Go to the parts store and look for the Valvoline PS fluid in the white bottle, it says right on the back that it meets Mopar fluid spec MS5931, if you have an Advance nearby their house branded fluid is GTG as well. O'Reilly sells the MasterPro brand of fluid that meets the correct specs also. Any of these options should only run you $5-$6 a quart, vs. whatever inflated price the dealer is wanting to charge you.
There's plenty of threads on here discussing the viability of the options I just mentioned. Do a little searching.
