Why do I get a range shift inhibited message?

Why do I get a range shift inhibited message?

Failure to detect proper line pressures when a gear range is selected, which may be the result of normal maintenance such as a transmission fluid change having been completed, or the transmission pan was removed for a filter replacement or other type service.

Can a shift be inhibited by the output speed?

Output speed should not inhibit your shift to range – you could be going 100, and shifting to range should put you into the correct range for that output speed. my dads truck is having this same problem, only it happens when in R under load.

Why does my durmax truck say range shift inhibited?

I am hoping someone will have an answer to what is going on with my 2004 GMC Sierra 2500 HD Durmax truck. When I go to shift into gear (reverse or drive) on the dash a message appears “Range Shift Inhibited,” and the truck does not engage into gear. I have to put it back into park and shift into gear again.

Why is my shift inhibited neutral not working?

It could be that you didn’t see the expected turbine speed pull down, or that output speed was too high when range was selected.
