C6 - FE - E4OD related question.

I dont get around to this forum much, (see FE forum) but here goes.

I have a high performance 390 in my '70 F100. It has a C6 behind it. (aka the 3 speed power sponge). As I understand it, the E4OD is basically a C6 with overdrive. Here's my questions:

1. Does the E4OD have a lockup torque converter?
2. Is it possible to stuff E4OD internals into my C6 case (which has the FE bellhousing bolt pattern)?
3. If so, can I have a lockup torque converter with it?
4. I have 3.70 gears. How high could I take them with the overdrive?
5. How much less power does the E4OD sponge off than the C6?

Still getting ideas. If it's not possible I'll stay with the C6, but I'd rather not run 2500rpm's going down the highway.

Thanks!

Yes.

You can put the gears for 1-3 in it. That will give you a lower first gear, but the same 1:1 high gear. You'd have to lengthen the C6 case to fit in the overdrive. Of course you wouldn't have a hydraulic curciut to engage overdrive....
3. If so, can I have a lockup torque converter with it?
No.
4. I have 3.70 gears. How high could I take them with the overdrive?
The overdrive is 0.71:1, and with the lockup torque converter expect about 40% less RPM with the same axle.
5. How much less power does the E4OD sponge off than the C6?
A lot less, but I don't have actual numbers.

Hrm. So that wont work. Does anyone make an adapter so I can bolt my motor onto an E4OD?

I don't know of an adapter to hook up an E4OD to an FE motor, but if one does exist, you'll probably find it at www.advanceadapters.com or www.high-impact.net.

If all you want is an overdrive gear, look into a Gear Vendors or US Gear add-on overdrive unit. They make both of them to fit the C6. Check them out at www.gearvendors.com and www.usgear.com.

Another route is to swap the C6 for an AOD. There are adapters available to mate the AOD to the FE. I forget the name of the place that has them. A search on the net should reveal it, or contact one of the 2 earlier mentioned transmission sites. The AOD would have to be built to take the 390 torque, but it's still probably the least expensive way to get overdrive in your F100 without going to a manual trans.

Ok so the E4OD is a bad idea. Not a problem, just exploring my options. I'll look into an AOD swap at some point in the future. Thanks again!

Edit: Will I be able to use a lockup torque converter with an AOD?

E$OD's and ignorance

The E4OD BS thown around this site (and others) is disturbing, to say the least. Seems nearly every knowledgable E$OD wrench thinks everybody has unlimited bank acounts and the ONLY solution is rollover and take it the you-know what! My situation is certainly different than yours, to be sure, but doesn't alter the fact that there IS a BETTER way to solve specific E$OD transmission problems without resorting to E$OD butt-F**King. Dump that PoS "Ford" trans idea and take a look at the following solution, SoCalDesertRider:

Type "transmissionadapters" in your URL window (or Google) and scan the site (and look for the GM to Ford FE adapter) The above mentioned adapter allows nearly any GM trans (including the TH400 and 700r4 over drive) to be bolt-up the big blok Ford motors,

Thanks for the reply. I found a good site IMO, http://www.transmissionadapters.com/. If anyone knows a cheaper place (monetarily not quality) let me know.

On the GM issue: It'll be a cold day in that unmentionable place before ANY GM part touches my F100. I appreciate the suggestion, but I'd like to keep my Ford all Ford.

I noticed the site above has an FE to small block ford adapter, so if I do anything I'd use an AOD. Now I know where and how much, so I have benefited from this thread. Thanks.

BeepBeep,

I reallly don't know where you came up with the idea that 'E4OD BS' was being thrown around in this post. Please re-read what I said and then tell me where all this BS is located in my post. Furthermore, your language is atrocious and not acceptable on this forum.

Nevertheless, thanks for posting the transmissionadapters.com website, I had forgotten about that one. Yes, I am aware of the GM trans adapters.

Definately agreed on the language. I tried to ignore it unless someone said something.

GM trannies

Rusty, Ford bought Hydramatics from GM to put in 1949 Lincolns when Ford didn't have an AT of its own.

I am also looking at the adaptor for my Fe to a 700r4, they can be built to handle the tq it just takes dollars. what I realy like is the 3.05 first gear and the .68 overdrive. That means with the 3.54 rear I have in my F100 i could get the best of both worlds, the ability to tow with a low first gear ( nice for the boatramp , and the overdrive to keep them R's down. as long as your not raceing It should perform handly. for high performance I understand the C6 with the wide ratio inerds and needle bearing is the rage.

The C6 is a great transmission! Only problem with it is no overdrive gear . But that's nothin a Gear Vendors OD unit can't fix .

I looked at the gearvenders Od unit. it's what around 2000.00 ? add that to a performance C6 and you end up around 3000.00 - 3500.00

A built 700r4 to handel 450hp 450 Flb's will run around 1150.00 plus the adaptor for 800.00 less than 2000.00, it is not as long at the od C6 and should fit in nicly. Im not nessarly avocating the 700r4 it is just the dollars dont realy add up. A modified AOD would run about the same as a 700r4.
The gearvenders od is a nice quality unit. But when looking at the dollars it seems way high.
