Tony96EX,
Hmm, I have no idea about synchro prices.
I assume once you have the tranny out, you would need some sort of gear puller. And a cherry picker to lift the puppy out of the engine bay. Other than that, your regular hand tools should be plenty. Zoinks, you'll have to pull the axles and all as well...
I've never been in a Honda tranny before either. I'd suggest trying the oil first though.
