ResumoSharp transmission resonances have been observed in the $^{235}U(d,pf)^{236}U$ reaction. The shapes of the resonances as well as the angular distributions of the associated fission fragments are analyzed together with the data obtained previously for $^{234}U$. The resonances are interpreted as being hyperdeformed rotational bands with ${\ensuremath{\Elzxh}}^{2}/2\ensuremath{\theta}{\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8}_{\ensuremath{-}0.7}^{+0.5}$ and ${1.6}_{\ensuremath{-}0.4}^{+1.0}\mathrm{keV}$ and $K$ values of 1, 2, and 4 for $^{234}U$ and $^{236}U$, respectively.
