1998 Mitsubishi Eclipse Vibrations at the end of my stop.

1998 Mitsubishi Eclipse 4 cyl Automatic 137000 miles

I can be driving at any speed, when I reach a stop sign or red light and reach the end of my stop, I will get some vibrations and it acts like my transmission gets stuck. The vibration usually last about a second; what I usually do is release the break until you can tell the gear picks up again and I can drive again. My car is also making a weird noise every time I put it in drive or reverse, does all this add up to a transmission problem? It gives me no problems while driving.
