904 with Turbo Action shift kit, no 3rd

Sorry its been so long, but I finally have an update on the 904 situation. I have the valvebody out on my bench, and I had previously installed a MP shift improver and a Turbo Action Cheetah shift kit #17810.

The MP kit says remove the accumulator spring and put a blocker rod in to hold it down, and turn up the line pressure to max. **I did not increase the line pressure after installing the kit the first time.

The Turbo Action kit adds some plugs and a separator plate. I checked the 2-3 shift valve as BRONZEBEE mentioned and it was perfect. All the balls were also in the right places. The directions for the TA kit are hand drawn and terrible, and I cannot figure out if I installed everything right the first time: The kit shows to remove a spring and put a plug in its place for the 2-3 or 1-2 shift valve, and I cannot figure out which one. The plug only fits in the 2-3 hole and its loose, but the drawing shows it going in the 1-2 hole. ***I also left the spring in the first time.

I am not sure if these two issues could be causing my No-3rd issue, or if the kits are somehow conflicting. I want to get this figured out before I put the valvebody back in again. Thanks all.
