2000 Dodge 1500 conversion van with 5.2L 46RE 3.55 and 96k miles
Typical 46RE shifting symptoms..
jumps between 1-2 when shifting from 1 to 2
holds the 1-2 shift and 2-3 shift (will hold the 2-3 shift very long,
I usually let off the gas until it shifts)
engine will sometimes 'flare' during shift, will rev up until shift is
shifts feel 'soft'
using a Snap-On Modis scanner, looking at
desired gov pressure
actual gov pressure
governor duty cycle
pressure sensor voltage
pressure sensor voltage stays around 0.45v - doesn't change (this
might be a failure of the scan tool to read)
desired & actual gov pressure stay pretty equal through 1st and 2nd
gear, governor duty cycle is around 25-30
When it shifts into 3rd gear, the desired gov pressure reads 127psi,
the actual runs from 40-70psi depending on road speed (goes up as road
speed increases) and duty cycle goes to 1. To me, it sounds like the
PCM is asking for more pressure, the governor solenoid goes to full
open, but can't attain desired pressure. Desired pressure also seems
high.. over 100psi?
My plans are to measure some pressures, check for good power and
grounds, drop the pan, change the filter, pull the governor solenoid
and look at the screens for trash. Adjust the bands and see what
Anyone have any thoughts?
