I contacted the service regarding a suspected breakdown of the automatic transmission in the Dodge Caravan. The master performed diagnostics not only of the automatic transmission, but also of the engine. I found a malfunction in the DZ sensor. That's it! He opened my eyes. And it was possible to get to the "repair" of a serviceable box.
I came for a complete replacement in the automatic transmission box. The service station has a special unit for this case. I note that the service station is clean, it is clear that they keep order. Polite craftsmen. I'll come back again.
