Car Stuck in Park? HELP!

I'm new to forums needed some help from yall fellas. Here's the low down 2005 Envoy Denali. 58K miles on engine and Tranny. Car runs fine and never had any problems. I was picking someone up today and put the car in park while car was running and then it got stuck in park. By this i mean the actual shifter on the console isn't stuck it goes in all the gears, but its not engaging the transmission. The car starts up fine and just sits in park. Its like a sulenoid or something went out or maybe a piece broke off under neath. Although i have hit anything on the road so I don't know what would cause the car all of a sudden to not engage in gear. The transmission was not slipping or anything before hand. Troubleshooting I tried to pump brake and see if maybe the safety switch or something under the brake was causing the problem but brake lights work and the brakes seem to be engaging. Its like the car's computer isn't telling the tranny or something to go in gear. Any help would be appreciated I got car sitting in parking lot. Don't wanna spend the rediculous fee to tow it.


-Note I also tried putting the shifter nob in neutral, starting car from neutral then moving it into gear but still nothing.

Doesn't sound like safety switch

It doesn't sound like the safety switch to me. If that fails I thought the car would not allow you to shift out of Park. Good luck.

Make sure it's got fluid in the trans?

Cable also could have broken while putting it in Park the last time... Put the E-brake on, ignition on (engine off), and have your wife/gf/friend move the shifter around while you're under the vehicle making sure it's moving the arm on the side of the transmission...

There's a plastic grommet on the cable where it connects to the shift lever
assembly. Most likely, this broke. It may have been broken for awhile,
and just gave way the last time you put it in park.

You might be able to find a replacement grommet in one of the auto parts
chains that carries a variety of "help" items. Otherwise, I think GM only
sells the whole cable...

You might also be able to temporarily rig it together until you can get someplace
to replace it.

Check the diagrams at Compnine.com, and you can see the cable and grommet.

Good Luck!

Chris

I also think it is a malfunctioning cable or something related that it hooks directly to. Someone is going to have to crawl under and see how things look. I hope its a quick easy solution because if it is inside the actual transmission, it intensifies the concern.

I shudder to think in the next decade, automakers will have a shift into gear by wire in addition to throttle by wire.

A couple of other members have had the cable grommet break at the shift lever,
and it did the same thing, so I'm hoping BigTx's problem is the same. It's annoying,
but not drastic.

"Shift by wire"...oh, please, not that!! Talk about creating more ways that things
can go wrong!

Cheers-

Chris

Well thanks for all the reply's I will keep you updated on what it was exactly. Tomorrow I'm gonna lift it in the air and see whats going on with the cable and the actual linkage etc. Note to others I called GM dealer in Houston, Tx . the parts guy told me he's had 10 envoys now this month with the same problem, in fact he told me over the phone he was 100% sure it was the cable that was connected to shift lever and it broke because the plastic grommet went bad. I asked if this was a major problem he said know just oddly enough he's had about 10 in the last month. Now he keeps the entire cable in stock for $74.99. I don't know if thats pricey or not, cause i'm not sure where else to get it. Eitherway I'll have it fixed before Tuesday so I'll let yall know thanks.

Just want to confirm that it was infact the actual cable that has the little plastic grommet that connects the shift lever to under the car. It was broken, don't know how long but problem is fixed. If anyone ever has this problem ya know what to do. Thanks for help guys.
