First off, the dealership should hook up the tech2 and record all the parameters while the vehicle is doing the downshifting event. It could be nothing more than a reprogramming need and that will tell them if a shift solenoid is marginal.
Second, when you bring your vehicle in with a complaint under warranty and it comes back as a NTF(No Trouble Found) or "Could not Duplicate", that is entered into the GM database and can be accessed by any servicing dealer and will be considered if you go out of your warranty period if/when it fails.
Just keep your documents in the vehicle.

I dont really agree with the statement made by Dave in regards to the Could not Duplicate issue. Yes it does "usually" get put into your claim history database under GMVIS however it means exactly that. Could not duplicate. Such a entry does not make it clear cut as to a issue under warrenty. Granted Its usually up to the dealer however cost assistance or coverage is not guranteed unless its been diag. Also if you ever have another dealer do work on the transmission getting them to cover it under the issues you had with it under warrenty will be a even greater stretch Please trust me its best to either have them check it out again or go to another dealer for a diag. I mean those issues could be any number of things. And to be honest its unlikly they will cover ALL the items that it could be under the liklyhood that it could of been causing issues under the NCW.

You could always make a case for Cost assistance down the road But the fact that it was not DIAG as a problem under the NCW it still makes building a bussiness case that much harder


So my advise would to keep on it have it diag and repaired while its still under warrenty. That way if it does happen to fail again outside of warrenty You can still get help

Thats just my two cents
