Next time, I say do it yourself. The pump and seals cost about $70. For the 4.0L, it was also a good time to put in a new belt ($15), new plugs ($35) and wires ($50), and coolant ($10). Now that is a lot of good work for only $180 and a couple nights of my time after work.
After I found and fixed my transmission cooler leak, I am now completely leak free which is always a great feeling, especially at 181K miles.
