P0770 still throwing after new solenoids and new torque converter! Help!

Hi guys, I have a 2001 SR5 Auto 4WD and I got the dreaded P0770 CEL code and already pulled the trans and out In the three new small silver solenoids and a new torque converter and the code is still firing. Only two options left seem to be swap the valve body from a junkyard truck, or swap the whole transmission. Any thoughts on what may work to fix and stall the code? Also, does changing the fourth and fifth solenoid on the valve body help? Or perhaps cleaning the valve body? If so, who could clean it for me? Special mechanic or any trans shop? How hard is the valve body to pull and swap? It seems like a lot of springs fallout behind it when you pull it off the trans? Are they hard to put back in or super easy? Thanks for the help!

Did the OP ever get this figured out? Anyone/Op tried putting stock size tires back on clearing the code and driving for a period to c if the code would/wouldn't set again...
