Upgrading to 3.91 gears - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Looking for a good shop that can upgrade my 2011 to the 3.91 gears and then update my speedo to match the new gearing. I checked with my dealer and they cannot do the software update. I'm in north jersey and looking for the closet shop.

Your dealer may be aware of the GM re-flash for the gear change.

If you're concerned about keeping your powertrain warranty and you have another dealer nearby, check with them.

If you go the dealer route, I'm curious to what they quote you.

The dealer can't do it because they don't have access to the software upgrade for the speedometer.

+1 I drove up to his shop from VA to get it done... plus other items in sig. Got the full kit with Eaton and his billet end caps. No problems.

If you're that close to Jannetty it's a no brainer! He's the one who came up with the posi fix and he's done tons of gear jobs! Just ask around!
