I'm pretty sure that the 2002 still has the 47RE transmission. If so, the filter and gasket from earlier 47RE's would work. FWIW, Dodge has the best gasket that I have seen. It's made of plastic with a dual rubber ring mated to both sides. Doesn't leak at all and can be reused in a pinch. Use the older 727 transmission filter instead of the newer metal ones. The transmission guru's on this site like them better and I think they are cheaper.
