well mine wont shift right if either sensor is unplugged so id imagine so
So the minimum list will be :
1. all 47RE internal sensors and solenoids
2. battery voltage
3. TPS
4. engine rpm
oke:
Well it might need the Tcase output speed sensor, I forget if I pulled that.
.. but up to 98 transfercase output speed sensor is vechicle speed sensor
From 98 no transfercase output speed sensor , speed is calculated from rear diff ABS sensor (tone ring)
WOT and Normal - can identify by TPS signal
COLD- from transmission temp sensor
4WD low is still mystery
But in 2wd application VSS is not needed?
