2-1 rough downshift, fault code P1775...
I am trying to figure out what to change next on my 2000 Grand Caravan.
Two days ago, the tranny was "clunking" when coming to a stop... like a rough 2-1 downshift. Additionally, when putting it into drive from reverse, there is a hesitation. Then, on day two, ck engine light on.
Took it in for tranny service- fluid/filter changed, chrysler fluid put in. STILL had the same problems. Went over to Autozone to check engine light fault codes. The first fault code was P1775, Transmission system MIL fault. There were two other codes, related to the first.Deleted codes, and engine light went off, all trouble stopped. Person who worked in store thought maybe after filter change, I needed a reset. All was fine for a few hours, then trouble started again, engine light back on. Original code explained the problem as open/short circuit condition and listed probably causes as 1. poor electrical connection or 2. failed pressure sensor. Person in store also mentioned solenoid or relay as cause for poor connection.
I cleaned the connectors with no luck. What to change next????????
