I have a 2010 Dodge Challenger RT Classic with a 5.7L HEMI 5 speed Automatic Transmission that "Clunks" when shifting from PARK to REVERSE when parked on an Incline, but dose NOT do this on level surface. I have a little over 15,000 mile on the car. I took the car to a mechanic to have it looked at and they said the Automatic Transmission needed some Software Updates. I do not know why the manufacture dose not inform owners of this. I got the car back and parked my driveway with a slight incline. Next morning it STILL CLUNKS. The car has NO ISSUES when shifting on level surfaces from PARK to REVERSE. Do you have any suggestions on what may be causing the Clunking noise. Should I take it back to the mechanic. If I do that its possible they sell me on more expensive repairs.
Next morning it STILL CLUNKS.
Pull the parking brake up, then put it in Park. You're stressing the heck out of your parking pawl when you just put the transmission in Park and you leave it sitting on an incline. Always pull the parking brake before setting the transmission into Park when you intend to Park on inclines. The owner's manual says this.
The car has NO ISSUES when shifting on level surfaces from PARK to REVERSE.
That's because you're not putting pressure on the parking pawl.

I do not know why the manufacture dose not inform owners of this.
Maybe because the car is 15 years old and not the subject of a federally-ordered recall?
