Cab Reinstallation - P1876 P1816 Won't move

I'm reinstalling the cab on my '02 F250 and have gotten everything (almost - more later) hooked up. Went to put the truck in gear and it doesn't move. Tried both 2 hi and 4 hi with no luck, the 4x4 light on the dash comes on when put in 4hi.

Everything in the transfer case/tranny were working fine before I pulled the cab to swap engines.

Here are the codes:
P1876 - Transfer case 2-wheel drive circuit fail
P1812 - 4wd mode select circuit fail
C1230 - Speed Wheel Sensor Rear Center Input Circuit Failure

When I had the cab/bed off I replaced the broken plug on the transfer case. I was sure to reconnect all the wires to the correct ones on the new plug and soldered/heat shrunk everything.

Below here has been solved, thanks!

Finally, I've reconnected everything in the engine bay but I'm not sure what these two connectors go to? They both come out of the same harness, hopefully the pictures show it better. Do these have anything to do with the lack of movement when in gear/codes?

One is the idle air sensor that goes on the air intake tube and the other is for the master cylinder reservoir i believe. I'll have to look later on . . .

So it won't go into drive, reverse, etc . . . or it won't go into 4 wheel drive?? Check the shift cable that goes from the column down to the trans . . . it has an multi tooth black plastic adjuster on the trans. Sounds like you either broke the cable or didn't hook it back up.

Good call on the intake sensor. I think I got all the MC stuff hooked up, but I'll double check that. The shift line is hooked up and works fine - plus that wouldn't throw the codes that I have.

Check your line pressure . . . sounds to me like that torque converter is not working correctly . .. i'll check those codes out later on my scanner and see what i come up with.

I cleared the codes and have cycled the ignition a couple times, switching it in and out of 4x4 and have't seen the 1812 code come back. I can also hear the 4x4 motor engaging and disengaging on the tcase.

I had put 9.5 qts of trans fluid in, but called the shop that replaced the front seal and tc bushing on the transmission while it was out. He said the transmission would be nearly empty and to add more fluid to it. I'm at 16.5 qts now and its dumping it out at this point and I still have no movement from any gears forward or reverse.

It does appear to be holding in park fwiw.

Thoughts now?

Is the tranny shifting itno D or R in the first place?? You should be able to hear an engine pitch change when shifted into gear as long as your torque converter is working properly.

Engine RPM jumps around when moving in and out of gear yes. It will quickly increase revs when moving into a gear, but it increases the revs a bit more than I remember, as if its anticipating a load but ones not actually there? Kind of difficult to describe.

I've got auto enginuity hooked up, is there anything on there that I can monitor to help diagnose this?

Alright, I've got some more info.

When I was bleeding the HPOP after installing the engine, I didn't have the trans cooler lines hooked up to the radiator/cooler return and while cranking it sprayed trans fluid all over the place. This led me to believe that the pump was working fine.

Today I put a gauge on the test port and at idle in park I've got no pressure (should be +/- 50psi correct?). Would this be a tc issue, or an issue with the front pump (that I should take back to the shop that pulled it off to replace the tc bushing and front seal)?

Also removed the return line and it has no fluid flow at idle now.


I've read that the 6.0 and 6.4 TCs are interchangeable, with the exception of drilling the flex plate so I followed the 6.0 crank spacer machining directions.
