What does the m stand for on my shift column - 2005 GMC Sierra 2500HD 4WD

Is this console shift or column shift? If column shift, I'd have to look under the hood or under the vehicle at the shift linkages to see if the linkages are moving? Is this fwd or rwd, I haven't looked up any info on your vehicle?
If column shift and the shift linkages don't move, the shifter in the column may be broken, if that is the case, I swap out the steering column for one with a good shifter.
I don't know your model year? If the ignition switch is on the steering column, I don't know if it might effect your security system, where applicable? You might be swapping one problem for another, hope not? Something to think about.

Is it column shift or console shift? If it is column shift, the switch is on the top of the column, you have to drop down the column and is adjustable by the mounting bolts. If it is in the console you have to remove the console housing to get to it.

if the shift process is through a cable then check the cable for wear and fraying, rust or dry. If it is through linkage check for worn /rusted /tight connections

At the end of the steering column, under the dash is a steel bracket that the inner portion of the shift cable is attached to. There are two t30 torx bolts affixing this bracket to the shift tube in the steering column. These bolts commonly come loose. You will have to stand on your head under the dash, but tightening these two bolts will solve your problem.

I did'nt know if you had a FLOOR SHIFT , COLUMN SHIFT EXPORT OR COLUMN SHIFT
So here is the most common....the COLUMN SHIFT....

It sounds like the shift tube bushings are worn out. There are usually 2 u shaped clamps that have nylon bushings that hold the shift tube to the steering clumn. If loose, that throws off the shift position, could be btween 2 gears at once, and throws off the park - neutral safety switch. Fix that first.

Very likely you have a loose connection on your transmission shift linkage, or you have a shift cable that is no longer tight.

First jack up the vehicle and secure with a jack stand. Check the connection on the drivers side of the transmission to make sure it is connected tight. There should be a nut holding the shift lever in place. If it is correctly fastened, remove the steering column plastic covers by unscrewing screws and check for loose connections.

Depending on whether it is a column shift or floor, you have to get the linkage loose enough to get the car in neutral, move the selector back to the proper setting, and tighten everything up.

If the car is not setting on a hill or incline, you should be able to move the shift levers by hand when you've loosened the linkage and move it until it is in neutral. Put on jack stands and chock the wheels that are on the ground.

You may have a loose shift linkage in the steering column. Remove the upper and lower plastic covers behind the steerong wheel (5 or 6 philips head) and see if you have any loose torx head or allen head screws. Ea
rlier models had this isue.
