So last week my truck started shifting weird and the next day it wouldn't shift from 2nd to 3rd without jumping around(it would shift into third, back to first, back to 3rd) and then would the transmission would go into limp mode. The code P0756 came up so I dropped the pan, changed solenoid B, fluid and filter and went for a test drive. It shifted at higher rpms in 1st then it was normal and shifted up to third and wouldn't shift again. I continued driving it hoping it would get better but now its back to square 1. Any suggestions as to what I should replace? The CEL came on again this afternoon and its saying the same code. The main thing that baffles me is that once it goes into limp mode then it shifts like a new truck(except no OD), and prior to it doing this the transmission never slipped or gave me troubles.
