Loud noise and resistance when shifting from Park to Drive or Reverse.

I engage the park brake and the regular brakes before shifting the gear to Park & do the same before shifting from park to drive. Since my driveway has a slope I have to do this on a daily basis. I face the same problem with my 2001 Honda Odyssey. I would like to know how parking on an incline affects the transmission as my transmission has failed thrice since November 2000, I know this model had a problem with transmissions.
