Best Automatic OD trans swap for A body car

This has been posted before on here....lot of guys wanting O/D apparently...

I have talked to Phoenix Transmissions from Texas (www.phoenixtrans.com)....along with a few other places...700R4 is the easiest without major modifications...overall length of a 700R4 is 30 3/4", compared to 30 1/2" of a 904......so, you probably could get by with your existing driveshaft....face to mount distance (from front of housing to rear trans. mount) between 700R4 and 904 is 1 1/4" difference, but it is different on some 700R4's...they know what year 700R4's are comparable, or search the web yourself....all you would need is an adapter for the front mount and some mods on your rear tranny mount, but there's probably companies out there that sell the rear modified mount too....Phoenix Trans. quoted me $22-2400 for the tranny, mount, mounting kit, basically everything but a converter, and it requires no floor modifications like the A518.

I have been considering this for awhile, but I'm not ready to sink that kind of money in it....I hope to do mine in the near future.....
