2023 Transfercase modification

[zstroken]

I had read about 4th gen mods for the Tcase, to engage the clutch via hardwire. Anyone selling this wiring harness that includes this modification?

What would doing this accomplish?

The Laramie trims and above, are equipped with automatic 4wd. There's a clutch inside the T/C which is switched in and out by the electronics, so there's no 4wd until the controls detect wheelspin. The 4th gen Rams had someone fabricate a bypass circuit to be able to energize the T/C clutch manually. This circuit eliminates fault codes resulting from the 4wd controller detecting clutch engagement when it is not commanded to engage. Last time I looked, no bypass circuit for the 5th gen DT yet.

In short there's no such thing as 4 lock, the electronic controls prevent it.

My laramie has a 4wd auto position or button, can't remember which, and a 4wd position. If auto lets the computer control that clutch, what does 4wd do?

 

[N7GZN]

4wd only when the controls engage the T/C clutch electrically when it determines that there's slippage..AND wheelspin at the rear axle which engages the T/C clutch mechanically. These two elements have to be in place for 4wd to be engaged.
Some folks have removed the auto T/C and installed the T/C out of a Rebel, it can be done, then one would have 4 lock.
