I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

3-4 shift flaring when cold & in "D" only

Newbee here & to 6L90 tuning. Be gentle :)

Thank to Evil for turning me on to the site. I remember a post on CTSVowners from RB a while back, but just didn't make the jump. Anyways, I'm here now & hope to learn...

As the title says, mine flares about 400 RPMs (on lite throttle) in the 3-4 shift in "D" when cold. I have not & will not do a WOT 3-4 shift while cold. If I switch to sport mode, no slippy & it shifts firm as it was tuned to do so. The "D" tune unlocked the TCC in 1-4. Also, after she warms up, the 3-4 shift in "D" is fine.

Your input is appreciated.
