It's got a noticeable hesitation. Do you think it's time for a total rebuild or are there localized problems that can cause what I'm experiencing? Thanks, this is my work vehicle that runs the interstate all year, I don't want a break down while traveling.
4.7 = 45RFE. Fully electronic, no cables, kickdown levers, bands, etc. It could be a speed sensor, could be a solenoid... but whatever it is it will likely be electronic in nature. Changing the fluid/filter(s) (the 545RFE has two, I imagine the 45RFE does as well) and checking the codes are your best options.
440 Magnum nailed it on the head . The 545rfe trans is fully electronic so there are no manual adjustments. I second changing the filters/fluid , use a high quality filter in this application such as Mopar or Wix. ATF+4 only , nothing else. If a trans fluid change does not remedy the symptoms most likely culprit is either the shift solenoid pack or the speed sensors.
