You mention tranny fluid and filter elsewhere. Is the fluid level correct?

Not a mechanic so just reading and writing but a slipping torque converter doesn't seem to describe your earlier stottering.

I think we will stay at this thread.

I checked the fluid level this morning before I started the car.

The level is a little bit over the second hole on the dipstick, means a little bit over max.
