Symptom: does not advance the truck, but if it has reverse

DTC's: P0720 P0715 P1784 P1782

turn on and put the transmission in "Drive" the truck Three times to change the "D" R "lever and vice versa loses all force in" D ", it only has strength in reverse; We have already cleaned the transmission sensors (which came out too black), replaced the oil, filter and solenoid package, I hope someone can advise me ... you have to lower the box and replace the masterkit or is it only electronic failure? In advance I appreciate your collaborations.

It has more mechanical failure face than electronical friend, it is like the end of the electrovalves.

But the electrovalves were already replaced, I already have 3 solenoid packages in good condition that we put and follow the same problem ... or do you think it is from the transmission valve body ????
