Re: Chrysler transmissions

It was an idea that came out of southern California in the 1970s when "you can't get parts for those" (transmissions). The Torqueflite used is very specific, like 1970-1974, at the time those specific Chrysler transmissions and parts were readily available, now days--less so. The kit was pretty jakey looking, this huge aluminum ring around the bellhousing on the trans, this flanged collar that couples the engine to the torque converter on the T-F. The Torqueflite sat crooked, at an angle in the car in order to make it fit.
These days we either fix the Twin Ultramatic, as there are people (hint: NOT your local trans shop that knows everything about every Big 3 trans) who know how to rebuild them to work correctly, or there are other modern trans adaptions that are a world more professional looking. There is a guy in Texas who adapts GM 700R units to the Packard engine, milling out the top half of the bell housing (among other things) to make a direct bolt up.
The Torqueflite 727 is a really fine transmission, and they took a lot of punishment, but the Packard retrofits I saw just looked like the amateur hour.
