I just got P0732, P0735, and P0775 codes on my 04 LS Premium sport. I changed out the solenoid a few months back and everything seemed to be fine until two days ago. In May, I replaced the solenoid, filter and fluid and everything seemed to be fine. From what I have researched (here and on the Google), the pressure issue could be electrical between the solenoid and the PCM. I have even seen suggestions that low fluid could be a culprit. The main issue I have is not having all the diagnostic tools for the transmission and would be "guessing" at solutions. I am trying to find a good local independent shop, not All Automatics Must Come Out! Any other thoughts?
