My tranny just bit the dust last night and I'm about to have it fixed or replace it for a stronger model. What I need to know is what is a "AODE/W"? This is what the big aluminum plate on the passenger side of the tranny says. I always thought I had a E40D tranny. What's the difference?
Also...What tranny would be a good upgrade that can handle 600HP but still be streetable? Will a C-6 swap right in? I plan on going Old-School and ditching the engine I have now with all it's computer garbage and going 460/tunnel ram/two 750 Holleys. Any ideas?

 

It's a 4R70W when used in trucks - AODE is the name when it's installed in cars. The E4OD's new name is the 4R100. The first digit is how many gears it has. The second tells if it's for Front-wheel-drive or Rear-wheel-drive applications. Then the last numbers are how many foot-pounds of torque it can handle, divided by 10. So the AOD is rated for 700lb-ft, and the E4OD is rated for 1,000.

The C-6 has no overdrive, and is weaker than the E4OD.

Losing EFI is the worst move you can make. NEVER put that carbage into any vehicle - the EEC-IV computer is easy to maintain & troubleshoot, and an EFI engine is cheaper to operate and MUCH more driveable.

 

AODE and 4R70W are based on the same transmission case. AODE is Automatic OverDrive Electronic - basically an AOD with electronic shift control.

The 4R70W is a 4 speed Rear wheel drive Wide ratio. It has a wider space between gear ratios than the AODE.

Also, both the AODE and 4R70W are used in BOTH cars and trucks.

 

Thanks for the help, guys. One question that comes to mind is this (for Steve83), wouldn't a naturally aspirated big-block be more cost effective than building the EFI setup when it comes to getting around 600 horsepower? It just seems so much cheaper and easier to deal with to get rid of all the computer crap and go old-school. I hate having a computer limit what I do on my rig!!!

 

No, it's still cheaper to chip it. But I think you'll find that if you run a stock EFI, you'll ALWAYS get top performance out of it, and you won't NEED to build a 600hp carbed engine to get the stock EFI's rated 200hp every day.

 

What year truck are you working on?

The AOD/AODE/4R70W is not a very strong tranny from the factory, but they can be built up to handle TONS of power.

If you want a bullet proof AOD/AODE check with http://baumannengineering.com/ They also have 4R70W, but I don't know how they build them up.

For a 4R70W that is bulletproof, check with http://reinhartautomotive.com/index2.ivnu Dennis Reinhart builds the 4R70W to the specs given by one of the original designers of the transmission. If you would like to see how to bulletproof the 4R70W, go to http://tccoa.com/articles/tranny/index.html and click on "Ford OD Transmissions 101"

As far as a computer chip goes, Reinhart Automotive custom burns chips for the Thunderbird/Cougar crowd that helps with transmission shifting and longevity. I don't know if they do trucks, but it wouldn't hurt to call and check.

Hope this helps a little...
