03 trailblazer stuck in gear

[brian911]

i have an 03 trailblazer. This morning my wife was backing out of the driveway. It appears that it is stuck in reverse. it is an Automatic transmission and it was driving fine in reverse but it will not shift to any other position. I turned it off and now i can not crank it because it is stuck in gear. What do you think my problem is?

Hi, I'm new here and I have the same problem but the shifter stock in park and the underline in the cluster shows that is on reverse. Mine is a 2004 Envoy 4.2L.

Welcome .You may have to crawl under the truck and see if the shift linkage is loose.

There is a little plastic grommet that connects the gear shift assembly to the transmission shifter. It sounds like this little piece of plastic has broken. If you crawl under the car, you should be able to see this with no problem and even put the transmission into park or neutral by hand. Parts + installation at the dealership is about $250 or so.

That's the problem! The plastic grommet was broken. I found the cable for $60 at a GM store. Thanks guys.

Brian911 - I'd love to mark this thread as SOLVED, but did you find the same thing as budaracing? You're the thread starter on this one.

2003 Trailblazer 152K Miles

Issue: Truck was stuck in the parked position despite the shift lever moving when the brake pedal was depressed.

Potential Resolution: Dealer (Dealer Labor), Website (Your labor), Home Depot (Your Labor)

Tools needed: Adjustable wrench, Wire Cutters, Duck tape and Crazy glue.

I was missing the white grommet that goes inside the shift lever.

• Dealer - $92 for the part plus labor = Ridiculous went and actually got the part from the dealer. The little grommet was the only thing that I needed to get fixed, but they only sell the entire cable system.

• Website - http://www.atfspeed.com/store/index....index&cPath=21 Cost = $20. Require you to take the shift lever off and grind out the original pin. If you don’t have a grinder…this is not for you.

• Home depot - $2 + glue and duck tape…I actually only used one washer for 12 cents.

Before attempting any fix make sure you secure the wheels with a brick and use emergency brake.

The breakage:
The Shift Lever Grommet that comes inside of the Shift Cable was broken so the cable popped off the lever. When you move the lever back and forth it will not shift.

If you need to get the lever in to the parked position push it towards the front of the vehicle. I used duck tape and a zip tie to hold it in place until I could get a permanent fix. May last a couple days…Maybe.


Once I got to Home Depot I removed the shift lever

Below is a picture of the lever looks w/out the grommet. I recommend taking this in with you to home depot to make sure your sizes match perfectly.

Once it is off the vehicle you push the hose on to the end of the pin after applying glue to the head and shaft of the pin.


I also put some duck tape around the end to hold it in place and allow the glue to set. I always recommend having duck tape....it's a life saver.

Clip the end off the hose to only allow a ¾ to a ½ inch or so to stick out.

Reattach the shift lever and then attach the cable, add the washer and use the clip to secure the washer on to the hose. Make sure the hose has clearance to move back and forth.

Problem solved for $2
