Hey all you guys that are running the 5.3l chevy motors in your Jeeps, what trans and case are you all running?

You could use the 4L60E if you need OD, or a 700R4. Both are expensive to build, but the 4L60E needs computer control, which can add that much more complication. 700R4 will be easier, TH350 or 400 is easiest & cheaper.

I'm running the 5.3 with 4l60 and stock pushbutton 4x4 transfercase out of a 2002 avalanche it works fine but i wouldn't put it in to much of a bind or it lets the chain slip. I think im going to change to the np 241 or 231 with sye just to get by until i can get a good case. Also wanted to say im running dana 60's and 41 inch swampers . I havn't broke the stock case in a year of abuse.
One question for the guys with the 4l60 and the atlas. Are you running the speed sensor after all your gear reduction or in 4 lo does it think its going 100 miles per hour at 35 ?

CJ - 5.3/4L60E/Dana 300
The VSS is located on the adapter, prior to the t-case. Low range throws the speedo off by the same factor as my gear reduction.

What kind of HP & torque numbers are you expecting with the LS6 intake & cam? I could always use more power out of my 5.3...
I'm running the factory yj 2.5 liter fuel pump seems to work fine . I also went with 5.38 gears and 41's it has plenty of power . I can't fully test it yet since ive got xj springs on the rear . I get serious axle wrap when i hammer it. Getting 4 linked as we speak.
1992 YJ 2002 5.3L vortec - 4L60e - Stak4speed transfer case.

5.3,sm465,np205
I built a truck for a kid here with a 5.3,Advance adapters clutch kit,sm465, and np205.I used a painless harness, and had the computer reflashed by fastchips.They claim 375 rear wheel horsepower and it feels like it the truck rips.Oh, it is all in a 72 chevy 4x4 fleetside,painted hugger orange.:smokin:

In the middle of this swap now!
I can't offer much yet b/c I'm right in the middle of this swap as we speak. I have a 5.3 Vortec LM7 from a 2002 Avalanche, a 4L60E from a 2002 Suburban, and decided to go w/ a NP241C from a 95 Tahoe along w/ a JB Conversions super short SYE kit. It's going to be stuffed into a 95 YJ that came stock w/ the 2.5 Liter piece of crap engine and AX5 manual tranny--probably in about 2 weeks.

I am in the process of building a 5.3 for the CJ8. Its a 2003 with full floating rods and the newer pistons (anodized top ring land, nitrided top ring, and floating pin). Its going to be running a LS6 Zo6 cam with milled 5.3l heads. The trans is a built th-350 with the trans go manual kit. More to come as it is installed and tuned.
Where is everyone going for harnesses? I am thinking of just calling painless and dumping the 700 bones.

We just gutted a tj at the shop and its ready for a 5.3 nv4500 and a built 231. The customer wants headers and i recommended stainless. Does anyone know who offers stainless headers that will fit?
