Unable to Engage 4wd Low

[akhil.g]

I own a Ram Big Horn 2020. I'm unable to shift to 4wd low. but I'm able to select 4wd H and 4wd auto. when i turn on the truck and select 4wd auto, it will blink for few seconds, and it will show 4wd shift cancelled.

I've never had this issue with either of my Rams, but I had it with one of my Chevys. The electric solenoid/motor that shifts the gears in the transfer case had burned up. If my Ram gave me this issue, that's where I would start based on my past experience.

However, I'm sure someone with more knowledge on Ram 4wd systems can point you in a good direction!

When Trying to go into 4-low are you stopped with transmission in neutral?

i tried everything. In neutral, P & D. Does resetting by removing battery works?

When you tried it in park and drive the computer probably said...oh no, shut him down.

To go into 4 low you should be in neutral coasting under 5 mph. You can also just be in neutral, but a slight roll is best.

You could try unhooking your battery. It may then let you try.

Transmission neutral, slow coast select 4wd Low.

A few months ago I couldn't shift to 4H, 4L, or 4A.

I bought swapped this out and it fixed the problem. Be sure to clean out the electrical connector (mine was covered in oil from the previous owners dealer oil changes).

For $100 and ten minutes, I did that vs a trip to the dealer (or two) and my $200 MaxCare deductible.

Having a similar issue on my 2019 Laramie, no 4h, 4l, or 4auto. Swapped out both the front diff actuator and the xfer case shift motor. Still get the shift not complete message. Just get a clicking sound. I'd liken it to the same sound you'd hear with a dead battery and the starter solenoid. Any thoughts on next steps? Thanks.

I'm having a similar problem. Did you get yours fixed?
