Hello, I know this has been asked before I have done everything I can think of from checking and cleaning the govenor, to checking to make sure the throttle valve isn't stuck while I was taking the valve body off I noticed what looks to be a crack in the 1-2 accumulator housing right where the tube from the oil pump enters. My symptoms are I have park, and reverse. It wont shift out first at all no matter how fast I go. Was driving up a hill on the highway cruising fin when there was a traffic jam I had to stop and when I went to accelerate it hasn't shifted since..

The oil is dirty in the pan was real dirty even though I just changed it 5 months ago pics posted of the crack and my oil. Would appreciate any input thanks alot!

 

You first need to obtain a line pressure gauge an observe the line pressure readings during the issue/ occurrence of the problem.

More than likely, YES you have a circuit leaking enough to interfere with the 1-2 shift.
But the circuits that have a cross-leak/ are leaking need to be confirmed.

Yes the color and metallic consistency of the ATF indicates problems/ wear and tear.
