Shifter Locked in Park? Here's a Way to Over-Ride the BTSI Shifter Interlock in an Emergency!
SAFETY WARNING! BE VERY CAREFUL WHEN WORKING ON ANY GEAR SHIFTER ISSUES! MAKE SURE THE VEHICLE CANNOT ROLL BY LOCKING THE PARKING BRAKE AND USING CHOCKS ON THE WHEELS - AT A MINIMUM THE REAR WHEELS SHOULD BE PROPERLY CHOCKED BUT ALL 4 WHEELS CHOCKED IS BEST. WORKING ON A LEVEL PARKING SURFACE IS ALSO CRITICAL!

The original video on the BTSI for Trailblazer, Envoy, Ascender, Rainier was filmed at an angle that did not show the Over-Ride very well at the front of the video. This video may show that procedure somewhat more clearly. Just trying to be helpful. Thanks for watching, and please consider subscribing. Have a GREAT Day!

You may need the assistance of a mechanic trained and experienced with this type of vehicle as It sounds like you could have more than one issue. That said, a shifter mechanism out of sync with the actual transmission can cause a lot of problems due to the signals the vehicle's on board computer is recieving and sending. The key switch will only crank the engine over if the actual transmission itself is in the park or neutral position (a malfunctioning shifter or cable mechanism may cause a difference in the shifter position and the actual transmission position.) I would begin by inspecting the shifter related linkages and mechanisms (ALWAYS STABILIZE THE VEHICLE FIRST). You may have a bad shifter cable issue or - possibly the cheapest to fix and most likely- only the grommet at the end of the cable may be worn/bad/disconnected. You also could have a BTSI issue keeping the shifter locked up, but that is less likely. There are steps on other videos that explain those issues. A first-step easy, cheap fix for that may be to pull the shifter lever boot up and try a bit of WD40 at the points shown in the video. As a diagnostic measure you could drill a hole in the side of the console in the right position (shown on the BTSI video) to manually release the BTSI lock -BUT BE CAREFUL TO ENSURE THE VEHICLE CAN'T ROLL IF YOU MANUALLY OPERATE THE BTSI SOLENOID!

You have the best video of explaintion for this I have ever seen. The measurements being so perfect, let’s just say in thanking you because you saved me Money and Time from getting a Tow.
Glad it was helpful!
Thank you for the video. I waited 3 hours for a tow truck. And nothing. Then I found your video. Had my daughter bring me a drill and tape. Got home and canceled AAA TOW. I SPRAYED SOME WD40 AND IT WORKS FINE. FOUND A FLAT RUBBER PLUG TO COVER THE HOLE AND CALLED IT A DAY. THANKS AGAIN
Glad the video helped! Good reports like yours make it very satisfying to do UA-cam "How To" videos. Thank You!
@cubmancan your welcome and have a blessed day
Thanks you just made my day better with this very helpful video😊
You’re welcome 😊
Thanks, you saved me from areally bad day.i appreciate your help.
Glad to hear it!
Great video!! Thank you. Worked great!!
Glad it helped!
You can depress the button simply by sticking a screw driver into the hole where the shifter boot is, like from where you showed how to lubricate it. If you come in from the passenger side you can see the button from the top down and lever the screwdriver against it. Removing the console or drilling it is unnecessary
Good Point! In any case, proper precautions are absolutely required - SET THE PARKING BRAHE, ETC. It's a bit tricky to do without the hole drilled sometimes, and if concerned with a less mechanically inclined operator, the drilled hole method is ALMOST fool-proof (if it is located correctly). Thanks for the input!
Thank you. You're awesome.
Thanks for watching! Hope it helps you out!
Thank you for this video! I just had that whole section apart so, I'm going to see if I can get to that spot without having to drill into that panel. Thank you very much for the info and the measurements... That really is helpful for me. I'll let toy know how I make out; 2005 gmc envoy.
Glad I could help!
Excelente, me ayudó!
Thank You!
Thank you so much , but I don't made a hole.
I just sersh with a long screwdriver under the plastic decor ,In the same area you mentioned, until I found the bottom and press it , and it's work .
Thanks again.

Thanks for Watching!
So to fix this I would just need to replace the shift interlock solenoid?
Thank you!
You're welcome!

I just took a long screwdriver and pushed it in from the shift boot hole. No need to drill anything.
Thanks for sharing!

