6.0L 2WD in a 4WD setup?

[esee135]

Question, seems like there's a bunch of 6.0L engines with 2WD 4L80E tranny combo's out there. Can the 2WD 4L80E be converted to 4WD and mate to a 4L60E's transfer case? (ie: 6.0L 4L80E swap into a 5.3L 4L60E 4WD). If not, seems like the Toyota Supra 2JZ syndrome, lot's of 2JZGTE motors..all of them mated to automatics..though.

yes, you can have a 6.0L-4l80-4WD, but there are some things that get changed, the trans plug might have to be re-pinned, output shaft on the trans....the SilveradSS guys look to do this as an upgrade but few have acually done it.

output shaft on trans has to be changed and the input shaft on transfer case has to be changed.

I have the exact opposite problem..I have a 4X4 4l80E And I need the 2wd version............wanna swap?

The electronics/wiring harness isn&#39;t the big problem, it&#39;s that a custom input shaft has to be machined from billet for the AWD transfer case to mate it to a 4L80E output shaft (GM never produced one). There is someone in the Syclone/Typhoon crowd that is making these one-off on the side, word is they are ex-pen-sive. Again that is for the AWD transfer case, the 4x4 TC is a different animal, there may well be factory couplers or shafts produced to make this swap.

Also remember that the shallow first gear in the 4L80E is a total performance killer, unless you get the gearset from a motorhome 4L80E.

input shaft for transfer case

there is also this, it is a output shaft that uses the 27 (4l60e) spline count. then there is no need to change the T-case input shaft.
