Anyone have any experience? My '06 3.9L has decided that the front seal wants to leak oil, at a pretty decent leak. I was quoted $800 to get it fixed at the dealer, plus another $300 for the transmission cooler lines and transmission pan gasket (which are also leaking but nowhere near as bad).

Anyone ever do this on one of these cars where everything is a pain to get to? I could save myself a good chunk of cash but those leaks are not very easy to get to (other then the pan gasket).
