If I recall, they recommend nothing other than Castrol Syntorq for the
manual trannys (well DC only recommends their fluid, which I have heard is
repackaged Syntorq) I also belive the 5-speeds take an oil that's closer to
10w-30 than 75w-90
My recommendation is to get the Mopar fluid (just to be safe) and change it
out ASAP
