    Transmission serviced at 65K and 140K miles with no issues or metal.

    It started at 162K, leaked a small amount for about 4 days, then stopped (for a month till yesterday). It appears to be coming from front seal. Parking flat, it drips right about where engine and transmission meet. Parking downhill in my driveway, it drips off skid plate area. Was a couple tablespoons overnight when it first started. Yesterday, there was probably 1/4 cup under the truck after work, and a little less than that overnight.

    Should I try some Lucas stop leak, Have my shop drop the tranny and replace the seal ($1000)? Shop wants $5000 for a new Jasper with 3 year warranty, but that seems really high. Not sure what the stop leak would do to the shifting. It has always performed well and both services had it looking new inside. My thought is get the new seal, but that can be a little iffy for fixing it. What would everyone else do?
