Aod Transmission

Aod Transmission

The AOD transmission is endlessly reliable when used on stock vehicles. But if a driver decides to make the engine faster, the transmission could end up failing, especially past 450 horsepower. The internals simply were not built to withstand the much stronger forces that come from the upgraded powerplant.

How much horsepower can a AOD transmission handle?

This tended to knock the wind out of the engine’s sails, zing the direct clutch discs or, in extreme cases, even break the inner input shaft. Because of this odd power flow, Lentech’s Len Bertrand tells us a stock AOD can handle 450 hp, at best, and will always be hard on 3/OD clutch packs.

What does AOD stand for transmission?

The AOD (automatic overdrive) is a four-speed automatic transmission, with the 4th gear as overdrive.

What is the difference between AOD and AODE transmission?

the aod uses a cable to adjust line pressure. the aode has a electical connection the right hand side of the trans that controls the epc pressure ,torque converter and shift solinoids.

What year AOD is best?

89-’93 are the best years for the AOD, they already have the better internals for anything with horsepower.

Can you manually shift a AOD transmission?

There is no option to manually shift all four gears. A lot of guys like doing the epoxy mod to the valve body. If you do the epoxy mod it allows you to shift 1, 2 and 3 manually, but will automatically shift into 4th, which is overdrive.

Does Ford AOD need computer?

The Ford AOD does not need a computer to function properly either. The throttle valve function is mechanically activated and the torque converter lock-up function was contained entirely within the transmission case.

How much torque can a Ford AOD handle?

Looking through all the trans build-ups on the Network 54 forums, and TCCOA, etc, the max torque a properly built AOD can handle is about 450 lb/ft.

Are all Ford AOD transmissions the same?

The AODE and 4R70W transmissions were an all-new AOD case designed for electronic interaction with engine controls. The AODE and 4R70W are essentially the same AOD-based transmission.

What years did Ford make the AOD transmission?

Bertrand has plenty of raw material to work with: The AOD appeared in millions of LTDs, Mustangs, Fairmonts, and light-duty trucks from 1980 to 1993. His plan to overthrow the Turbo 400, current King of Performance Transmissions, is a crafty one-Bertrand feels that Ford’s cogswapper has plenty going for it.

What transmission goes with a 302?

For years, the Ford C-4 automatic was a reliable three-speed automatic transmission for many Ford products, and is fine for most 289, 302 or 351 engines that have received modest modifications.

How strong is a Ford AOD transmission?

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 makes a Ford AOD transmission shift?

The longer the pin, the more RPM it takes to shift. Chart attached. The AOD has no vacuum modulator. AOD shift points are controlled by throttle opening via the “TV” or “Throttle Valve” cable in conjunction with the hydraulic flow control in the valve body.
