The automatic Chrysler products in the later years use a "Lifetime" trans fluid which is actually called ATF +4 or ATF AP4 and other names. There is no such thing as "Lifetime" fluid. Trust me! I owned a 1997 Dodge Ram 1500 4X4 and the transmission was the worst part of the entire vehicle. I would at least drop the pan, replace the filter and renew what fluid was lost every 30K.

If your trans has well over 100K and no record of fluid changes, then forget it. Changing it that late may cause more problems.
