You are watching: What does range shift inhibited mean


*

Dear readers,First off, many thanks for having actually me. Ns am a brand-new to the diesel world and the forum. Ns am hoping someone will have an answer to what is going on with my 2004 GMC Sierra 2500 HD Durmax truck. As soon as I go to change into equipment (reverse or drive) top top the dash a message appears "Range transition Inhibited," and also the truck does not engage into gear. I have to put it back into park and shift into equipment again. It then seems to it is in in prefer low gear and also barely moves. Ns then placed it earlier into park, wait a few seconds, then shift back right into gear and also it is fine. Any ideas? Thanks.

after check the NSBU switch examine the linkage. NSBU connecters are an extremely well sealed type the factory. They have actually silcone inside the connector. Lock are an extremely hard come disconnect. You can have bend or kinked transition linkage.

Took my van to the dealership because that them to fix. The is supposedly fixed. The difficulty they say to be the ignition switch within the steering column. They say the the voltage to be misfiring or misreading and not sending out a great signal because that it come enage right into gear. Ns say "supposedly" because I gained a call from the dealer that while check driving the technician rear ended someone, in my truck! So, together you may have figured out, ns am anxious to obtain my truck ago and make certain it is not doing the exact same thing. Will save forum updated. Many thanks again for everyones help.

It appears to be gaining worst i"m wonder if it"s a sensor in the obelisk or somthing v the tranny i have actually to transition back to park then ago to reverse or drive if everyone has any type of tips that"d it is in great
I just had actually this message come up also (LB7) and also I simply washed mine truck. It"s only taken place once before. I"ve had actually recently what I thought were tranny issues, yet now pretty sure it"s electrical? it s okay stuck in 2nd and I have to turn it off, and on a couple of times and also kicks ago into regular mode. Also had a P0716 (input generator sensor), replaced it, but it didn"t fix the problem. Engine light comes on and goes off the next day. Trouble happens around once a week and also now I"m seeing the tendency of as soon as I wash it, appears to happen. To add the roads have been really wet lately, so maybe thats no helping the case either?? can this be the NSBU?
It"s funny, once I obtained this truck, i didn"t listen anything abbout the NSBU switch. Every one of a sudden, that seems choose I hear about people having actually issues since of the rain/snow. I had actually absolutely no worries with mine NSBU switch until yesterday. Haven"t moved the truck in two weeks, but when ns tried yesterday morning, the truck refused to enter reverse.Read my post around my NSBU problem in, ns think, the general board:http://www.yellowcomic.com/forum/g...17-cannot-go-into-reverse-r-light-blinks.html

i"ll shot that however it seemed pretty selaed it"s top top the Driver next right? just making sure i"m feather in the ideal area.
I replaced the NSBU and it maintained coming back. Upon acquisition it to the dealer they replaced the ignition cyclinder b/c they experiment the voltage and also it to be to low and also not sending sufficient to shift. Small confusing, yet my difficulty has to be fixed and have not had actually it take place since. If this doens"t assist let me know, might be able to look up the invoice.

I replaced the NSBU and it preserved coming back. Upon taking it to the dealer they replaced the ignition cyclinder b/c they tested the voltage and it to be to low and not sending sufficient to shift. Little confusing, but my problem has been fixed and also have not had it take place since. If this doens"t aid let me know, might be able to look up the invoice.

I heard others had concern with the ignition switch.. It"s either the NSBU or ignition switch (contacts worn so voltage is erratic).You can shot the NSBU for $40 at napa, then the ig switch.
