P500 Transmission clatter

[SLR]

Hello, I have a 18 p5 and have noticed that when at 30+ mph if I go to stop fast “applying the brakes”the transmission feels like it it trying to downshift and makes s hell of a clatter until stopped . I noticed yesterday on a heavy decline in 1st applied the brakes and same chatter. I got about 400 miles on her. Anyone else noticed this? Sure would like to know if it’s just my girl or others have the same issue? Thank in advance

They all do that, nothing to worry about. If you just don't want to hear it, get a Shield.

Summer is coming, best time now to get that Trigger Shield installed, no sweat then and dampen the noise All seasons.

Mine does that when it's low on oil. Top the oil up and it doesn't do that rough downshifting...
When checking the oil level, make sure you DON"T screw in the dip stick. Just dip in in and out to read level properly. And a little more is better than a little less.

My 17 did it too.It was the auto downshift feature causing it.I say "did" it because I changed my electronics to 2015 stuff and rid myself of that awful chattering.My 17 model acts the same as a non-auto machine now.Much better in my opinion.That chattering from the gear searching when coming to a quick stop from higher speeds can not be good for the drive train.
