There is a transformation which reduces almost every diffusion process to an arithmetical Brownian Motion or to the Geometrical Brownian Motion (the original Black-Scholes-Merton model). Details of this transformation can be found in my paper "The Analysis of Deltas, State Prices and VAR: A New Approach" downloadable from http://pluto.mscc.huji.ac.il/~mswiener/research/research.htm This is not a simple way, but it is very general and there are some examples in the paper as well.
