Yes, with enough money anything is possible.
Yes, it would be a lot of work, though.
Yes, you'd have to find the stock automatic transmission for your year and engine size, the stock automatic brake pedal assembly, and miscellaneous small things like transmission fluid, the transmission dipstick tube, linkages, etc.
If the Prelude is an automatic, yes, you use automatic transmission fluid. If it's a manual, there's manual transmission fluid. As much as possible, purchase the manufacturer (Honda) branded transmission fluid.

your cluch could be gone!
Why the hell would you want to?
Yes, by removing the manual transmission and installing an automatic. Unless you have a donor car this would be extremely expensive. My advice is that if you want an A/T sell the car you have and then buy one with an automatic.
