can anybody tell me were the closest place to brisbane, were i can get a reconditioned fuly aotomatic gearbox from afast back etc . cant be from a van as its for a trike. appreciate ysome help.

Try German Auto's or Mick Motors. I may have an auto or two but they aren't re-conditioned. Last one I got reconditioned cost around the $1200 mark.

seagull is selling a full trike kit with a type 3 auto!!
Definitely worth looking into, save a lot of work!
