I have a 2000 TJ with 116,000 miles on it. It just went in the shop today because the transmission has been slipping...

I'm hoping it's nothing serious... If it is... I've been thinking of getting a V8 and new tranny installed... Any ideas what this may cost? And what shops in Phoenix could do the work? COP4x4 only works on JK's. Also should I get the Dana 44's front and rear done at the same time?

Or, should I wait until next year to get a 2012 JK with "hopefully" the new V6 that has more HP? The one thing that has prevented me from buying a JK is the week engine... I dont want to buy a new Jeep then spend 20K on a HEMI upgrade....

You can see some pics of my Jeep here.

You might be better off waiting for the new JK.

I think all of the custom install shops like COP charge about the same for a TJ Hemi as a JK Hemi.

I have a LJ with a 5.2 Magnum in it and a JK with a 7.0 Hemi in it and they both have their pluses and minuses as far as the Jeep itself goes and the type of wheelin you do with it. The JK is much more street friendly and the LJ is more tight trail friendly. I love them both. I do wish I had more power in the LJ though. The JK has me spoiled with power. Both have 60's with 5.38's. JK is on 38's and LJ is on 40's.

Bottom line is without spending a ton of money on a Hemi swap you need to wait for a better engine than what is currently available to us here in the states to come in a JK from the factory.

 

Well, now that Chrysler has confirmed the JK will be getting the new engine next year. I will be a JK owner in less than a year!

 

What engine, and how much more power? I know the TJs were constantly improved over the model years, but from one year to the next I never saw such an amazing improvement that I wouldn't buy an older one.
