You'll find manuals to be quite rare. I tried to find a 2006 Element (same frame & running gear as CRV) and gave up after months of searching. The other thing about the manuals is that they are geared very low. At 65 MPH the engine is turning 1,000 RPM more than the auto. I've come across articles about how to put an Acura overdrive in the Element manual transmission.
There is no problem with towing the auto. Run it long enough to warm it up, run it through the gears a couple of times, and don't go from reverse to neutral right before towing, always from Dr to neutral. We've got thousands of towing miles on ours and the only problem we've had was self inflicted. (Left the e-brake partially on)
I change 1/3 of the transmission fluid with every oil change but that's the way many CRV/Element owners do their own maintenance. Once you've changed your own you'll understand why.
Our 2008 is the DWs daily driver. She still loves it, fading paint and all. (It's red)
