Hello to all Dodge fans!!!

New thread, new to forum. I am from Europe, Poland. Our highway speed limits are 80Mph. I am driving very often to Germany-there is no speed limit (only recommended speed 80Mph). My question is if this speed will kill A/T? This car is my first with A/T, I have no experience that is why I ask for advice. Thank you for any reply.

If you're just sustained cruising, than it won't do much more damage to the transmission than say, 65mph... However the higher speed means the car has to work much harder, over come more wind resistance, etc. That can be a little rougher on the engine. City driving is what will wear down a transmission quicker, with the constant switching of gears.

 

It shouldn't hurt anything other than gas mileage lol.

 

i am almost positive that the manual 111mph(2.4 liter) and 117(3.0 liter) are the driving ranges that may be driven without causing engine to operate in excessive engine speeds.(That is straight from the manual page 159)

 

I think what you are talking about is in the tallest gear (5th for the manual and 4th for the Auto) at those speeds going faster could cause a mechanical over rev situation.

Sustained high speed will create a large drop in fuel economy, faster tire wear, the sustained higher engine loads will cause crank bearing, piston ring seals ETC to wear faster of course this is over the course of 50K + miles. Still severe stop and go driving is worse on the vehicle then sustained high speeds (80-90MPH)
