Just to be Safe

So I'm a fairly new Chrysler 300c driver as I just bought mine around 3 weeks ago. The other night I was driving home and my car seemed to stick in the high RPMS around 5-600 and would not downshift for a little while. Is this a transmission issue that I should look into further or just a one time kink? Thanks for your feedback

"seemed to stick in the high RPMS around 5-600": when?

What year, how many miles, and what is its service history?

Well I hit around 70MPH then when I began to brake it would not drop in RPMS. So I braked again and eventually it dropped. Car is 2006 300c with 115000 miles. Perfect history with 0 issues just regular maintenance

Did it seem like when you were braking that they were fighting against the engine, like a stuck throttle?

Yes it did sort of, it was odd I kept speeding up then braking but it just stayed where it was around 5-6rpms

First: If you were at 70 mph ("5-600 RPMS" ????) and going down a grade the tranny itself was probably in a reduced gear to hold the car back until some throttle was applied or the speed substantially reduced.

Second: Was the transmission fluid and filter changed as part of the "regular maintenance"? At 115K miles it is on the cusp of its second change.

Typo meant 6000 lol, and I'm not sure if the dealer changed the Transmission fluid and filter so I'll look into that thanks

If it went to 6,000 RPM the tranny probably went into "limp mode" to save the engine from grenading!

Pedal stuck on the floormat? The throttle is fly by wire and if the Pedal position sensor fails it usually intermittently jumps around and then stops registering (ie no go)...

I'm still not 100% sure what the symptoms are here as it's not too clear.

So you floored it and let off and the car stayed at 6k and would not upshift or decelerate?

Going down a grade? Didn't see where that was the case, however correct if that's the case, it makes sense but hopefully someone with a DL would tell if a car was engine braking from a down shift.

Silvertongue06devil () brings a great point regarding something many of us forget about the throttle.
