Cheaper in the long run...
Search Car-part.com for a local JY that has a lower mileage 4r70w.
I paid $450 for a 12k mile Gran Marquis tranny a few years ago. Those are rarer now, lol.
The one going into the Red Cougar is jmodded, has new lines, a cooler, a DirtyD0g TC, and I'm in under a grand.
An 02 is the last year you can be sure will work; you will have to repin the harness, and swap the lever on the side, as well as get the right gear for the VSS sensor on the side.
Being as how 12 quarts of MerconV is over 50 bux, I wouldn't take a 260k mile tranny apart a bunch of times, unless you are rebuilding it; and I wouldn't rebuild that 95 tranny. The new ones have most of the upgrade parts, and have different castings than yours.
Adding a cooler and Jmodding it is also fairly cheap for the benefit; buy one spring and a set of gaskets, drill some holes and you're good!
(Shameless optimism here; this is fairly hard, but you shouldn't have a problem.)
