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

 

[FrkyMnky1487]

Take your pick. There are guys running the stock 4L60e, 350 or 400, and the 700r4. There are even guys running a nv4500, nv3550, and granny gear 4 spds. Its pretty much dependent upon what you want to do.

my question is.. I have a donor 2001 Silverado that I am going to use the 5.3 out of. Just wondering if the 4l60e and stock case (not even sure what that one is) would hold up. If so I would like to use that bc I have a DSD J10 axle

1981 CJ-7, 5.3L - th400 - dana 300

would the stock tcase hold for a while (maybe a year.. tops) until I threw in an atlas?

1997 TJ - 5.3l, TH350, Atlas 4.3.

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.

it really depends on what your doing and what the rest of the driveline is, but ive seen some chevy trucks get badly abused and stay together, so i dont know why you would have a problem with it for a little while, i would run it, whats the worst that could happen? you break it and then you just order your atlas.

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...

how many of you are running a stock TJ pump?
If not what pump are you running?
Also what axle gears are you running?

I have a 5.3 39.5's and 4.10's and it seems to have no sack, about to pull the trigger on 5.13's. Figured i'd ask

 

[jeepmaniac04]

What wiring harnesses are you guys running? I putting a 5.3 with a 4L60E and dana 300 in a 1947 Willys with 35's and 4.56 gears.

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.
