Tundra Dad

Hi all, I chose to join this forum because of my sons 2011 Tundra 4x4 with AB60E that I'm having issues with. It had a P2714 code which I replaced the F-Trim solenoid and now has a P0761. It won't shift past 3rd. I used to be able to clear it and get it to shift to 4th but it gotten worse & doesn't improve after clearing. I've changed the filter & flushed the fluid. Even disassembled, cleaned & rinstalled the valve body. I ordered a C solenoid and will replace that along with the output speed sensor. This will be my final attemps as this trans has over 400k. Maybe a TCM. It's flashing the Hi/Lo light sporadically. One thing I noticed that there were only 7 Check balls in the upper valve body & most if the diagrams I've seen have 8 check balls. Anyone else have pics of 7 or 8 in their valve bodies? I have alse removed, cleaned & checked all connectors associated with the transmission & tcm. If the sensors or TCM don't fix it, time for another transmission. Im open to Any tips & tricks to try before throwing in the towel. Thanks in advance.
