Hi Chet:
These problems with the port transmissions were resolved with updates through the 1970's with the last update being 1979 from Allison.  This problem only existed when combined with the 8V71TI engines.  If you are purchasing the 45 with the 8V71N engines, this problem is not applicable. Essentially the problem was lube oil was not getting to the top bearings of the unit in sufficient quantities with the higher powered  TI engines.  Many of these transmissions went "ouch" during the '70's until finally resolved.  I recently delivered a 1981 42' Bertram Convertible with 6V92TA engines which were identical in power to the 8V71TI engines.  The only problem here was that engine surveyor found that the flywheel oil seal was leaking internally on one of them because of age, and wear and tear.  Be absolutely sure that this is looked at by the engine surveyor.  This repair could cost anywhere from $2500 to $5000 per transmission.
Good luck and best regards,

Jim Rivas
