There is already a post in the TCM section but no replies. This issue is driving me crazy and costing me money. I went through every setting in the DVT to get the trans to hold 3rd gear or lock the converter with no luck. It feels like it is right just rolling on the dyno but when I hit the gas and it shifts from 4th to 2nd or 3rd to 2nd without fail. Even rolling into it didn't always work. I finally just wrote a tune that doesn't allow it to shift into 4th and won't allow it to down shift into 2nd. I was out of time on the dyno so I will have to see if it works later. What is the deal?
