If I start out in 2nd, it stays in 2nd. If I start in 1st, it will shift 1st to 2nd, then stay there. I normally do the shifter thing where you lock it into 2nd for longer to get the rpms up before shifting into 3rd. It will not go into 3rd regardless.

The 1st-2nd shift is on time.

I did read about the pressure testing thing...I would need to either buy the tool, or make the tool via the instructions I downloaded...banjo bolt, gage, etc.

Right now, the valve body is sitting on my workbench. I will be giving it a going over this evening. Hopefully, something obvious.
