2001 Honda Accord Transmission or Electical issue

When I start the car and put the transmission in D I get a jerk, when I start driving the others shifts are pretty good unless I have to stop quickly,
then a get a jerk again, the problem appears to be worse if I have a hi electrical demand (lights, A/C, etc.) Then the problem disappears after 15 or 20 mins of driving, and everything works perfectly until the next cold start. Also my dashboard lights always are flashing and if I put the turn lights my instrumen cluster go crazy the same is if I move the shift gear fron D to N or P.

I don't know what to think.
