Ok, serviced the tranny and still shifting hard. Put stock setting back on and not shifting hard but still shifting a lot. I found a way to watch MDS Mode going down the road on the edge and thats the problem. Every time it shifts hard its coming out of V-4 to V-8. Doesn't look like anyway to turn it off with the edge. Anybody know of another way to disable MDS on a 07?????????????????

 

Short of getting a Superchips or Diablo tuner or custom tuned SCT - nope...

 

Which superchip tuner do you think works the best...
