Default Re: I want a Automatic with overdrive in my T-Bird

I wouldn't be afraid to run the 3.31 gear with an aod. Have had several Grand Marquis and a couple Town Cars that came with 3.08 gears. The cars were probably heavier than a Tbird and had some tall tires also along with the mighty lopo 150hp 5.0 .
