45RFE / 545RFE

Looks like a 45RFE or a variant thereof

Yup, I was thinking NAG1 but 545RFE is the correct answer..

What is it, a 4 speed & what would it have come in?

 

[1 Wild R/T]

Five speed with two overdrive gears... And a pretty deep first gear...

I almost signed up for anger management therapy over my 545 in the 4x4 Dakota. Had a harsh 2-3 shift once warmed up and inevitably going into limp mode. Tried everything possible externally and finally bought a remanned unit and swapped it out myself. Never did find out what caused the problem. Most of the time when it threw a CE code it was insufficient gov pressure. Luckily no problems with the new unit.
