I just got my 3500 4x4 SRW 48RE CTD HO last week and I really like it. GOBS of power. VEEEEERY quiet, until you floor it. This truck is vastly different from my '01 2500 CTD LB 4x4. Almost like a car, or nice SUV, but lost a lot of it's big truck feeling. Drag raced a co-worker last night who has a lead foot and chevy with a 350. I kept right up with him, and my turck only has 300 miles on it. With a heavy throttle and when the overdrive shifts in, it seems to have a surge of power at 1400 rpm. Everyone who complains about the past trannys seem to bomb their units. I don't plan to do that, I save it for the other toys! A good friend of mine is the transmission tech at the local Dodge dealer and he said it's not unusual to see people drive in to have their automatics serviced with over 200k on them and they have never been rebuilt. The trucks are stock CTD and V-10s.
My goal is dependablity and reasonable economy. Only time and miles will tell.
