I'm trying to get my trans to shift automatically before it hits the rev limiter when in manual mode. Too many times I've bounced it forgetting to shift using the paddles. I've heard several tuners are able to do this.
Looking at the trans tune it appears that ECM 6509 should make it shift at a Mph I set. It does not work on my trans.
What am I missing, Thanks
[ECM] 6509 - Trans WOT Vehicle Speed in Select Shift: When select shift is active, the vehicle will shift at these vehicle speeds.
