P0746 Pressure Control Solenoid A Performance or Stuck Off 2004 Toyota Sienna U151E

One day when I go into reverse I have a strong shock and vibration. The oil was very dark brown and I changed all the oil but the symptoms are the same. However, in drive it takes a while to start and then it is fine in the next gear. The code is P0771. Do I need to replace the valve body?

Have you considered changing the valve body, and the seals around the valve body?

I have a 2008 Toyota Highlander limited. Reading same code. Had the solenoid replaced, but the same code is still appearing and it still want shift properly into Drive, but yet it shifts properly in the other modes shifts properly , meaning I feel and hear the shifting gears when I shift but not in the (Drive) mode and it also want drive as it should. What's next?

you might have to check the wires and connector to the particular solenoid. Check the wire for resistance (ohm) and voltage if you could.

I also found 3 loose tiny ball bearings and no idea where they came from.

The second tape was just to secure the check valve, because one tape was not enough. It is important, because it controls the transmission fluid that passes there. For the 3 loose balls bearing, you’ll the repair manual for that, because those balls also allow and close the fluids pathways.

I will change the after market cv axles for OEM, I still have them, I will install new boots and see if this fix the problem, because mine didn’t have that shifting problem when I bought it, I didn’t pay attention but I think this appeared right after I replaced the OEM cv axles for the after market ones.
