AOD transmission on a 390 FE

I'm considering replacing the cruisomatic in my 63 Galaxie with an AOD. It has the 390 FE. Has anyone done this and if so what kind of pitfalls are associated with the swap? Thanks one and all for any info you can provide.

AOD transmission on a 390 FE

That's a fairly serious replacement. You might want to check the Ford tranny forum for some additional advice to those who respond here. I believe you'll need an adapter for this swap; you can take a look at www.transmissionadapters.com.

Just outta curiousity - why do you want to switch from the cruso to the AOD?

AOD transmission on a 390 FE

The cruisomatic needs some work and I'm gonna have to pull it and have it rebuilt. I have an opportunity to get a free AOD and torque converter, so I'd just like to compare the costs of having the cruiso rebuilt to replacing it with the AOD and if the benefits are worth the cost. I believe the AOD would give me better mileage than the cruiso but I could be wrong. Also the car originally had a column shifter and bench seat and I would like to replace them with a floor shifter and bucket seats but I haven't had much luck in finding a quality aftermarket shifter for the cruisomatic. Nothing's set in stone though, I'm just considering it right now. Thanks for your input Sean.

AOD transmission on a 390 FE

I just bought one myself. I decided not to go with the adaptors and buy an AOD separately as I figured by the time I get in to it for a little more I could have a built AOD with a custom FE bellhousing by Lentech. They are the premier AOD builder for the late model Mustang world. They make an FE bellhousing that comes bolted to the AOD but you can only buy it with their AOD.

It's not cheap though but I figured I would do it right this time since I wasted a lot of money trying to get my Cruise-o-matic working.

also just to let you know a stock AOD will be torn apart by a 390 you need one that is built up a bit

dbu8554 brings up a good point. Well, I'm in the process of building a c6 for my 390. I love c6s; they're not bad to rebuild if you take your time, and there's a lot of options available. Unfortunately, the Crap-O-Matics that I've had rebuilt in the past by reputable shops went downhill within a calendar year of the rebuild.

Anyway, the AOD will give a bit more economy (I base this opinion solely on what I've read from folks who've made the swap), but dbu8554 is likely correct about the buildup.

I don't know if he's still on the fence or if he went another route, but I believe (unless I'm making this up) that wildo was gonna put an AOD in his '65.

AOD transmission on a 390 FE

I have AOD behind my small block in the '66. Works great. Then again, I am not putting out a ton of power and have no intentions on doing anything more than street driving.

You should also check the drive shaft length requirements.

My car is in the shop now for a rear gear change. It's up to a 3.73 and needs to go closer to 4 or maybe 4.11 (the shop guy will decide). I've been turning right around 2000 rpm at 70 mph. I want the engine to work a little more.

Also a good time to change the U-joints that I thought were already changed.

Agreed. Even if you have a stock 390 it has a lot more torque then a stock AOD is used to.

What rearend ratio are you running? You may be better off to run a C-6 with a higher rearend ratio.

In the flat land that live in, it just may be the best, and most least expensive option.

You would be better off with a C-6 you know... The 425 ft lbs of torque put out by the weakest 390 is a LOT for an AOD... Plus the AOD and the Cruise-o- and the C-6 all weigh relatively the same... (Heavy! )

AOD transmission on a 390 FE

C6 is a lot easier of a swap. Still stinks if you have the stock console though. I had to remove my stock floor shifter and console and go with a B&amp;M shifter with the C6. If you are a machine shop guru you could probably fab something to make the linkage's work together, if not, you'll end up with a B&amp;M or Hurst shifter. They don't work with the stock console. By the way, the cruis-o is a pig! I noticed almost as much of a difference in power by adding the C6 as I did swapping out the stock 390 for a 431 stroker. You can build an AOD to handle the 390 but it won't be free. By the way, the "Built" cruiso with stall convertor lasted only about 100 miles with the new motor.

Do some more research and then make the swap. You probably already know that making one change will undoubtedly mean atleast 3 more things that need to change Good luck.

AOD transmission on a 390 FE

If you are going to pound on your transmission, a C-6, even a stock one with a shift kit is the way to go.

In your case where over drive is required, the AOD is pretty much the cheapest over all option. It'll run you around $2K + to get a unit capable of handling the torque, but its a one piece unit. The E4OD is not really an option, you have to cut up the floor pan to fit it in a 60's car. Its a monster in size and really works best with a computer. The other overdrive option is a GV (gear vendor) overdrive which bolts on the rear of a C-6, its a great choice - but it runs about the same (a couple of hundred less than 2K), but you still need a built C-6 to hook it to.

Fora picture see the link below, its about 1/2 to 1/3 down page, Combined it gives about 20% overdrive, 30% milage: http://www.transmissioncenter.net/c4_c6.htm

There is a difference in cruisomatics, they have a few different sizes, the Large case cruisomatic, put in Lincolns and some Mercurys, was the transmission the racers used before the C-6 was available. Problem is - not too many know how to put them together, to make them last, anymore. They have a tendancy to crack the case if abused.

