Changed my transmission oil today at close to 24,000 miles and it didn't look that bad. Bought 4 qts from the local Dodge dealer and installed close to 4 qts. Shifts alot better now and the only conclusion I can come up why it was a little bit hard to shift was the factory didn't put enought fluid in at the factory. You guys that are having a little problem when shifting check your transmission oil and see if you have enought fluid.
