Auto Went Past Redline

[BMW-ATI]

today i was kinda just testing my car, and I floored it from a standstop(dont worry i oly do this like once a month)
and like it went past redline and like did that idle thingy when it redlines, for like a sec
is this normal
and i think I may have figured out something, my laggyness only happens on hot days, the thermometer goes past halfway a lil bit
maybe i need to bleed my radiotor and put new coolant in it?
or is it maybe my water pump?

It's normal....It's the engine cutting fuel flow in order to save itself from any damage....

but why did it redline in the first place

good question, it really shouldn't be doing this in the first place with an automatic. how is it programmed? the programming may be off some and need to be restored to default or somehting.
