my 1972 benz with a 5.3 and 4l60e. car needs a tune because it throws every emission code, but car also throw code that reads shift solenoid B. car makes a ridiculous whining noise around 50mph+ and it has alot of shifting issues. now obviously car needs this to shift right but could this cause whining noise as well?
the rear end drips a little but makes no noise from 0-60 no matter how fast i get there, higher speeds just whine.... any clue?

ill throw some pics in cause ive never seen one with an ls1 before.
