I have an 04 pacifica, 3.5.
It started not shifting a couple days ago. I hooked up an obd2 scanner and got a OSS code a gear 2 code a transmission mil code. After a bunch of testing I replaced the output speed sensor. It ran normal. Next day it's having the same issues, it won't shift out of 1st the speedometer stays at 20 mph before it stopped shifting it would have a real hard downshift into first when coming to a stop. I'm at a loss, now. I'm thinking maybe the shift solenoid now? Any input is much appreciated.
