I have always popped my car in neutral while at a stop for very long, and then dropped it back in drive when taking off. I don't put it all the way up in park, just put in neutral and keep you foot on the brake. When stopped while in gear the trans slips. Putting in neutral has always worked for me, I change my fluid every 35k, always use the parking brake while parking the car, and have never had a failed transmission in any car I have ever owned. My 280C had 465k on it and the trans shifted really well. Good luck!
