Hello,

This codes comes up for one of two things, first the solenoid goes bad which you already replace the second is the seal for the clutch pack that changes the gears goes out not holding pressure which causes the clutches to slip. How was the condition of the fluid, burnt?

Please let us know

Cheers, Ken

Clear the codes again and drive it for a bit to see what happens. Try a capacitor discharge by removing the negative battery cable from the battery and touching it to the positive terminal. Leave it there for 10 minutes.