C-4 and AOD are lighter, don't rob as much horsepower as the C-6. But, my personal opinion, they need a lot more PM ,preventative maintenance, to keep in top shape behind a high torque/HP, street application. Some guys swear by them, but I just can't let go of the big block needs a C-6 mantra. As mentioned Lentech has been building and selling coversions for use with FEs for a few years, they are pretty much at the top of the list if thats the way you want to go.

Bottom line: For the lowest cost, best value when overdrive is required ... The AOD is probably the better choice.

Behind a more robust engine, or more abuse with intent to do harm ...I would say look at doing it in stages. Get a strong C-6 built, then save up your pennies for a GV overdrive unit later on. It costs more, is heavier...but if they can survive behind 40 ft+ RVs, they should be a better lasting value behind a high torque, high horsepower streeter - if you need to take longer trips.

Obviously - these are Opinions only. You need to decide what is better for you - what fits your uses.

AOD transmission on a 390 FE

FYI.... gear vendors site

http://www.drivetrain.com/new_overdr...d3spdauto.html

FORD 3-Speed Automatic Performance Car/Street Rod

At about 2200 dollars (depending on models) the Gear Vendors is not the cheapest way for you to get overdrive (a rebuilt wreaking yard AOD is probably cheaper) but the Gear Vendors is by far the best way. Horsepower handling is the first issue. A Gear Vendors will handle 1200+ horsepower reliably. This is why you have seen Gear Vendors in 8 second 1/4 mile cars in publications like Hot Rod and National Dragster. This is also why all GM Callaway Corvettes with automatics came with a TH400 and GEAR VENDORS instead of the 700r4 which is the base Corvette trans. and comparable to the AOD Ford. If you’re running more then 1200 horsepower (and we have customers that are) then talk to us at the factory as there are some hydraulic changes we do for vehicles up to 2000hp.

Horsepower aside, there are several other reasons you will prefer a Gear Vendors to any factory overdrive automatic. You will have a dashswitch that allows both manual ad automatic operation. With the switch in “auto” the vehicle will act just like it came from the factory with overdrive. The overdrive will kick in at 47 mph or whatever the EPROM is set for in our electronics and turn back off at slower speeds without attention of the driver. The ratio is .78 to 1 (see the final drive ratio charts on page 17). This equates to 28% faster vehicle speed at the same rpm. Or, take your existing rear gear multiplied by .78 (i.e. 4.10 X.78=3.20). In this example a vehicle with a 4.10 behaves just like it had 3.20s when the overdrive is engaged. This is just the right amount of overdrive as any taller would require a lock up converter or create excessive converter slippage. With the .78 to 1 ratio you’re good with any torque converter you chose for high performance street/strip use.

Another great feature of the Gear Vendors is that you will have a full 6 forward ratios when you switch to manual on the dashswitch. Pull into low, accelerate, then hit our button (on the shifter or the floor), a green light appears indicating overdrive and your in first over which is right between 1st and 2nd . Then shift to 2nd and turn us off. Then rev back up and hit the button for 2nd-over. Then 3rd and 3rd-over. See more information on Gear Splitting in the Drag Racing section. The performance and sound of the motor is tremendous as it goes through 6 full throttle close ratio shifts. You are in each gar 1/2 the time you are now so the car is not only faster but it also feels and sounds much faster.

AOD transmission on a 390 FE

Thanks one and all for the input. This car is my retirement project and I'm not trying to make it a high performance drag machine, I just want to make it a good dependable daily driver with a little bit of extra street ooomph. It had been sitting in a barn and was full of rat nests when I got it, but I cleaned it up and drove it as is for a couple of years. I started replacing and trying to improve things as money allowed (and I'm sure you all know how that goes). I replaced all the front bushings, springs, tie rod ends etc. and put disk brakes on the front, now I want to start on the engine and drivetrain. The engines coming out and getting a rebuild and I haven't decided what to do as far as the transmission goes. I looked at the Lentech site today and they seem to have a high reputation for building the AOD. Also looked at the adapter plate kit to mount the AOD on the FE. The AOD I was gonna get for free fell thru (it was out of a 5.0 Mustang the guy used for racing, now's he's decided to put the engine and tranny in his Jeep) so if I go that way I'm still looking at $700 for the adapter and another what $1200 to $1500 or more for a good built AOD and torque converter. Right now from all your input I'm leaning towards the C6. I don't know what gear ratio the rear end is. The shop manual lists rear gear ratio's anywhere from a 3.00 to a 4.11. I'm thinking it's probably somewhere in the middle, maybe a 3.56, but I don't know for sure and the only way I know how to find out is pull it and count the teeth. So I appreciate all your advice and tips and thank every one of you.
