Gear lube is not good for our trans, get that out ASAP. Use Mopar Trans Fluid (Since it's a Mopar Tranny) Some use BG Syncroshift (I do for the moment, probably switch to Mopar fluid next time around), but it's a light oil, not the sludge of gear lube. Get it out switch back to Mopar Fluid and pray nothign was damaged.
