ECM Rollback

Looking for some ideas about shifting. My truck has had a 3-5 flair and something that resembles a flair in the 2-3 shift. My truck does it tuned or stock, doesnt matter. Now here is the big kicker, I have a new transmission with a modified direct drive and it still does it. It has done the same thing new or old trans, and tuned or not tuned. Newest strategies are VXBC9E2/TQBF0H4 my last ones were VXBC9N8/TQBD1N6. My big question is if i rollback will it help my shifting problems(im on the verge of getting rid of the truck because of it). Thanks

Have your tune writer write you a tune based on one of the earlier strategies. When you load the tune you also load that strategy. No need for an ECM rollback.

Exactly what match said. I had Eric do this for mine. He did a roll back through the tune. I did it for using the ebp sensor. The new strategies don't use it.

Question is it possible to still run a newer strategy , once a rollback has been done? I understand the older strats use the ex sensor and the newer strat does not.The reason I ask is because Bill did rollback on my truck , one of the tuners adjusted my tunes for the older strat , but the other said after looking at the differences no adjustment was needed , this was for a tow tune,not sure if that matters.

yes, you just need a tune written off the newer base strategy, it doesnt matter what is flashed into the pcm because it can be over written with any other strategy.
