Low-speed "clunk" 1-2 shift, A-904

JohnRR said

Just to clarify the NORMAL position of the front band is RELEASED , the front servo is SPRING LOADED in the released position, it uses Fluid PRESSURE to APPLY the band , on the 2-3 shift the pressure is removed from the apply port and the spring in the apply servo releases the band naturally , it's not held open by fluid pressure .

That is incorrect. I'm sorry to say it that way, but there is no way around it. It is true that the servo is spring loaded in the released position. However, while in second and third gears, it is moved by hydraulic pressure. Second gear applies it, third gear uses pressure to counteract the apply pressure. This allows full pressure for apply to be already in place if a "kickdown" event occurs.
