rougher downshifts after tune

[Big Mike 74]

I have a 2011 pp just did the 3 bar map and thermostat has about 200 miles on the new 4xtune from LMS car seems to downshift harsher and when I let off the throttle hold itself back a bit. Should I re load the tune and see if that helps? Any thoughts would be greatly appreciated

Any particular gear combo, or any gear combo? You can request shift pressure be reduced in the tune and see if that resolves anything. The PCM should have recalibrated to the tune in the 200 miles. Can always return to stock and see if the issue manifests there too. If it does, time to look more closely at engine/trans maintenance.

Also worth looking through the TSBs for 2010-12 to see if anything strikes a chord.

Its like anything under 40 mph when I let off the gas the car holds it self back for a second then shifts and glides normally

Does this only happen when the powertrain is cold? or not fully warmed up?
