Cause:
Breakage or collapse of the channel plate/lower cover checkball spring.
Correction:
Replace the spring with this direct replacement version.
The channel plate/lower cover checkball and spring in the various VW/Audi 01M, 01N and 01P units aid in controlling solenoid regulator pressure. When the spring breaks or collapses, proper fluid control is not maintained, resulting in 2-3 and 3-2 shift complaints. The Sonnax checkball springs restore proper fluid control.
