2006 Dodge Durango with the following codes: p0841 p0876????

Question

The car would not move at all and we were told that the transmission needed replaced. I dropped the tranny pan and changed both filters. When I filled up the tranny with fluid I added a bottle of Lucas tranny fix then topped it off. It would then move and I took it down the road to test it. There was an issue with shifting into overdrive, but at least it would move. Today I took it out and had to turn back when drive started to give out causing me to use 1 st and 2 nd gear to get home. Now it is back to not working at all. I am getting the catch all code p0700 plus p0562 and p0841 (pressure sensor switch A )and p0876 (pressure sensor switch D ). Is the tranny shot, or is there some replaceable sensor/switch that I can swap out??

Answer 1

This is internal transmission mechanical condition what happens is the snap ring on the reverse carrier moves out of place, Your transmission has a loss of prime. the pressure would be low, good try with the lucas. the only fix is to replace the transmission either a used or rebuilt.