Locked Shifter? How To Over-Ride the BTSI Shifter Interlock for Emergency Use! GM Envoy 2002-2008
Extremely helpful information! The photo of it torn down is great too.
Glad it was helpful!
thanks for the explanation but I have another question. Do you why 4x4, stabilititrak an ABS lights are on? Those lights are ON on my envoy and I cant find why.
I don't really have a lot of experience with those warning lights, but have been told that they may be related to the wheel speed sensors. A good code reader may help a lot with that if not done already! Thanks for the comment and watching UA-cam!
Just spent $275 to tow my Envoy home, wish I would have seen this sooner, thanks
Thanks for Sharing Your Experience! Hope you get it fixed okay!
Hello sir, my trailblazer is locked in drive, which should I check first. Thanks so much, excellent videos!
Thanks for the Question: FIRST! Be safe - A vehicle with shifter issues may roll unexpectedly! BLOCK and CHOCK Wheels and SET BRAKES; and be parked on level surfaces!!! If using jacks, properly jack and support the vehicle using substantial jack stands and solid cribbing. Okay, so, SAFELY, determine if your shifter cable is actuating the transmission properly. Usually, there is damage or wear at the transmission end of the cable. (Worn grommets or bent brackets, etc.) Also make sure there is nothing keeping the floor shifter from going through the range of operation, such as debris or objects in the shifter mechanism. Hope this helps and you find your problem quickly!
@@cubmancan problem found! Cable had come off. The 2 piece bushing that goes on both sides and snaps has worn off the edge of the smaller snap in piece. Was able to get it going without calling a tow truck. Now I can replace it since I was able to get it home. Thank you!
Do you have any videos on how to change your neutral safety switch?
I have not done that switch replacement - without looking, I would guess it is on the transmission itself. Let me know what you find out! Thanks for watching!
Thank you for the video. Do you have the link to the other shift lock videos?
Here are a couple more shifter videos, there are also links shared in comments on some of these. Thanks for watching!
@@cubmancan I do not see and other videos, in your message.
I need to push the button to reset and set up my new key fob.
Apparently it works on Isuzus too !!! 😄
Yep. Virtually the same vehicle! Thanks for Watching!
What if it does when you shift it from reverse to drive? Would that have any connection to BTSI ??
By the wiring scheme, the BTSI is strickly a lock mechanism to ensure the brake is engaged when the engine is cranked - should not have anything to do with the engine shutting down. Thanks for watching!
Ok thanks for replying and for making your videos. Trying to figure out why this darn thing is stalling only when I back out of the driveway each morning. Stalls once. Restarts no problem and never dies again until the next morning. Wierd
What is the right fix for locked shifter?
Your tip worked on mine to unlock the shifter, but the indicator in the dash shows R for reverse and it won't engage the starter. I can move the shifter back and forth so long as I don't put it in the Park position. If I do it locks again and I use your unlock tip.
Glad it helped! Sounds like your console shifter will go into Park, but the cable is not pushing the transmission lever all the way into Park position. That can cause a hazard if the vehicle transmission does not lock the transmission in Park. Use the parking brakes lever to ensure your vehicle does not roll when parked in "Park" until you can correct the transmission shifter issue. On the vehicle I worked on the main problem was the grommet at the end of the shift cable worn out - an easy fix, just pry it out and push a new one in (Autozone, etc). AGAIN - WARNING! - stabilize the vehicle when working on the cable and other shifter issues! (Use park brakes, wheel chocks, etc)! Also, sometimes the bracket that holds the end of the cable at the transmission can get worn and loose causing the cable to slide back and forth a bit and not fully engage in Park. In addition, I had to lube up the BTSI solenoid in the console and put some lube at the base of the shifter stick (the linkage there) - used WD40 but silicone lube may be better for the materials involved. Also an electrical issue can occur as the BTSI takes 12 volts to make it operate. Usually the solenoid will work if everything else is in sync. It doesn't sound like the BTSI solenoid is your main problem and I hope you don't have to remove the console to replace the solenoid, as that is quite a job, but can be done. Check everything else out first. Thanks for Watching!
How come it says IZUZU? Are they the same vehicle with a Japanese brand?
They are virtually identical mechanically. GM and Isuzu collaberated on these. Thanks for watching!
What is it moves although doesn't leave parked ?
FIRST! BE SAFE, Set the Brakes and Chock the Wheels before doing any Transmission service!
It is likely a problem with the shifter cable, Most likely the plastic bushings where the cable meets the transmission or a bent bracket from hitting objects with the underside of the vehicle.
Hope it Helps! Thanks for Watching!
How do I get to the other video you mentioned in the beginning of the video??

I did this and now my car won’t start, any ideas?
It worked for the first start, now it’s saying I have no battery and everything works except the starter
Sorry you had trouble with your car. There can be many different causes for the starter not working or working intermittently. The starter motor itself does wear out on most cars and is also a common problem. Wish I could be of more assistance. Thanks for watching!
Kwhy is this car an Isuzu and not a Chevy trailblazers?
Thanks for the question. There were several virtually identical vehicles made by GM for sale by Chevrolet, Buick, Isuzu, GM, and possibly others...Saab Maybe? The shifter mechanisms (and probably 99.9% of all other parts) are the same on all those modeled in the Trailblazer mode. And thanks for watching!
isuzu ???????

What the $%$? Did I just watch? The scientific guesstimations are far beyond me. What you're basically saying is drill hole, poke stick, hope for the best.

Good explanation I tried it but it still doesn't work, what could be issue?
Is the shifter locked in Park? Won't move, even with brake pedal pressed down?
@@cubmancan yes, it's completely lock. Any guess what it could be
