High transfer temp after tru cool max install

[Hefel86]

I just installed the cooler and my transcript temp stayed at a constant 190-200 just driving around. Not sure what the issue is. My truck looks to already have a hayden transmission cooler in the location I wanted to install(right be hind the grill on the center supports per diselsites instructions) the so I mounted my tru cool below the hayden in the gap on the bumper between the license plate. The line exiting the hayden cool and entering the tru cool is warm but my line leaving the tru cool and connecting to the trans return line is cold. I figured I'd be cooling too much with the added cooler but I have the complete opposite issue. Any one have any ideas what the problem is?

Pull the line coming off the trucool and see if you are getting fluid. That will make sure it is flowing through it.

you might have too much restriction. the pump may not be able to push the fluid thru two coolers

Well I removed the hayden cooler and placed the tru cool in its spot plus it's in serious with the stock cooler... When I moved the tru cool, it was full so I know fluid made it way thru. After removing the hayden and leaving the true cool I took the same trip which consists of 26 miles and a good 7 mile 5% grade and I hit 210 half way up the grade. This thing is driving me nuts. When I went to the desert last week pulling the toy hauler I was hitting these temps how am I hitting these temps un loaded?

Remove the trucool and see if it still does it? Maybe there's something wrong with it, some blockage, or something?

Not saying it is for certain, but if I am reading correctly, there's now only been issues with the trucool installed, correct?

[Hefel86]

Well I was thinking do that but then I would be running only the stock cooler and before the tru cool I also had the Hayden in line. I also installed my beans chip at the same time of the cooler install. But I wouldn't think that would cause the issue. I'm thinking about trying the flow test in the am and see what happens. Am I correct that if I pull my return line off my cooler I should get 1 quart in 15 seconds?

Something is wrong if you need that much cooling. With just the stock and tru cool I dont break 160 pulling steep grades in the summer.

[Hefel86]

I know! I was sitting reading all the good reviews and temps ppl are running and I'm like wth? I'm hoping its just a restriction and maybe a flush will fix it. I don't think I hooked the cooler up wrong... Kind of dummy proof isn't it? I just tapped into the lines that the Hayden cooler was using and those lines trace back to the main return line and a line coming from the Oem cooler

what about you bypass tube? if it is bypassing you would steadily get worse

[Hefel86]

I'm unsure of the by pass tube. I know the tru cool I ordered came with out because I gave them year of my truck (2000) and diesel site said I didn't need it.does my nome cooler have one? Where do I check?
