Hey gang. I'm running a FiTech Ultimate LS swap with transmission control on my LSx and 4L60e. Has anyone out here dealt with the issue of the transmission not shifting out of first gear. Also the handheld controller is showing a speed of 0 mph. I' have read a few things on the internet and tried them out, but still no change. I've heard FiTech support is pretty slow, so I've come here first.
Thanks
Thanks
