First pull: a little 28' TT going about 100 miles. Even though the weather was cool (max ~60°F), the temperature gauge came up for the first time. After ~45 minutes doing ~70mph, it got about to "R", and the transmission started acting up. So I let it cool for a few minutes & finished the trip. I haven't changed the ATF or filter yet, or upgraded from the (tiny) factory cooler, or added an inline filter. But they're all high on the to-do list...
