In case anyone is interested. I serviced my "lifetime" fluid transmission at 26k miles. My transmission has always had a faint whine most noticeably in 2nd and 5th gears. It sounds like an alternator whining but it is indeed the transmission. Dealers and mechanics have said it is normal as these transmissions have planet gears, which apparently create some whine eventually. (Only going off what I have read and been told). I wanted to see if by servicing the transmission I could get rid of it. Long story short the whine is still there although it is not as noticeable.
A few things...... the JL DOES have a changeable filter. You do not need to change out the entire pan as you would have to on the RAM trucks, chargers, etc. Servicing the transmission is not any harder than any other transmission you may have serviced in the past. There are a few additional steps to fill it or check the level, but it is not really that bad at all. I put in an additional 3/4 quart than what came out. I believe this has probably been low from the factory. There were no metal shavings, etc. in the fluid just the dirty clutch material, the magnets were pretty full with the sludge. The fluid was black coming out. Probably to be expected since new the fluid is clear, but I wasn't expecting it to be as black as it was. I did add lubegard platinum to my fill. It is the only additive I have ever ran in a transmission and is fully compatible with the 8 speed ATF by MOPAR.
For anyone interested here is a video of the process:
