A lil update had an issue with code P1239 from time to time. This code would of course put the Z into limp mode. Turn off back on and all good for a Day or Three. Code then started to show itself more frequent so after some research narrowed it to the jumper cable for the T/B. Mark from Stillen got me a new one shipped over. Changed out and now code free once again. Z now has 80K miles running and shifting just fine. Below is a lil fun from TX2K15 weekend!
