PlayStation Class 45 Engine Jam/stall

Hi guys! Sometimes when I use the class 45 spefically on grades I notice that I get this jagged red indicator on the speed HUD and I hear the engine gargle and rpms revving up really high. Anyone the cause of this and how it can be prevented?

 

That’s the wheels slipping. You need to ease off the throttle when it happens.

 

Thanks mate!
