Attached is a recording of a strange whistling sound my 2017 Access Cab 4 cyl auto trans makes when accelerating as it shifts into 3d or 4th (30-40 mph), only when the A/C is on.
The recording is a bunch of different occurances clipped together - it doesn't happen continuously, usually just once per acceleration. Seems to come from the under dash or floor area in front of the passenger seat.
Has happened since it was new, and a number of dealership "solutions" have not worked. Dealerships have done two fixes to the A/C (one was a recall), then most recently some holes that were missing plugs were replaced. Still making this annoying sound. Really sounds like something straining as the truck shifts.
Main concern however it that it signals something that might go really wrong (like, with the transmission) after the warranty runs out.
Does it sound familiar to anyone? Any ideas?

Trying to get a lot more people to listen in case someone else has had the same problem.
