I realize that the 3.7L, 4.7L, and 5.7L engines and 45-RFE and 545-RFE transmissions were recently introduced over the past couple of years, but I am curious to hear if anyone has heard of one of these engines or transmissions being overhauled yet? I did a search just to see, and nobody I found appears to be up to speed on these yet.

And just to be clear, I'm just asking for the sake of curiosity... my 5.7L Hemi Quad Cab is doing just dandy with 17k on the odometer.

 

No I haven't heard of it yet, and hope I don't for a long...... time.
The only reason I could see for doing a overhaul at this point is because of some serious mods like stroking the engine and adding heavy turbocharger boost along with some high precision balancing and blueprinting. I think I'd go with a completely different engine and drivetrain setup aside from starting with a stock engine/ trans combination.

 

im with gone fishing i hope i dont hear about that for a long time. but if their is i would have to agree with him about boost or just plain beating the Cr@p out of it and not doing the recommended maintance like changing oil and stuff
