98 prelude , clutch problem or transmission?

Hi I have a 98 semi automatic prelude but I drive it mostly in auto. When I reach the gears for 1st and 2nd gear the car jerks back. As soon as I stop, it starts all over again. I replaced the transmission fluid with Lucas no slip and more trans fluid. Do you think it’s the 1st and 2nd gear clutch that’s broken or needa to be fixed? Or is it the transmission starting to slip?
