1994 Acura Integra 1994 Acura Integra automatic transmissio

When my engine downshifts as I'm coming to a stop, should I not stop entirely and my trans downshift is in 2nd and just about to shift down to 1st, then I accelerate (ex: if a traffic light turns from red to green) it slips until I let off the gas peddle. When I feel it grab then it is OK to accelerate again. It's been doing this since about 3 months after I bought it used in 2004.

My trans fluid is red and the level is at the top of the knurled section of the dip stick. When I check the fluid level I run the car until it is fully warm, then shut it off, put it in park, open the hood, check the level, wipe off the stick and check it again.
