Shifter Mounting Bolt Stripped

110 Views 8 Replies 2 Participants Last post by  merlinj79
I was changing to a short shifter, and I believe one of the bolts snapped. The bolt was stuck when i was loosening it and i forced it and it now freely spins and doesn’t tighten or loosen. It also freely moves up and down but won’t come out as shown in the video. I’ve tried applying leverage with a flathead while loosening with a drill but no luck. Anyone know where the bolts screw into on the bottom of the chassis/have any other ideas on how to get it out? Car is a MT 06

That doesn't seem like a stripped bolt or hole, seems more like a nut is loose underneath. Cage nut, threaded insert or the like.

The shop manual shows the bolts clearly, and the holes they go into. From the diagram, I'd guess the holes are just tapped holes, no sign of cage nuts. But that's not for sure, they might have not bothered with that level of detail.

Have you removed any of the other bolts? Look at the ends, any sign of corrosion? That might indicate that the holes are open at the bottom.

I'd probably jack the car and get under there to see if you can access the holes and learn more. Or go to a junkyard and see if there's a car with the shifter removed... I'd guess an Accord would have the same holes but not certain.

Also if there's a threaded insert under there the bolt might actually be completely loose and able to be removed at this point, it just might be held down by the shifter housing. If you can get the other three bolts out the whole thing might just lift up. I'd probably try that, but carefully. If that's the case and it just pulled out the insert, you can probably replace the insert or maybe JB weld it back (anti-seize the bolt and tighten it gently).

Here's a video for an 03 accord automatic, they probably use the same mounting system on all accord/TSX bodies. It looks like the bolt holes might have an insert.

the bolt is rusty but through the hole i can see metal so i’m not sure what exactly is under it, idk if there’s another layer or something else. Also the max height of the stuck bolt that i can pull is way lower than the height of other bolts. the threads are rusty maybe part of it got stripped?

i just tried lifting it out and no luck
Can you tell if that other hole has a press-fit threaded insert, or if it's just drilled and tapped?

The way the bolt is so loose is not typical of a stripped bolt in my experience.

If it's an insert that got twisted out, you might be able to gently hammer it back in. If that works, try some penetrating oil overnight to get the bolt out. Then turn the bolt back and forth while you unscrew it.

i believe it’s an insert, the top layer is thin metal and then under the larger thin hole is the threaded hole. i’m not sure. the mounting holes look like this. it’s hard to get a picture of the actual ones, but they look the same as this one.

Hard to tell. could be an insert.

I don't think it will hurt it to gently try to tap it back in place.
