2004 TJ Transmission and Transfer Case Swap/Upgrade
I'm new here and hoping I can get some help. I recently bought an '04 Wrangler Rubicon with a 4.0L and a 5-speed. I was thinking of changing it to an automatic transmission to make it easier to drive daily. The transfer case is making strange noises and vibrates now when I engage 4wd, so I'm guessing I should go ahead and upgrade sooner instead of later.
My question is about what's the best setup to upgrade to? I'm wondering if a trans/transfer case combo from something newer might be better. I'm thinking a newer setup might have more gears in the trans to help with fuel mileage.
I forgot to mention the Jeep has a Rubicon Express long arm lift and 37" tires with 4.88 gears. I'm hoping someone has done this swap and might be willing to share their knowledge with a newbie.
