P0340 is related to the CMP-Camshaft position sensor not the trans.
Check head space on the sensor and pickup, check the wiring and connections.
For the belt squealing, check the belt tension. Also, remove the belt and check the bearings on the accessories by spinning them by hand with the belt off. They should spin freely and make no noise.
What do you mean by "it behaves badly in wet weather"?
