dodge 2003 hemi 3500 came with a 4-45rfe transmission this transmission is in aspens mini vans 1500 and other cars and does not hold together in a 1ton truck.At 51 thou miles the 1st transmission failed the 2nd failed at 115 thou miles both with no more than heavy half ton loads only.The hemi motor has been very good so far great power smoth I can not say one bad thing about my 5.7 motor hemi I had some brake issues but nothing over the top they stop very well. the ride for a 1ton truck is good.The rear end of this truck has 373 or 410 gears but on mine has not been tested with heavy loads.the inside on slt is basic but good.dodge stopped this combo after 2003 in the 3500 hd I cant recommend
motor and air and heat
transmission and again put a truck transmission worthy of a 1ton truck this combo the 2003 3500hd with the 5.7 with an atuo transmission is like having a big big farm work horse with legs of a goat the horse (truck) wants to go to work but its legs (transmission) cant support near the loads it should.
