If you want to upgrade your transmission to a 4l80e, we can help you with the tuning process. We can either reprogram your existing transmission control module (TCM) or provide you with a new one that is already tuned for a 4l80e. We will also adjust the settings according to your specific tire size and gear ratio, so that your vehicle performs optimally. Contact us today to get started.
