Hi all! My 2010 Camaro SS A6 is making a buzzing noise as it upshifts. More noticeable when cold especially from 1st thru 4th gears. Shifts normal otherwise; no grinding, no slipping. Fluid was normal. 6L80 with a 36-3800 stall (added 17k miles ago during cam upgrade). Anyone experience this? TIA!

Usually there are 2 things to go back and check with a converter swap.
1. The fluid level needs to be checked when warm because no matter how hard a person tries to fill the converter before installing it, the process can still lose some and the converter is just not ever really full after install. The prefill just prevents dry startups from trashing the new internal parts. The A6 trans has a plug where the dip stick would NORMALLY be There is no dip stick on the Camaro from the factory like the old days.
2. The other thing is it probably needs to have a Trans tune to get the line pressures back up to allow the solenoids to build up pressure. A GOOD tuner would know this. Too low and the transmission act it is low on fluid. Too high and the seals will blow=trashing the transmission.
