I drained the A413 in my '86 New Yorker in late 2011 and installed a new filter and topped it off with ATF+4. I'm going to install another filter, and I'm wondering about fluid, ATF+4 is full synthetic
and I don't see ATF+3 anywhere. I noticed some Castrol ATF for import cars (Honda, Toyota, Nissan) that said in small print on the back that it met the requirements for ATF+3 and ATF+2. Would this be a good choice for an older A413? Anybody running it?
