I agree with you Dave as my research has gotten the same results, no install=no warranty AND it only saves a few hundred. The Jasper research was interesting in that they have whole paragraph on the importance of flushing the original system with a "hydraulic shock flusher? The more I read, the more I am leaning towards expensive but safe install by a local transmission place.
I believe some of the rebuilders send a inline filter and require you to install it in the line for a warranty. Dirt and shavings in the cooler must be a big problem. Almost seems like money well spent to get a new radiator if you are going to spend thousands getting the trans rebuilt.
The Jasper idea may be just the ticket, I gotta look into the complexity of an R R.
Thanks for the input
I would rebuild what I had before I would get a Jasper rebuild. The reason is because of the same problems associated with rebuilt/remanufactured carburetors: Ford calibrated these parts for *specific* vehicles, and it's not uncommon to get a rebuild made for a different application.
Ford used the AOD behind a lot of vehicles for a lot of years. The valve body is calibrated for a *specific* vehicle and weight. There is a very good chance you won't get the correct valve body calibrated for a truck. For example, you may get one from a Crown Victoria. It will work of course, but not as well and it might not hold up as long.
For the reasons Franklin2 mentioned, I would not go through the trouble of R&R, either. Get a local transmission shop to rebuild your existing AOD. Since the fill plug is still in the pan, you still have the correct one that hasn't been touched yet.

2X on above, as I have experience with putting a 302 AOD tranny behind a I6 300 engine. The 302 V8 AOD is "programmed" for a higher engine RPM shift point than the 300 I6. The poor I6 wheezes out at 4K RPM while the 302 goes o 5.5K. The shift points also are not favorable to the I6 engine's low torque curve and expects the higher RPM of the V8.
In a nut shell, it will work but not as best as it could be.
