Bought used. 5.7 Hemi RWD. 247000 miles
When first starting up, sounds like the engine is roaring. Quietens down after a few minutes. Thought it was just warming up. BUT, when I accelerate, engine roar is back as if in 4WD super low (not a 4WD truck). It is slow to change gears and roar gets louder. Roar then goes away as I pickup speed. I stop at light or stop sign, same thing happens. I hope my trans isn't going bad. I never had a Mopar sound this way. Wanted to put a glasspack on to hear that Hemi, like in my Charger, but I won't be able to with that roar! (Yes I am Mopar nuts till I die, Ha Ha) Any help would be highly appreciated.

 

its likely from the fan clutch on the engine they can be loud moving alot of air.

 

Clutch fan. Mine does it

 

I am working on converting my 08 engine cooling radiator over to electric fan, because I too, do not like the stock fan noise. As soon as I get it installed and tested, I will post a writeup on how to do it.

 

Mwillia, did you get the electric fan in?

 

Not yet. I am dealing with a fuel pump problem now. I won't be able to start on the fan until spring, as I can't get the Aspen in the garage.
