Default 2004 ram 2500 auto not going into 1st gear

I have 2004 ram 2500 5.9 Cummings
I changed governor pressure solenoid, accumalator spring and transducer. I adjusted bands inside transmission, hand snugged (no torque wrench) and backed off 3 complete turns, I did not adjust bands on outside but now my not shifting into 2nd and 3rd is fine but it does not start in first gear unless I drop into 1st manually. I felt like my bands were looser after adjusting. Any ideas?

Update: I now have p0868 line pressure code but I didn't have a code even before I changed solenoid and transducer, I did not change the speed sensor. Can loose rear bands cause line pressure issue?

Thanks in advance

Default Specs found

For anyone else wondering the specs, I found this. I'm still not sure what transmission I have?

46 never came behind the diesel. Gotta be a 47, or 48.

Supposedly, the 1st gear band isn't used for 1st gear when the shifter is in drive.... it only engages in manual first. You already changed the parts that I would suspect first..... No idea if the output speed sensor would play a role there.

Part number comes back as a 48RE. Which is what I expected.

Need to have pressures tested, and see if they agree with what the electronics are telling the PCM.

And yep, moving this to Third Gen Ram section.
