I purchased the Mishimoto Trans bypass valve for my 2017 5.7L 6 speed. I was under the impression it was supposed to cool the trans temps by like 20 to 30 degrees. I removed the thermostat and installed the bypass valve per the instructions. My truck trans now runs maybe 10 degrees cooler. I guess maybe my trans never ran "hot" maybe 180 running down the highway. But sitting at idle in the summer it gets around 190 200 sometimes.

I installed the part on the right- the bypass valve right?

Am i missing something?
Yes it has a 6 speed - Canadian truck. Express poor mans package.
Trans fluid changed maybe 10k miles ago. And it had been previously changed before that. Truck has 82k miles. Changed Fluid to Redline C+ ATF.
