I purchased a 2003 Z06 with around 75,000 miles on it. During the PPI the mechanic made note the shifter was terrible and might need a rebuild. I purchased a low mileage 2013 ZR1 shifter assembly. That shifter assembly only had 13,000 miles. I installed this setup and still had some issues. I even went as far as changing the ATF in the transmission and doing the antivenom mod. Shifting action was still not great.
I finally sent off my stock Z06 shifter box and had it rebuilt by TMODCustomz. I installed this yesterday and went on a long test drive today. The car after it was warmed up did great. I can easily get into reverse and shifting action is much improved. It feels like the modified rebuilt box has a slight spring action in it. That really helps with the shifting motion.
TL;DR=Box makes a difference and fixed my shifting problems.
As soon as it uploads I'll shre a video of a low mileage/ great condition lower box and the feedback from the customer who changed it out for our lower box.
No more extra waiting for Z06 boxes! Solid bushings are available now, no matter what box you have. If you have a non-Z06 box and want to upgrade to a solid bushings it's ten bucks. If you want to buy just the bushings it's twenty bucks shipped.
I'm still torn on which bushings to use! These Delrin ones (pictured) fit perfectly and basically snap snug into place. We'll see...
I got some nice Mobil 1 grease for the shifter cup and 4 new bolts to connect the 2 shifter halves (broke 1 of 4 originals installing my current ZIP Corvette polyurethane shifter bushings back whenever that was). Install thread incoming; I'll link to it from here once posted.
Chalk me up as another satisfied, although incredibly particular, customer! Thanks again Tom, your customer service is 2nd to none. My core is already in the mail and you should have it Tuesday.
Now I'm even more excited for my ~350 miles of aggressive twisties next weekend on the annual group car cruise from Dallas, TX to Shreveport, LA I'm putting on!
