Default Transmission problems

Recently upgraded my automatic transmission in my C7. Mechanic changed the “transmission computer”. Transmission worked great for the first week, but now having issues. Extremely hard to explain, but when coming to a stop, once transmission shifts down to second or third gear, the car will stop itself almost immediately. I then have to put it in park and then back to drive. Obviously this is an issue, but an extreme issue when there is a car behind me.

Update.... the car will no longer drive forward. Once shifted into drive, the car acts like it is stalling out and will not go forward. Luckily this started while I was just down the street from my home and was able to reverse back home. Thoughts?

Sounds like dealership time.

Obviously you have some real problems. A torque converter that is not unlocking is one of them. Is your mechanic a gm dealer guy or independent?

That seems like a mechanical issue inside the transmission. I had a pump go bad inside one of my transmission once and I had those exact issues.

Thanks for the responses. My guy is an independent guy. The pump had to be replaced and has a new one in now. Maybe a bad pump?
The car is now back in the shop and he will attempt to figure it out. May end up having to take it to a dealership, but the issue with that is the car has been upgraded in so many ways, to include the transmission.
