AOD Trans Options Please... Best MPG In Daily Driver

[texasjammer1]

Hi everyone,

I'm looking for AOD transmission options for my 70 F100. It's a daily driver for me. She's getting 9.5 mpg around town with A/C on.... not good, need much better. I've been reading the blogs about it. I would like to be getting 15-22 mpg if possible.

Here's my config...
-----------------------------------------
69 302 (just rebuilt)
A/C
Power Steering
Edelbrock Performer 289 Intake
Edelbrock 650 Carb
C6 Automatic Trans
Standard Rear End

Can I:
--------------------------------
* Use a Mustang AOD Trans? If so, which ones?
* Use a Crown VIC AOD? If so, which ones?
* Use a converter kit for the existing C6? If so, which ones?
* Use AAMCO for the conversion? Has anyone use AAMCO for converting a standard automatic C6 to a AOD C6?

Should I:
---------------------------
* Use a aftermarket trans? If so, any recommendations?

Appreciate you looking and any advice you can give.

I am planning to run an AOD behind my 408W, but I haven't got close to the mock-up stage, yet. I measured the transmission i built for my '91 Tbird and it measures 30.5 inches from the block face to the rear of the extension housing and another inch to the end of the output shaft. Some have longer extension housings if that would help. 1990 and later AOD's have improved lubrication and clutch capacity. TCCOA has a very good article on upgrading an AOD. That and an overhaul manual and you should be up to the task.

OH! And you will need a TV cable bracket for your carb, AOD's use a kickdown cable instead of a rod. If you need any other measurements, let me know.

You will find a Ford AOD in these donor vehicles:
1980-'92 Ford and Mercury full-size cars with V-6 and V-8 engines
1980-'92 Grand Marquis and Crown Victoria with 4.6 or 5.0 V-8 engines
1983-'86 Ford LTD with a six-cylinder
1984-'93 Mustang and Cougar with transmission code PKA (V-6 and V-8)
1984-'86 Mercury Capri with transmission code PKA
1980-'92 Thunderbird with transmission code PKA
1985-'90 Bronco with 5.0 V-8 engines
1981-'93 Ford pickup and E-vans with V-8 engines
1991-'93 Ford pickups and vans with a 7.3-liter diesel engine
1980-'93 Lincoln (except Versailles) with V-8 engines

In terms of strength and reliability, you want to first find a unit out of a V-8 truck, then a V-8 car, and then a V-6 truck. The V-6 car transmissions are the lightest duty of the bunch. Truck and V-8 car transmissions have the slightly longer tail shaft as well. Also, the 1988 and up units featured better main-shaft lubrication than earlier units. Of course you want to look for pre-1986 transmissions for carbureted vehicles, to have the proper linkage necessary for those cars. Units for 1987 and up were for fuel-injected cars and will have the TV cable activation.

If Possible try to find one from a 1992 or 1993 F150 that came with a 302 (5.0) those are the strongest factory units, and come with the A servo for overdrive, 2 inch overdrive band, and the most clutch packs. Basically it has all the upgrades people add to other aod's. I have a 93 f150 aod and I like it. Hope that helps . Oh Also if you go to junkyards to look for the trans, trucks with the AOD have the shift pattern PRN(OD)D1 C6 and e4od equipped trucks have PRND21 and the e4od trucks will have an od cancel button because it is computerised.
