Transmission maintenance strategy for longevity

I own a 2011 JGC Limited,. Bought new now has 95K miles now.
Always serviced, no tick, Beautiful Jeep!
My goal is to keep it to 150K ++.
My trans has never been touched, fluid pink, no smell. Sometimes clunks putting when manual shifting between gears.(P R N D).
I am way over any service interval on the trans. It is w5a580 Trans mission.
Here is the advice opinions I am seeking;
1.- Have pan dropped, change filters and add any fluid about 4 qts. BG fluid. $190 by my trusted Mechanic.
or
2- Flush trans. No new filters, add MoPar 4+. $350 by Dealer.
or
3- Have pan dropped, change filters and add any fluid about 4 qts. $250 by Trans. Shop
or
4. Have pan dropped, change filters and add any fluid about 4 qts Aamco fluid by Aamco. $243.
or
5. Just leave it be. you think?
Can't wait to hear your opinions or comments.
Thank you,
Steve

 

I'd recommend a drain/fill/filter and no flush. Use Mopar 4+ or OEM specified ATF

 

Thank you, that's what I will do.

 

The dealer option is to CAUSE problems so they can ding you for a new trans. NEVER let anyone flush your tranny.

If you can find a shop that will recover your old fluid and put it back in after dropping the pan and replacing the filter, that is best option with 95k miles and no previous service.
