what ya think about this setup
 
I've used the line pressure booster, seemed to firm up the shifts some. Every once in a while it would hold the 5th to 6th gear shift. Wasn't often, maybe that's what the spring is for. I was tuned and could still get low end torque converter shutter.

I haven't run the thermal bypass, but it seems it drops the overall temp about 30 degrees.

I've never been able to find out if the 19-present vb is improved or still has the cross leak issues.
 
vid did say not to use the line press kit with a tuned trans tho..couldve een the issue...its comin and i wont be doing the spring..so if i get no code gtg...
 
Could have been. I was just using a simple smarty Jr back in the day and idk if it played with the trans tuning at all.

I truly think the 3:42 gears in the 13-18 model years and early lock up tuning increased chances of the leaks in the valvebody. as well, but that's just an assumption and you you know what that means.
