A604 Archives - Transmission Digest
Outta Sight!

We’ve all had to chase intermittent vehicle issues. What makes them so challenging is that you can’t fix what you can’t see. Sure enough, it always seems that the concern disappears when you’re trying to diagnose the issue in your bay.

This story is a similar case. We were diagnosing a 2002 Dodge Grand Caravan with a 604 transmission and 3.8L engine. Six months prior, the vehicle owner contacted us and said that the transmission would not shift and was starting off in 2nd gear. By the symptom description, the unit was likely going into failsafe mode. We scheduled an appointment, but the customer was a no-show.
