4L80E no first or 4'th gear
 

Solenoid "A" works and is sealing good.
All valves can move in the VB.
Wireing is OK.



AFL problems maybe?

or bad pressure switch Nbr 4?



Dont know if it has something to do with the checkball discussed in this thread https://ls1tech.com/forums/automatic...-hd-3-kit.html or something else is wrong
