Brought my 2016 hyundai genesis rwd 3.8 8 speed automatic, 46000k on odo, to dealer to have trans fluid changed. Here's what happened. I told them specifically to use fluid exchange machine ( not drain and fill) no chemicals. Change filter and use the proper required ATF-SP-IV-RR trans fluid. After service performed 2 hours later. They come out and say there is no trans filter which is wrong, we did drain and fill, not an exchange and on the service order it says they used ATF-SP-IV-M trans fluid.This is the wrong trans fluid. They do not have a service manager and this guy didn't know what he was doing. He also said you can't use trans fluid exchange machine on a sealed transmission. Question #1 can you use a trans fluid exchange machine on this type of tranny or is that B.S. and will this incorrect trans fluid damage the trannsmision. There is also a powerful odor of used trans fluid in the cabin even after its been sitting overnight off. There is no visable fluid in the car. He also said he broke a wrench trying to remove drain bolt or something like that. I'm very angry and worried about this. I'm going back there this morning and expecting the everything fine tell you want you want to hear bologna. So fact based assistance would help. I'm also the 2nd owner and powertrain warranty is almost over . Also trans fluid was brownish dark red proving that you should never believe owners manual recommendation of 60k mile trans fluid change. Thanks
