I've noticed that even though my expy is in 2H, I've seen on the dash that it says 4x4 shift is happening (can't remember the wording) and to pull forward. Seen it happen at highway speed a few times, and it's been dry.
I've not noticed any change in the drivability, or any feeling of shifting happening.
Now I had been using 4H, anytime it's been raining, then after a few days of dry, and running on 2H, I don't see the message. I've not had this long enough to investigate but I'm gonna start logging it and what the conditions are.
The message can come up due to the shift motor binding. Why are you using 4H in rain? That's a good way to destroy some parts. Does yours have 4A? Or is it just 2H , 4HI and 4LO?
Oops. I meant 4A. I haven't used either H or L yet.
Like right now, I started it, and it says "shift delayed, pull forward". I haven't changed anything. I drive it to work 5 miles in 2H. It's sat for several hours.
I would run the transfercase through all ranges and see if it goes away. When you are shift from 4A to 2Hi are you moving? This is a ESOF so if you do try to shift out of high range the system may not disengage as it binds.
My understanding (and I could be wrong) is that moving the selector switch between A4WD and 2H does not shift anything. It just changes the electronic clutch strategy in the transfer case from variable (based on wheel speed) to 100% applied.
I'm moving when I switch either way. Or I have normally. If I come out to the truck and it's raining, I'm sure I've switched to 4A before moving.
When I left for work a few hours ago, it came up with the switching 4x4 message again before I even moved, and I've not switched it recently.
I'm not sure when I'll get around to disconnecting the battery cable. My work schedule right now leaves me little time to do much on it, unless I'm in it at work during breaks.
Will I lose all my setups in Sync and the radio? I just finally got it all setup. Took a few days to get the free trial of Sirius going because they had a different radio ESN in their computer for my VIN.
Update time: I have not disconnected the battery yet. Maybe today.
I almost always leave it in 2H.
Many times after starting the truck, and going into g
Drive, and sometimes even after just stopping at a traffic light, I get the messages, "Shift delayed. Pull forward" and "4X4 shift in progress". I'm not changing the 4wd selector at all. I'm in 2H.
I've noticed sometimes when it does that, if I'm turning in my driveway, it feels like it's binding. No sounds though.
So I tried to go into 4L. It said to put it in neutral. I did. Then it says pull forward. I did. Then says to put in neutral. Back to pull forward. Over and over. It did not go into 4L. Sped up and it says I gotta be below 3 mph.
I thought it wouldn't go into 4H but it did after a few tries.
I need to check my extended powertrain warranty but I bet it won't cover it unless there's actually a bad transfer case, and I'm guess this is some kind of sensor or misadjustment.
Here's a video of me going thru the different settings and what my truck does. It went into 4L but it seemed the same as 4H. Until I get some ice or snow I won't know if it's really in either.
I've cross posted to the 4x4 forum too but no real answer yet.
Just played with it again. I never get an error. It too a few minutes but it claimed to be in 4L but watching the tach and speed, it was the same as 4H.
However I'm pretty sure it went into 4H cause I was on a heavily salted parking lot and floored it, and it didn't spin like it did in 2H and 4A.
If it's not getting to 4L, I don't understand why I don't get an error. I'll read the codes tomorrow but there's nothing on the dash about getting a code.
If it was the transfer case actuator motor, I would think it either works or doesn't work. It does work as it does go into modes other that 4L. If it were the position sensor, it would never be satisfied it's in 4L. Confusing.
