Oh that kinda changes things. I'd take it to a tranny shop for a drain, flush, filter change, and have the bands adjusted. That should not be expensive and it may help. Just don't take it to Aamco or any other large chain transmission shop, they have quotas to meet and often find more wrong with a transmission than there really is. I would find a small locally owned independent transmission shop that is a member of your local Better Business Bureau and have them perform that service. If you're in SOCAL, I can point you to a known honest Jeep-oriented tranny guy.
