My turn... Driving today, doin around 50, no romp stompin in a couple days, going into the left turn to a light, braked slightly, downshifted to third... NO THIRD. braking harder down to second... NO SECOND. Stopping, down to first... NADA. Pushed myself across the road into a parking lot. Checked reverse... NO REVERSE. My day is quickly going to s***! Tow it home...
So I got it in the garage, did the self-diagnostic; came back with B; Line pressure solenoid valve circuit is short circuited or disconnected. Now that was done about 35-45 minutes after being shut off. I started it up , checked the gears, nothing. Then the last time I started it, tried reverse and it actually rolled back a smidge at idle, but nothing else. I did the SD test again and this time it came up OK, nevertheless, I still don't have ANY gears. Even parking gear is gone. If you try to put it in park, you get a gear grind, had to shut down in nuetral, turn off, then shift to park... w/ emergency brake on.
The part that sucks is that I called Pat at Level 10 today to ask about a transbrake. He said they were working on them, multiple requests for them... Go figure. They're testing them, told me to call back mid January. So, while I'm daydreaming about a transbrake for my baby, this s*** happens...
Anyway, I dropped the pan, clean as a whistle. Normal amount of crap on the magnet, not bad at all. I was concerned I lost my input shaft, which I may have for all I know. So the reading has begun. Calling L10 tomorrow.

Line pressure solenoid valve circuit measured 1.16 ohms.
