A518/46RH transgo TFOD-HD2 shift kit install

Thanks for doing this, I'll be following closely. My A500 is on the bench and I just pulled my valve body, just need to order the transgo kit.
I have a question for you too. After pulling my valve body, I removed the accumulator piston spring and the piston. I was surprised to see there wasn't another smaller spring under the piston. The YouTube video I've been watching shows the big spring on top and a smaller one under. Does yours have two springs? Don't know if I'm missing a part or if my tranny never had one.
Can anyone she'd light on this?
