Our 2015 Impala drives great, has occasional light flare when cold in the 2-3 and a less occasional 3-4 flare. These flares are brief..almost seems like the trans is "confused" for lack of better terms.
I did read there was a refresh for some of these 6T70's that addressed pressure issues, not sure if it was for the Impala.
With HPT, could I find out if there has been a reflash and/or are there any recommendations for dealing with this trans in regards to a tune? I understand the latter is at my own risk.
The car shifts great most of the time, fluid looks good, been changed every 50K, has 154K on it. The 2-3 light flare when cold has been doing this since about 90K miles...but only very occasional.
