2016 Tahoe 6spd not shifting

[Tiredmechanic23]

2016 LS 6 Spd. Started to stutter like a torque converter issue at light throttle but that was it. Today I left the house and got about 10 miles and it hits neutral when shifting to 3rd. 1st and 2nd and reverse are fine.

No codes as checked with my Modis Ultra. Solenoids check out according to functional test. Its just due for the trans service by the manual service schedule.

Any common issues for this or am I out a trans lmao. 3 years old had it since new.
