  1. How do I install an AODE or 4R70W into an early mustang?

  2. What parts do I need to install an AODE or 4R70W into a fox body (1979-1993) mustang?

  3. I have a 86 f350 with a 6.9 diesel. What would I have to do to put a AOD or E4OD in place of my C6

  4. I have a 1988 f250 4x4 with a 460 and I do some heavy pulling with it, and would like to retrofit it with a E4OD. What year of trans and what modifacations would be the best for making this a good and reliable as my C-6?

  5. I have a 1977 ford truck and I am putting a 1978 460 engine in it. I would like to have an overdrive transmission and have cosidered the E4od. Do you have the controller for this transmission? What all will I need and how much is it? Thanks Chris

  6. I was told by my transmission rebuilder that using an AOD tailhousing on a 4R70w transmission will allow the use of the stock AOD crossmember on a Fox-body mustang.Is this true?

  7. I have a '95 mustang GT with an AODE which is having problems, so I would like to replace it with a 4R70W from a '98 or newer mustang due to the higher power capacity of the newer transmission. Which engines have the same bolt pattern as the 5.0 and which valve body kit would I use, the one for the year of the transmission or the car? Thanks for your help.

  8. Can you tell me if an 89 Mustang AOD will swap into a 89 Mark Vii lsc? Thanks

  9. I have a 94 mustang with a 3.8 auto trans.,which is bad I want to put a trans out of a 90 cougar same engine.Will it work and what all will have to be changed? I have a tranny out of a 97 but the interchange book say no way. Hope you can give me some good news car has been on blocks for 9 months

  10. Can I use any trans other than one out of a 94 or 95 mustang in my 94 mustang without having to go through all kinds of crap?







  1. How do I install an AODE or 4R70W into an early mustang?

    One of our customers has an excellent website detailing the entire process of installing a 4R70W into a 1965 Mustang Convertible.

  2. What parts do I need to install an AODE or 4R70W into a fox body (1979-1993) mustang?

    You will need the following items:

    • AODE or 4R70W transmission with the proper bolt pattern for your engine.
    • Baumanator TCS
    • Dipstick tube and dipstick from a '94-'95 AODE equipped Mustang (may not clear all headers)
    • Backset transmission crossmember
    • flexplate from AOD equipped fox body Mustang (imbalance weight must match engine 1968-1980 302 = 28 oz. 1981-2001 = 50 oz.)
    • shifter cable from 1994-95 Mustang
    • transmission inspection plate and transmission to engine block separator plate from an AOD equipped fox body Mustang
    • If the AODE or 4R70W transmission you sourced is from a Mustang it will have the correct shift lever if not, you will need a shift lever from a '94-'04 Mustang application.

    Obviously, if you are converting from an AOD you will have most of these components. The other components are listed here in case you are wisely changing from a manual trans to an automatic.

  3. I have a 86 f350 with a 6.9 diesel. What would I have to do to put a AOD or E4OD in place of my C6

    The only overdrive transmission Ford made that will bolt to your vehicle is the E4OD. I wouldn't recommend the AOD for a diesel application, even if they do make an adapter. You would need the E4OD with the diesel bolt pattern, and our Baumannator TCS since this transmission is electronically controlled. You would also need to adapt the shift linkage from your truck to the lever on the E4OD. 1989 and later Ford trucks were available with the E4OD, and would be a good source for shift linkages, transmission mounts, and crossmembers.

  4. I have a 1988 f250 4x4 with a 460 and I do some heavy pulling with it, and would like to retrofit it with a E4OD. What year of trans and what modifacations would be the best for making this a good and reliable as my C-6?

    Any 1990 and later E4OD with the big block bolt pattern would be fine for a core for your truck. You would want to use the hard part update kit from our E4OD Products Page, and install a new front pump and solenoid body. You could build the transmission to stock diesel specs, or go with aftermarket clutches. You would also need our Baumannator TCS to control this electronic transmission.

    We do have a controller for this transmission. You can order it with a harness that plugs directly into the transmission. For current pricing see our Electronics Products Page

  6. I was told by my transmission rebuilder that using an AOD tailhousing on a 4R70w transmission will allow the use of the stock AOD crossmember on a Fox-body mustang.Is this true?

    No, this is not true. Using the AOD extension housing on the 4R70W will allow the use of a slip yoke from an AOD equipped car (the drive shaft may still need to be shortened), but the transmission mount bolt holes will still be farther back. The reason the AODE and 4R70W transmissions are longer than the AOD is that the torque converter is thicker (because of the lockup clutch) so the bellhousing has to be deeper. The Deeper bellhousing pushes the entire transmission case back. The length of the AOD and AODE/4R70W extension housings are the same.

  7. I have a '95 mustang GT with an AODE which is having problems, so I would like to replace it with a 4R70W from a '98 or newer mustang due to the higher power capacity of the newer transmission. Which engines have the same bolt pattern as the 5.0 and which valve body kit would I use, the one for the year of the transmission or the car? Thanks for your help.

    The 3.8L and 4.2L V6 engines have the same bolt pattern as the 302. Also you can find the 4R70W behind the 5.0 liter in the 1998-2001 Ford Explorers and Mercury Mountaineers. Keep in mind that the factory electronics in your car WILL NOT run the 4R70W properly. You would need the Baumannator TCS Electronic Transmission Controller to run this transmission in the AODE equipped Mustang. If you use the factory controls the torque converter clutch will not engage. The factory computer will think the converter clutch is slipping due to the lower overdrive gear ratio.

  8. Can you tell me if an 89 Mustang AOD will swap into a 89 Mark Vii lsc? Thanks

    The transmission will certainly bolt up. You may have to swap shift levers or TV levers on the case, but making this swap should be pretty easy. All AOD transmissions have the same bolt pattern, and swapping the levers is easy. The only thing to watch out for is that the output shaft length is the same for both transmissions because this cannot easily be changed. Measure the extension housing of both transmissions to be sure they are the same length, and if they are you can make the swap.

  9. I have a 94 mustang with a 3.8 auto trans.,which is bad I want to put a trans out of a 90 cougar same engine.Will it work and what all will have to be changed? I have a tranny out of a 97 but the interchange book say no way. Hope you can give me some good news car has been on blocks for 9 months

    You would have more money invested in making either one of these transmissions work in your car than it would cost to rebuild the one that is currently installed. The 90 cougar used an AOD, which would require TV linkage to be added to your car, and possible changes to the shift linkage. Also the PCM (Powertrain Control Module) would not continue to operate the engine properly without the transmission connected to it. If you use the 4R70W from the 1997 model your converter clutch will not engage because the computer will think it is slipping due to the lower gear ratio of overdrive. Some vehicles also won't make the 1-2 shift at WOT once they are changed to the 4R70W. The only way to make the 4R70W work in your application is to use the Baumannator TCS. This will make the transmission work, but you will still need to make your PCM run the engine properly by following one of the methods mentioned in the FAQ about using the TCS with a vehicle factory equipped with the electronic transmission.

  10. Can I use any trans other than one out of a 94 or 95 mustang in my 94 mustang without having to go through all kinds of crap?

    You need to get a true AODE transmission for your mustang. It would have to be from a 1994 or 1995 vehicle because the AODE gear ratios are no longer produced from 1996 and up. All 1996 and later transmissions are the wide ratio 4R70W type. Also the first year the AODE was produced with the 302 bolt pattern was 1994. The wide ratios were also produced in 302 pattern in 1994 and 1995 so be sure you get the right gear ratios and the right year. The truck transmissions are wide ratio in 1994 and 1995 so avoid those. Wide ratio transmissions will have a large W cast on the extension housing for easy identification.
