I'm running a Baumann Quick4 on the 4R70W that is mated to the 390 in my 1970 F250.  Very pleased with how it works.  The supporting software makes it easy to customize the shifts to match the engine and drivetrain.  The only issue I had initially was the tach signal from my Pertronix unit but they have a filter that installs easily into the harness if needed to clean up the signal.  The harness was easy to work with and of high quality.  Since I am messing around with different driveline configurations, I ended up using an electronic to mechanical speedometer system.  The Baumann has a speedo output signal that works well with different electronic speedos.  If you have the right year 4R70W you will likely still be able to use a regular speedometer cable.  By going electronic you can also go with the 2003 (ish) or newer units that don't have the speedo drive on the output shaft. 

I'm running a quickfuel carb and ended up converting a Holley TPS unit.  The choke mounting was actually a little different than a Holley (even though Holley said it was the same) but I was able to make it work.  If you are going to inject your truck I think you can just tie into the TPS circuit.
 
All in all, the truck runs great with the 4R70W.  Since a 445 stroker is under construction, I may swap the 4R70W with a 4R100 for a little better torque rating as this will be my post-retirement tow vehicle - I have two junk yard 4R100 specials in the garage waiting for a rebuild.
 

Nothing specific on the 2.

My coworker found the multiple program function of the model 4 handy.  You can load different programs for different driving, and change between them on the controller itself.  Can’t do that on the 2.

Also, the 4 lets you lockup in multiple gears if desired.

Think of this, you can have a nice easy cruising program, then a drag race program, autocross program....

Don't know anyone who's tried it, cheaper though.

I wish I only had $790 into my AOD to get it running

For those of you contemplating an OD trans, the 4r70w is the way to go. By the time I bought the AOD, TC, hardened input shaft, valve body, red Alto frictions, kolen steels, all to make it as strong as the 4r70w, with less tuneabiity, I was in it for $1,700.

I thought I'd get away on the cheap, but once I was into it, well,  ya know.

It doesn't take a rocket scientist.

i ran a 96 tbird v6 256000 miles on the original transmission, didn't do anything besides change oil and filters. Should hold up. Still going strong when i got tired of driving it.
 

I have been watching and reading about the 4r70w transmission , I would like to switch from 3 speed auto to overdrive , The AODE 4r70w looks to be the way to go. As for controller I will continue reading and watching. Also watched a few videos on tear down and rebuild on the 4r70w , The guy built all the tools needed for tear down. It looks like something that a person could do as far as the rebuild if needed.  

The guy at Baumann told me the v6 converter used with the 3.70:1 rear gears would work quite well. He did not recommend that I change the converter.

Fat fingers converted my 56 F100 to a 57.
