A series 81 transmission is identical to a Series 80 transmission. And a 1929 transmission internally looks very much the same: straight cut gears, no beveled gears or Herringbone gears.

As far as I know the Herringbone gear transmission did not get used in Pierces until 1930 in the model A and B cars. The Model C 1930 cars still had the ’29 transmission, straight cut gears and a driveshaft drum parking brake.

The ’29 transmission had the parking brake on a drum on the output hub of the transmission, an external contracting band was the parking brake. The Series 80 and 81 parking brake was by actuating the rear drum brakes via the brake handle.
