Will "stop leak" work on a small leak in the Gear Box?

The leak is very minor and doesn't appear to be coming from the bolts. Over 3 months it has leaked about half a quart. Just wondering what my options are because the Jiffy Lube guy said it will cost me over $1K to have the dealer take it apart and check it out.

Anyone have other suggestions aside from stop leak?

Update:

Add: This is a 2004 Lexus GS300 with 45K miles. I purchased it 5 months ago with 40K miles, and had it inspected at the Lexus dealership before purchase without any problems.

Update 2:

I'm open to any/all suggestions. Or is there no other way besides having a mechanic take it appart?

    You do mean transmission stop leak, don't you...I've not had good results with those really, but you could try...the real answer is that it may be a small leak now, but it is only going to get worse over time.

    First of all, don't ask for or take advice from any Jiffy Lube employees, ever! If you're concerned about a leak, take it to a real mechanic (doesn't have to be the dealership). Without more vehicle information, it's very difficult to make the proper suggestions.

    As another poster said, NEVER listen to advice from a Jiffy Lube "technician." Had one try to tell my son he needed ball joints, tie rods, and idler arms for his truck (told us they could do it for $700.00 bucks), jacked the vehicle up myself and found one bad tie rod. Replaced it myself at the cost of parts. As far as your transmission, it could be a seal leak or it could be the gasket. Take it to a reliable service center to be sure.
