Turbo 350 NP205 Leak

[fleetmitch]

To follow up, can the leakage problem from Turbo 350 to transfer case also cause downshift problems in the tranny? Admittedly, my trans fluid level got low before I found that it was leaking into the transfer case. But now my transmission won't downshift to first gear at a stop sign. Otherwise, it shifts fine - either manually or if when stopped, I move the lever to first and then back to drive prior to pulling away from the stop sign. I pulled the pan and valve body, and found a very small amount of metal dust (we did a rebuild just a year ago) in the pan and everything in the valve body worked OK. We replaced the detent cable, and even tried adjusting it all the way in. Can there be a pressure issue, whereby not enough pressure (due to bad seals) that the tranny won't downshift?
