6R80 Upshifting Issue

[ELDiablo]

Just got my new combo together and took the car out a few times breaking in the new motor. I’ve come to notice my transmission seems to have an issue both in Drive and Sport modes where it will upshift so quickly that by the time you’re going 45 mph the car is already in 6th gear. Has anyone else had this issue? With my old tune (different tuner) id have this issue sometimes but only in drive never in sport. I asked my current tuner they keep saying everything is fine on their end but obviously something is wrong. Thanks

Sounds like the stock shift schedule. It is easily changed by any tuner.
