There's a problem in your MCV (Multiple Control Valve) circut. The MCV pump/valve supplies oil to the steering, brakes, TA, and transmission lube/cooling. Steering has priority, so when a problem develops, lube pressure is the first thing you lose, then TA lockup pressure, then power brakes. Since the low side of the TA uses a mechanical sprauge clutch instead of a hydraulic clutch pack like the high side, the tractor should downshift to the low side and keep moving when lockup pressure is lost, but since yours quits moving, it means your TA is out (this probably doesn't have anything to with your current problem). I'd suggest taking the tractor to a Case-IH dealer or someone else who really knows them, as it can take quite a bit of testing to track down a MCV problem. I saw your other post about swapping engines, that would be very easy to do while the tractor was split for a TA job.
