I made this model to fix a broken transmission cable bushing on my 2012 GMC Sierra 2500 so that is the only vehicle I can confirm that it works on. 

I printed mine in PLA with 100% infill and it is working so far, not sure how long it will last though so I would print a couple extra to keep in the glove box just in case! Would recommend printing in something a little stronger. 

simple install, just press into the shift cable then press on to the shift lever shaft (If thats what its called). I had to use pliers for that part.

DISCLAIMER: I am not guaranteeing this as a permanent fix. Use at your own risk.
