2004 Cummins 48re. Drove it in the morning, no problems. Got in to leave for work that night and it wouldn't move. For some research I found that it was probably the governor pressure solenoid or transducer. So I replaced both of them. It still will not move

Sadly I'm not sure. I would say its time to pull the entire transmission out and check the clutches and bands.

How many miles on the transmission?

Any error codes or check engine light?

When was the last time it was serviced (fluid change and filter)?

With the 46RE, 47RE and 48RE are basically the A727 transmission with an upgrade of 4th gear. Now that being said, 1st, 2nd, and 3rd gears are all hydrualic shifts. THe 4th gear is "E"lectric shift. If there is no movement, I would start with pressure testing to see if the pump is producing enough pressure. You might want to stop by the DDownload section grab a service manual.

46RE, 47RE and 48RE

4 gears forward

6,7, or 8 the amount of torque on a scale of 0 to 9

Rear wheel drive

Electric 4th gear shift.

Here is my transmission book for the 48RE.

But..., before you replace any parts - make sure the transfer case shifter is NOT in neutral. Just sayin'...
