We consider the contributions of new gauge bosons to W{bar t}b coupling in the top-color-assisted multiscale technicolor model. We find that the exchange of the diagonal extended technicolor (ETC) gauge boson has no contribution to W{bar t}b coupling. Using the CERN LEP value of R{sub b}, we calculate the corrections to the CKM matrix element V{sub tb} which arise from the sideways ETC gauge boson and coloron exchange. We find that the {delta}V{sub tb} is significantly large for a certain range of the parameters which might be detected in the Fermilab Tevatron collider{close_quote}s run 3. {copyright} {ital 1997} {ital The American Physical Society}
