I have a tC with manual trans, i bought a new shift **** for it on ebay and it doesnt fit right. It doesnt have threads to just screw on like ud think it would, instead it has those 3 little hex screws that u screw down to tighten it on. Ive tried it with every little insert that came with it and no matter how hard i tighten down the screws the **** will just spin and if i were to drive it for even a little while im sure would just come off. There was also a different shift **** in the console when i bought it that fits the same way. Is there any kind of adapter or something i can buy? Or some way i can make one of theese shifters thread onto the shaft? Or at least a way to tighten em down so theyre secure?

 

You can grind flat the threads where the set screws meet the shifter and this will give them much better purchase. In general though you want to get shift ***** that are threaded so that they mount more securely.

 

Buy a screw on one.
those dont hold.
