Installed Hurst short throw shifter..Question

I am new to the forum and to corvettes. I just bought a 2004 C5 with Cam and bolt-ons. I just installed the hurst shifter and have some questions. When driving it, it has a grinding sound that is noticably loud. It shifts fine and clean, but i am wondering about the wierd sounds i am hearing. Can any one give me any info on this. Thanks

Just so I understand your question...you're hearing grinding sounds when you're not shifting?

I'm assuming you didn't have any issues with the oem or previous shifter? Was this a new HURST or used HURST shifter? Did you receive instructions? You can contact or go to the HURST website and possibly find instructions and/or suggestions for installation/issues.

If I'm incorrect and you're hearing grinding sounds during shifting, it's probably nothing more than adjustment(s) of the internal rail shifter. On a HURST, there are two internal hex "stops" at the top of the tower body which can be adjusted for positive gear stops. Some people remove them for street use as they're not really necessary with the TREMEC.

Also, the four 1/4-20" mounting bolts allow for minor adjustments, although less so with the billet construction of the HURST compared to the stamped steel construction of an oem shifter.

Did you use the neutral alignment pin when you changed the shifter? You're supposed to insert the alignment pin (or suitable sized pin/nail) into the alignment slot to keep the transmission in neutral during R&R.

You can find hundreds of past discussions in C5 Tech, using search or search this forum (in the red banner). Use keywords "c5 shifter adjustment" or similar. Here's some...

Thanks for the information, I was not aware of the neutral alignment pin,so maybe i will have to look up how to do that and see if it works. But yes, there is a grinding noise when just cruising (not shifting) and the shifter is brand new.

You should have been able to install the shifter without affecting the neutral position since you do not remove the mounting base.
However, you may need to back the shift stops out on the front and rear of the shifter housing to make sure you are fully engaging each gear.
Technically, you do not need the stops since the stock shifter does not use stops but they can prevent forcing the shifter too far if you are rough on the car. I adjusted my stops by making sure the gear was fully engaged, then I adjusted the stops where I could still see light or slip a piece of paper between the stop and the shaft with some pressure on the shaft.

My Hurst shifter works fine but it rattles Like an SOB at certain rpm's. Can I adjust that out?

did you put teflon tape on the threads before putting the shift **** back in? if not, that may be the problem as the hurst rattles by design.

remove **** again and wrap lots of teflon tape on it. the **** will screw back on but real tight.

actually i didnt mean that the **** is rattling,my mistake on my wording. by putting tape on the threads absorbs the rattle noises from below. mine is silent now
