We calculate the transition form factors of the semileptonic $B_c\rightarrow\chi_{c2} l \bar{\nu} $ in the framework of QCD sum rules taking into accountthe two-gluon condensate corrections. Using the obtained results of formfactors we estimate the decay widths and branching ratios related to thistransition at all lepton channels. A comparison of the obtained results withthe predictions of other non-perturbative approaches are also made. The ordersof branching ratios for different lepton channels indicate that the$B_c\rightarrow \chi_{c2} l \bar{\nu} $ transition can be studied at LHC usingthe collected or future data.
