Waine5550 Posted November 18, 2022 Share Posted November 18, 2022 Did an Efi delete all good with the motor but having issues with the AOD. We can't get the pressure down. Its at 50 psi. What am I missing? Link to comment Share on other sites More sharing options...
Gary Lewis Posted November 18, 2022 Share Posted November 18, 2022 What have you done to get the pressure down? Have you adjusted the TV rod? Link to comment Share on other sites More sharing options...
Waine5550 Posted November 18, 2022 Author Share Posted November 18, 2022 What have you done to get the pressure down? Have you adjusted the TV rod? Yes. Using the lokar cable. Has all kinds of slack now. I understand it's a balance to much is as bad as not enough. It won't go past 2nd gear. Link to comment Share on other sites More sharing options...
85lebaront2 Posted November 19, 2022 Share Posted November 19, 2022 Yes. Using the lokar cable. Has all kinds of slack now. I understand it's a balance to much is as bad as not enough. It won't go past 2nd gear. Is the outer TV lever going all the way to the closed throttle position? The AOD has an internal "fail safe" spring in case the rod or cable come off. I assume the Lokar cable pulls on the TV lever as it usually hooks on the tail of the carburetor throttle lever. The EFI cable would have been the same way, pulling the TV lever as the throttle was opened. Link to comment Share on other sites More sharing options...

Where is that spring located? And thank you. Might have to change that name? Link to comment Share on other sites More sharing options...

Gsmblue Posted November 19, 2022 Share Posted November 19, 2022 Is this the spring? Following. I have an aod that has never worked properly in my Bronco. I have the same issue with the high static pressure and using the lokar cable. In my case i can get all the gears but it shifts very late and I don’t like the smell. My transmission work is on hold till the spring - hoping you find a solution!! Link to my posts on tv cable issues, maybe it will help, maybe not. https://forum.garysgaragemahal.com/1982-Bronco-351-4x4-Code-name-Esperanza-tp9221p120841.html Link to comment Share on other sites More sharing options...
85lebaront2 Posted November 19, 2022 Share Posted November 19, 2022 Is this the spring? Here is the internal torsion spring in the AOD, it moves the TV shaft in the counterclockwise direction. In order to get a positive complete return to the minimum pressure, the rod needs to be pulled up and forward or the cable needs to have the lower end pulled out to find the internal stop for the TV lever.
