Going to change transmission oil in my 73 New Yorker is ATF +4 the best choice.
Your '73 still has a drain plug on the convertor, so be sure to drain the convertor as part of the oil change.

Pardon my ignorance, Dave...but where is the plug? Bellhousing?
Thank You,

oil change
Ok so here's a trick question. My new converter came w/o a drain plug. Can one be installed by drilling and tapping a hole? Or does it have to be a welded-on bung?
I think in all the years of working on old mopars I have only ever had one torque converter that actually HAD a drain plug, so if you don't find one it's not that strange.
@Mike66Chryslers and @Davea Lux (and others) -- I have been using B&M Trick Shift transmission fluid as the ATF for Medina and Poppy. Any comments?
@T5 copper -- welcome to the club of '73 Chrysler owners. Any chance you'd post pics of your NYer? Here are a few photos of Ming, which I acquired a couple of months back from a collector's estate. She should be back on the road this coming June.
