Got the transmission valve body opened again, it had same error.
Filled new transmission oil a week back. It was pretty bad this time as well.
Found new (kabli/used) soleniods, will fill in new fluid again and also asked to change the filter as well.
It is decided to change the oil after a few months again.
Could this new fluid getting bad means there is something major or just solenoid and filter change would be fine?
I am not interested in flushing the transmission with any flushing fuild, Max I would do is flush using a new transmission even if means doing it twice right now. I mean use two new fluids one for flushing/draining and one for refilling.
