On occasions, while driving around 45mph or faster, and coming to a complete stop my car will feel like it's surging very slightly while my foot is on the brake. I've asked the dealer about this and they were puzzled. Whether cold or up to operating temperature it does this. Even have had the trans. fluid exchanged just to be safe.

If anyone may know of the cause, or correction please let me know.

Not normal, it sounds like your torque converter is sticking on. That is out of the ordinary because 99% of the time the problem is that it doesn't hold.

No Torque Converter Clutch Release
No TCC Release Checks
Causes

TCC Solenoid (335)
• Internal failure

• A plugged fluid exhaust

• An external ground

Torque Converter (55)
Internal failure

TCC Regulated Apply Valve (339) and TCC Control Valve (344)
Stuck in the TCC apply position

Thanks for the insight, how should I go about asking the dealer to look further into this? Is there anything I can print out, that can show them that this is not normal and there is a problem which you have done.

Thank you for the help Chevycustsvc, I dropped my car off at the dealer last night so they can look at today. So far, no news as of yet.....which means hopefully it acted up for the technician. May I keep you in mind should the dealer need a helping hand to find the exact cause of this issue I'm experiencing? Thank you again for helping me in my time of need.

Update!!!! I was able to take a test drive with the technician, and at first it wasn't doing the concern. Well, when we got back to the dealership and I parked by his bay is when it did it. He kept the car throughout the day to make sure, in the end it turns out to be a misfire in one of the cylinders. The most he read on the scan tool was 10 at most. So being as random as it is, until the "check engine" comes on or a message on the DIC appears or it just gets worse and more frequent then they'll surely know which cylinder(s) is/are acting up. He wrote on the RO and I saw on my repair receipt was it can either be a possible coil pack, or what's called a DIS module.
