Default Shift **** thread pitch adapter

I have a 12x1.5 (I guess Nissan or toyota size) shift **** that is I guess 2 mm over the sixe of my Acura 10X1.5 thread pitch shifter shaft. Is there some sort of adapter I can use to get the larger diameter shift **** to fit on the shifter?

I guess I could saw it and get it remachined but I dont know anywhere to do that in NC...plus id have to uninstall and reinstall it...

Would it be possible to wrap the existing threads with elec tape and then just try to tighten on the new ****??

Thanks for any help.

That doesn't work. I have friends who have tried.

How about another approach...

Drill out the threaded part in the non-fitting shift ****. Find one of those long, hex nuts (1" long at least) that fits your shift ****. Good luck finding metric parts like that...

Then insert the new long hex nut into the drilled out shift ****. Epoxy it in and screw it on.

I have found a solution that seems permanent.

Went to lowes and found little rubber caps in the drawers with the metric hardware, etc...since there is no adapter that is made.

The caps were 3 for $.98 and I used the little bolt and nut tester to find the right size to go over the 10mm shifter shaft.

Bought those.

Then tried them on the shifter shaft as a sort of space filler, and they fit perfectly over the shaft.

So I pushed one over the threading of the shaft as far down as it would go, and then basically the new 12mm **** sat just on the rubber cap as the shaft + rubber cap &gt; 12mm, but it was the perfect size b/c the rubber is adaptable and allowed me to screw the **** on and hold it tight.

I tried to vertically pull it as hard as possible, and it wouldnt budge...Im sure if I had more leverage and wasnt hitting the roof with my head it wouldve come off after enough force, but it wont come off w/o a struggle and injury...

There is no play of the ****, vertically, or side to side pivot or anything.

The **** can turn a bit, like 10-15 degrees with not much force (and could turn infinitely b/c there is essentially no beg. or end to the makeshift rubber threads) but I wouldn't call it "play" in the **** b/c it isnt that loose.

I could Prob use a squirt of glue, but its not worth gettin it all messied up--Its a quality result, for a worthless problem in the first place.

Thanks for all the ideas that sparked this project!

I have a friend who had a similar problem. This is how he fixed it. First he found a nut that fit his shifter and ground all the edges down to made the outside of the nut round to fit snugly into the shift ****. Next he gently pounded the nut down into the shift ****. After it was securely in the **** he then carefully applied some JB Weld to the inside of the shift **** around the edges of the nut. Let everything dry and you can turn that **** on the shifter as hard as you want and it is still holding strong after over a year. Fits just like factory. I'm not a huge advocate of JB weld but in this situation it worked flawlessly. Just another idea I thought I'd add.
