Gear Ratio of Ford AOD Transmission
The gear ratios of the Ford AOD (Automatic Overdrive) transmission are as follows:
– 1st gear: 2.40:1
– 2nd gear: 1.47:1
– 3rd gear: 1:1
– 4th gear (overdrive): 0.67:1
The 4th gear in the 4R70-W version of the AOD transmission has a ratio of 0.70:1, which is slightly higher than the standard AOD’s 0.67:1 ratio. This higher ratio provides better mechanical advantage, leading to improved take-off and passing acceleration, slightly lower fuel consumption, and better gearset strength.

How much horsepower can the AODE transmission handle?
Installation of the Valve Body kit will allow 1997 and earlier AODE/4R70W transmissions to perform reliably in a 350 to 375 horsepower application. 1998 and later 4R70Ws can handle up to 500 horsepower with just the addition of the Valve Body kit.
What is the difference between AOD and 4R70W?
What makes the 4R70W different from the AODE is lower gear ratios in first and second gears, which improve acceleration. The 4.6L Modular V-8 engine needs this feature more than the 5.0L and 5.8L pushrod V-8s because the 4.6L doesn’t have the same torque curve as a small-block.
What is the gear ratio of AODE vs 4R70W?
The 4R70W is little more than the AOD-E with 2.84:1 first gear, 1.55:1 second, which makes it a great candidate for the holeshot. It gets you off the line more quickly than the AOD/AOD-E. Overdrive is better too at 0.70:1, with lower cruise rpm around 2,000 rpm at 70 mph depending upon axle ratio and tire diameter.
How many gears does an AOD have?
four-speed
The AOD (automatic overdrive) is a four-speed automatic transmission, with the 4th gear as overdrive.
What gear ratios did the Ford Cruise O Matic have?
First gear could only be engaged manually in Low (though it could be engaged if the car was in motion, but would only downshift) and was used for engine braking or rapid starts. Gear ratios were: 2.4 – 1.0 for the torque converter, 2.84 for first gear, 1.68 for second, third was direct and reverse was 1.72.
What is the ratio of the Ford AOD?
The OD ratio is a cushy 0.67:1, so you can effectively knock a 4.11:1 gear down to a jaw-dropping 2.75:1 when you’re on the open road.
How strong are AOD transmissions?
The bulletproof nature of the Ford AOD transmission can be unraveled just by knowing the right buttons to push. When that has been put in place, you can boost its performance from about 400 hp to as high as 1,200 hp which makes for excellent speed while racing.
What year is the best Ford AOD transmission?
1992-93 E and F series trucks (those with AOD’s and not E4OD’s) contain the strongest production AOD transmissions.
What are the specs of the AOD transmission?
The AOD weighs 150 pounds, about 40 lbs. heavier than a C-4 or C-6 transmission. Shift ratios are: 1st, 2.40:1; 2nd, 1.47:1; 3rd, 1.00:1; OD, 0.67:1; Reverse, 2.00:1. These ratios are very close to the 2.46:1 ratio used in the three-speed C-4 and C-6 transmissions, but with the added benefit of an overdrive.
What is the best year for the Ford AOD?
But the absolute best Factory aod is going to be from a 1992 or 1993 F150 that came with a 5.0 v8. It has all the strongest features like the 2 inch od band, the a servo for od, and the v8 clutch packs.
