To go to 4Low, do we still have to come to an almost stop to go to 4L in these new shift on fly with the knob on the dash?

Here's what the owners manual says and I included the info for both the manual and electronicc transfer cases but the fast answer is 2 to 3 mph to shift into and out of 4LO.

Shifting Procedure - Manually Shifted Transfer
2H⇔ 4H

Transfer Case Reminder Light

The four-wheel-drive operating light (4WD), located in the instrument cluster, is used to alert the driver that the front axle is fully engaged and all four wheels are driving.

Shifting Procedure - Electronically Shifted

Transfer Case
NOTE: If any of the requirements to select a new transfer case position have not been met, the transfer case will not shift.The indicator light for the previous position will remain ON and the newly selected position indicator light will continue to flash until all the requirements for the selected position have been met. To retry a shift:

return the control knob back to the original position,
make certain all shift requirements have been met, wait
five (5) seconds and try the shift again.

NOTE:

If all the requirements to select a new transfer case position have been met, the current position indicator light will turn OFF, the selected position indicator light will flash until the transfer case completes the shift. When the shift is complete, the indicator light for the

selected position will stop flashing and remain ON.
2WD⇔ 4HI

Rotate the 4WD Control Switch to the desired position.

Shifts between 2WD and 4HI can be done with the vehicle stopped or in motion. With the vehicle in motion, the transfer case will engage / disengage faster if you momentarily release the accelerator pedal after turning the control switch. If the vehicle is stopped, the ignition key must be in the ON position with the engine either RUNNING or OFF. This shift cannot be completed if the key is in the accessory position.
NOTE: The 4x4 system will not allow shifts between 2WD/4HI if the front and/or rear wheels are spinning (no traction). In this situation the selected position indicator light will flash and the original position indicator light will remain ON. At this time, reduce speed and stop

spinning the wheels to complete the shift.

2WD or 4HI⇔ 4LO
NOTE: When shifting into or out of 4LO some gear noise may be heard. This noise is normal and is not detrimental to the vehicle or occupants. Shifting can be performed with the vehicle rolling 2 to 3

mph (3 to 5 km/h) or completely stopped. USE EITHER

OF THE FOLLOWING PROCEDURES:

Preferred Procedure

1. With engine RUNNING, slow vehicle to 2 to 3 mph (3to 5 km/h).
2. Shift the transmission into NEUTRAL (depress clutch on manual transmissions).

3. While still rolling, rotate the transfer case control

switch to the desired position.

4. After the desired position indicator light is ON (not
flashing), shift transmission back into gear (release clutch
on manual transmissions).

Alternate Procedure

1. Bring the vehicle to complete stop.
2. With the key ON and the engine either OFF or RUNNING, shift the transmission into NEUTRAL (depress clutch on manual transmissions).
3. Rotate the transfer case control switch to the desired position.
4. After the desired position indicator light is ON (not flashing), shift transmission back into gear (release clutch

on manual transmissions).

NOTE: If steps 1 or 2 of either the Preferred or Alternate Procedure are not satisfied prior to attempting the shift then the desired position indicator light will flash continuously while the original position indicator light is ON, until all requirements have been met.

NOTE: The ignition key must be ON for a shift to take place and for the position indicator lights to be operable. If the key is not ON then the shift will not take place and no position indicator lights will be on or flashing.

That's what I thought. Thanks
