We tried changing the speedo gear with a different tooth count from the vendors (9-34 housing) also based on non stock tranny issues and it didn't work and mesh properly. Went back to the stock gear and a Speedo Gear Adapter based on ratio, or % high or low with some math calcs.. Not cheap, but can be found on ebay and can be provided with varying cable end adapters. Checked with cell phone app. and speed is accurate.
