Tranny swap 6spd to Auto. Worth it?

I really would like to swap out my 6spd for an auto. My last TJ had an auto and it was so much nicer to drive. ANy links you guys could give me or advice on the swap would be helpful. Thanks

Your 01 had an 32RH and was a 3 speed. If you're planing on swapping 42RLE in place of your 6 Speed NSG370 you might want to do some reading into it. Unless your LJ has a front axle that can be geared deeper than 4.88 it would be undergeared for your 35" tires. Youre better off keeping your NSG370.

Some people like automatic transmissions, some like manual transmissions.

Who knows, you may change your mind as years go by?...

the 05-06 NSG370 tranny is made by Mercedes (parts are a nightmare) and the 42LRE has a steep overdrive ratio.

Both have their faults but there are threads out there about swaps being done

I just feel like I am constantly shifting with this thing. I have only owned 4 Autos out of 40+ Vehicles. Maybe In getting old and lazy?

Ok before I make any sudden moves, I need to lose this awful TC drop. Will a SYE kit do it , do I also need a longer Drive shaft. I have a 2" BL and unsure if there is a MML in this thing. I looked and it doesn't seem like it. I would like to do a flat skid but would be happy with the current where it originally was. Looks so pathetic how it is. Thanks.

I'd trade you my auto for your 6 speed setup. It's too bad you're so far

A SYE and a double cardan (commonly incorrectly called a CV) drive shaft should take care of the vibes so you can remove the TC drop. You will however need upper and lower adjustable control arms, an angled rear track bar bracket and probably a couple other things I'm missing. You will likely have to do someting with the lower shock mounts or coil buckets as well since rotating the axle may cause the shocks to hit the coil bucket.

You could do a search and get numerous threads that go into detail on this. Here are a couple to start.

As somebody with a 42RLE with 137k miles on it and no real issues I do believe the suckiness of it gets a bit exaggerated but if I were doing this I'd really try to find a way to make an AW4 work. Have that in my XJ and the combo with 4.0 seems worlds apart from the 4.0/42RLE combo.

Had trouble with reverse in a 05 TJ with 42RLE at 91k miles...didn't like it.
