In the present paper, we investigate some exact cosmological models in gravity theory. We have considered the arbitrary function 
where 
is an arbitrary constant, 
are respectively, the Ricci-scalar curvature and the torsion. We have solved the field equations in a flat FLRW spacetime manifold for Hubble parameter and using the MCMC analysis, we have estimated the best fit values of model parameters with 
regions, for two observational datasets like H(z) and Pantheon SNe Ia datasets. Using these best fit values of model parameters, we have done the result analysis and discussion of the model. We have found a transit phase decelerating-accelerating universe model with transition redshifts 
. The effective dark energy equation of state varies as 
and the present age of the universe is found as 
Gyrs, respectively for two datasets.
