Truck is an 05 explorer, v6, 4x4. Shifted perfect until the other day it randomly stopped going into 2nd and 5th gear. Rather than go into 2nd, it just keeps revving up until it goes straight to 3rd, then shifts to 4th and locks the converter. By this point the o/d light is blinking and it says "check transmission" in the odometer area. Besides skipping 2nd and not going into 5th, all other gears work normally. I scanned it and have 3 codes. P0732: gear 2 incorrect ratio, P0735: gear 5 incorrect ratio, and P0775: pressure control solenoid B. My first thought was the solenoid block. I ohmed out the whole thing using the pcm connector and F-37 cavity and everything came back within spec. My 2nd thought was a broken o/d band. However I adjusted it by the book (10 ft-lbs, back out 2 full turns) and it torqued down. So that tells me it's not broke. The adjuster seems to be in just about the same position as before the adjustment. I took it for a drive after the adjustment and there is no change in transmission function and I have the same codes. What would be my next step? Could a mechanical failure of PCS B be to blame? If so, wouldn't that make all the other gears act incorrectly too? I noticed in my ATSG book that 2nd and 5th gears use variable pressure from PCS B, whereas all other forward gears have lower presure.
