2016 Tahoe LTZ Transmission issue (P0741 Code)

No thoughts beyond taking it back to the shop to have them fix it, if they caused the problem. If they didn't (or if them simply disabling the AFM resulted in lifter failure), it will need to be fixed one way or another (if it's your lifter and not an injector). I think some scan tools can perform injector balance tests, not sure which one but if you have a bidirectional scan tool, check it to see if you can do that with yours. I'd rather diagnose it myself than take it anywhere. At least you know for sure (assuming you do it correctly) what the problem is vs relying on someone else who may or may not be honest w/you.

thanks @NickTransmissions or the reply. I just dropped it off at a local shop. At this point I am guessing it's the lifter and so will be looking at possibly cam and lifter replacement. Hoping it's not more significant than that. I'll let you know what I hear back. Thanks.

You're welcome. Id def do a full DOD/AFM delete with a non AFM cam, etc. that DOD crap is responsible for an awful lot of engine failures...

Sounds like that's what I'll end up doing. Just hope nothing damaged in the engine requiring more repair dollars. Cam and lifters alone will be a couple thousand.....
