  With the discovery of strong coupling physics and superconductivity in
Moir\'e superlattices, it's essential to have an understanding of strong
coupling driven superconductivity in systems with trigonal symmetry. The
simplest lattice model with trigonal symmetry is the triangular lattice Hubbard
model. Although the triangular lattice spin model is a heavily studied model in
the context of frustration, studies of the hole-doped triangular lattice
Hubbard model are rare. Here we use density matrix renormalization group (DMRG)
to investigate the domininant superconducting channels in the hole-doped
triangular lattice Hubbard model over a range of repulsive interaction
strengths. We find a clear transition from $p$-wave superconductivity at
moderate on-site repulsion strength ($U/t = 2$) at filling above 1/4 ($n \sim
0.65$) to $d$-wave superconductivity at strong on-site repulsion strength ($U/t
= 10$) at filling below 1/4 ($n \sim 0.4$). The unusual tunability that Moir\'e
superlattices offer in controlling $U/t$ would open up the opportunity to
realize this transition between $d$-wave and $p$-wave superconductivity.
