2012 shifter won’t move into Manual position

[gotatahoe]

Hi all: The shifter in my 2012 won’t go into the M position. It feels like it hits a hard stop. Pulling the lever forward doesn’t make a difference. The lever moves from P through D fine and the transmission seems to work OK.

This happened following a transmission rebuild and they replaced both shift cables. Clearly they did something wrong, but I don’t live close to that shop so I’d rather not take it back if it’s something I can easily fix myself.

From searching on the internet I see that this happens often, but couldn’t find an example of someone fixing it.

The search on this site didn’t yield any hits at all.

Has anybody fixed this? Any clues where to look? I’ve looked inside the lower dash area and don’t see anything obviously out of whack, but I don’t necessarily know what I’m looking for.

My thoughts are.. pop the shifter cable off at the transmission..

See if you can rotate the crankarm to M by hand underneath vehicle..

Then see if you can move the lever far enough that would normally put it into M.. (take note of shift lever position in D first)

One of those two tests *should* show a problem?

That makes sense. It will be a couple days before circumstances align for me to crawl under there, but I will try that.

take it back to the shop that did the work and request they adjust the shift cable. just show the tech or whoever is at the counter what is going on. they should have you in & out in no time.

Update I have the same problem.

I wonder if the cables stretch and get out of adjustment?
Although in the OP's case, it sounds like he had two new cables....

Here are adjustment instructions...
