the Ford 4R70W transmission.
In order to change the linkage you'll have to change it from the inside of the pan. There are 16 different linkage arms offered for an AOD Ford Transmission. So there are a lot of variables, such as 2 wheel drive, or if it's a truck, or a Mustang, etc...
If your transmission is built by Monster Transmission we will provide the specific linkage system that you request.
To start the process you'll remove the pan, and for a little more room to work with the transmission filter as well. Then the transmission valve body is exposed and you'll be able to access your internal shift linkage system. In the linkage Monster Transmission during a rebuild will add an extra component to prevent the shaft from going behind the TV rod. Once inside you'll first remove the rooster tail which has an 8mm bolt. Then under the rod there is a 13/16" nut that you will loosen that will release the tension off of the shaft.
Then a roll pin that fits inside of the casting of the case. This prevents the rod from sliding out of the case. You can use cutting dice or needle nose pliers to remove it.
Once that pin is removed the linkage will pull out after removing that 13/16 nut that was previously loosened. Then you can slide the linkage out of the case. The new linkage will then slide over the TV shaft, and line the rooster tail up with the linkage. The 2 flat lands are equal on both sides so it could be placed up or down. Then tighten the 13/16 nut on the new shaft. Before tightening all the way, make sure the linkage is all lined up. If you miss the valve you won't have any movement at all. So make sure its lined up correctly. Make sure the valve and that the TV system is correctly attached. Then install the roll pin and tap it into place, not too far down though so you can remove at a later time if needed. Then there is a spring back behind the TV valve rod you can pull it around and rest it against a shift place on the valve body. Then reinstall the rooster tail tensioner.
Then its re-install it and test to make sure all linkage works properly.
Also verify the TV Bracket is attached correctly and springs back, then reinstall the transmission filter and filter gasket. Then last but not least the pan gasket and transmission pan.
