what type of automattic trany will replace the 3 on the tree with zero modifications besides cutting a hole in the floor in my 64 chevy c10?
Most likely a 2 speed Powerglide. If you can get a sales brochure for your truck that will tell you if the Powerglide was an available option. Try eBay or Faxon Automobile Literature in Riverside, California for the sales brochure. A factory shop manual or repair manual for your truck will tell you also. HTH. -Jim
