Yes ,regardless of which seal is used as you have to loosen main bearings so the crank can be moved down as the seals are crush type and you wont have the clearance to fit the new one,Split seals (2 piece)are the easiest to fit without moving the crank too much.The one piece seal also means trans removal.As far as removing trans completely you may be able to move it back while its being held up by a trolley jack and only pull it back far enough to give you the clearance needed.Autos are far easier than manuals.If its the rope type seal a special tool is used to fit them and its not a tool that is sold just anywhere as that type of seal kept noahs ark from sinking and havnt been used in engines for many many years.

To replace the seal, the mechanic will have to either lift the engine or lower the transmission. You will get much better pricing going to a transmission shop (e.g. AAMCO) and getting a quote from them to replace the seal.

i had the same problem and it turned out to be the gasket on the rear main seal housing not the rear main seal.
