There is a distinct difference between slipping and being unlocked. Slipping implies that the lock up clutch in the converter isn't holding and is spinning and burning itself out. Being unlocked means the lock up clutch in the converter is disengaged and you are running on fluid coupling instead, which as you know, will bring temps up.
I'm not sure how the bullydog is programmed. You could probably have them keep the converter locked up in 2nd/3rd gear. Stupid question but was tow/haul on? Not saying you don't need a cooler. Just curiosity.

I dont have tow haul with my 4 spd but od was off.
But before this gets derailed too far all I really need now is tips/pics on the actual install if possible. Ive done plently of towing/parts installs/fabrication/etc to figure it all out just wanted to see what others have done. Thanks.

My personal preference is hard line but that's a pain. If you can find some silicone hose that can withstand the pressure and heat and is oil rated, I don't see why you can't mount the cooler where it gets the best air flow and plumb in the lines. Make sure they are large enough to allow proper flow. I've seen several factory vehicles using nothing but a hose clamp or spring clamp to hold the hose on.

Here's a pic of my factory cooler on a 2010 4.6L.
The two hard lines run back to the tranny, and at the upper right, the line leads to a cooler that's part of the radiator. I'm assuming you have that, so your problem is that you have to cut factory hard lines to plumb in your cooler.
On my old tacoma, I had a stacked plate hayden cooler, which was easy to plumb in between the factory return line from the primary radiator cooler.
Just make sure you have your cooler on the return fluid line. I don't know what the fatory standard cooler looks like, but if you have any rubber lines, I'd use two 90 elbows in that section before I cut hardline.

Thanks. Mine looks just like your except for no cooler lol. Just hard line where your cooler is basicaly. See that hard line on the left side of your cooler coming out of the quick disconnect? Thats what I was looking for - something with the disconnect fitting to a hose...this way I wouldnt be cutting anything.
