  We present a new measurement of the tau neutrino helicity, hnu and the tau
Michel parameters rho, eta, xi and the product delta xi. The analysis exploits
the highly polarized SLC electron beam to extract these quantities directly
from a measurement of the tau decay spectra, using the 1993-1995 SLD data
sample of 4328 e+e- --> Z0 --> tau+tau- events. From the decays tau --> pi
nu(tau) and tau --> rho nu(tau) we obtain a combined value
hnu=-0.93+/-0.10+/-0.04. The leptonic decay channels yield combined values of
rho=0.72+/-0.09+/-0.03, xi=1.05+/-0.35+/-0.04 and delta xi=0.88+/-0.27+/-0.04.
