Based on my similar experience with the AW70/71 (family) of transmissions in my '84 244GL, yes, that is your problem.
One of the valve balls, C5, is probably worn and sticks at one side on its run through the valve channel wherein it operates.
Do you also find a late 1-2 upshift, like the car is holding onto first gears until the last moment? This is the classic symptom. The ball sticks until fluid pressure pops it out, giving you the rough upshift.
On my car, it happened both ways until the fluid was warm.
the FAQ covers this repair, and the valve ball controllers are available at your dealer.
