If u can find a 6,7 or 8 speed (WITH OD) that is a real easy swap to the Packard v8 ENGINE then let us know. i.e. easier than the 4L60E.

BOTTOM LINE: Must be an EASY SWAP!

As Craig points out above the Packard V8 engine simply does not need anything more than 4 speed/OD. I'll even claim 3 speed/OD of which no automatic exists that i know of. Unless one plans on serious racing or pulling Airstreams thru the Rockies on a regular basis. IT's a big powerful engine!

I don;t care if it's 3,4,5,6 or million forward speeds.
Bottom line. EASY swap. Must have overdrive. That simple.

NOTE that the Rear end of the Packard V8 block is rather unusual compared to most V8's since the 1960's. It is the unusual block shroud over the flywhell that makes it more difficult to find a good swap for.
