I was perusing my swapped vehicle owners manual, a 1987 TBird, and I saw the OD button function on the shifter. I pulled the 5.0/AOD package for my 73, but I don’t remember seeing any button when I disassembled the car. Did the 87 AOD behind the 5.0 have the capability for that No OD feature? Thanks for the help.

P.S. I wasn’t sure where to post this; I had it posted on my 71-73 Mustangs site, but there was no interest in the question.

To my knowledge there is no OD button in any of the T-Birds. The center console shift selector from a 87-88 Sport 5.0 car should have P R N OD D 1. Shift selector in a Turbo Coupe 2.3ccar came with P R N OD D 2 1. Forum dedicated to the Fox T-Birds and Cougars is here:

Thank you. Weird that it’s in the 1987 TBird owners manual as “optional equipment.” I have a 5.0 AOD. Fo you happen to know if I select the D position, my car will only run through the 3 gears and not use the OD gear?

Correct. D will only allow gears 1-3. OD will almost shifting into 4th (overdrive)

Thank you so much. That’s what I really wanted to do, so a switch or a gear selector, I’d choose the gear selector anytime. Appreciate the help. Steve

To get 2nd gear to hold it was called the 1-D-1 shuffle. You start it out in 1 then upshift to D and then downshift to 1. The transmission will shift 2nd and hold it. To go to 3rd simply upshift into D.

Anyone jump in and correct me if I misspoke as it's literally been over 20 years since I have driven an AOD car.

I’ve read the same thing. I was just trying to find a way to drive it with just 1-2-3. With a rear axle of 2.7, I’ve got a very low 50mph rpm. I’m driving it around town and it shifts to OD very quickly. Thanks again for the help.

This era of OD transmissions were known to have transmission problems from not locking out OD when driving around town......
