  Background: Multi-nucleon transfer reactions have recently attracted
attention as a possible path to the synthesis of new neutron-rich heavy nuclei.
  Purpose: We study transfer reactions involving massive nuclei with the
intention of understanding if the semi-classical model GRAZING coupled to an
evaporation and fission competition model can satisfactory reproduce
experimental data on transfer reactions in which fission plays a role.
  Methods: We have taken the computer code GRAZING and have added fission
competition to it (GRAZING-F) using our current understanding of
$\Gamma_n/\Gamma_f$, fission barriers and level densities.
  Results: The code GRAZING-F seems to satisfactory reproduce experimental data
for $+1p$, $+2p$ and $+3p$ transfers, but has limitations in reproducing
measurements of larger above-target and below-target transfers. Nonetheless, we
use GRAZING-F to estimate production rates of neutron-rich $N=126$ nuclei,
actinides and transactinides.
  Conclusions: The GRAZING code, with appropriate modifications to account for
fission decay as well as neutron emission by excited primary fragments, does
not predict large cross sections for multi-nucleon transfer reactions leading
to neutron-rich transactinide nuclei, but predicts opportunities to produce new
neutron-rich actinide isotopes.
