The TW-GSC (gear shift controller) is required for TW Gear Ratios: 70/30/15, 45/15 and 45/15/1 in the SS Model YXZ. Our GSC utilizes advanced real time processing technology to allow for our Tubeworks aftermarket transmission ratios to function seamlessly, without modifying the stock Yamaha ECU and sensors. Our GSC also allows the speedometer to read correctly based on tire size and gear selection. *Our Engineers will write a custom program for any other ratios desired for an added programming fee of $135.00
- All data is proprietary to Tubeworks Inc. and programmed to work with your vehicle and its specific gear selection and tire size before being shipped.
- If and when you change your tire size you may send your GSC back and we will re-program at no additional charge. *Shipping charges apply.
- Installs with ease and very little effort.
