B&M Transmission Cooler Install Question

On my transmission cooler lines they have this weird connecter piece on the hose how would I go about taking this off so I can tap into this line to pipe into my transmission cooler.

That is a crimped high pressure fitting onto the line, there is no taking that off and reinstalling it so don't pull or pry on that or it might leak in the future. You will want to tap into your lines elsewhere. Where do the instructions say to tap into?

Instructions say to hook up cooler to transmission lines its very non descriptive. Ive also been hearing to just cut it off with an angle grinder

Cut the soft lines and use hose barb connectors.

Im just weighing out my options right now but if I do decide to take the route of cutting off that crimp how would one go about taking it off the nipple thing that comes out of the radiator side, would i need to cut the crimp off while its still attached to that line or what??

Upon further investigation my internet mechanic senses are telling me to cut the crimps I have borrowed a dremel from a friend so I wont be under the jeep with a ridiculously large angle grinder possibly cutting the actual line...So the technique seems to be cut a notch in the crimp and take a large screwdriver and pry the crimp open from there to reduce the risk of cutting the hard line. Ill post some pics up on my progress tomorrow

What are you talking about doing? Don't cut through a crimp. What good thing could possibly happen? You end up with one end that has a cut open crimp, and the other end has a stretched out rubber hose. What do you do with either end, other than head to the store to buy new lines?

Either cut the rubber a few inches from the crimp and use hose barbs and clamps, or make your life hard and cut the metal tubing then adapt hoses and clamps on that, but since they won't have barbs they are more likely to blow off and leave you stranded with no fluid.

By the way, I suggest you figure out which line is coming out of the radiator, and tap the cooler into that. I could be talked into either strategy, but that one makes the most sense to me.

In that case, the hot or cold fluid would get closer to the radiator temp, then your aftermarket cooler takes it down a little more before returning it.

The other way around, you cool the fluid in your aftermarket cooler, then send it into the radiator to probably heat it back up.

Cooler before or after radiator is a different debate. Personally, my cooler is before, but it doesn't change original question. Why anything other than cutting the soft line is an option I don't understand.

So theres 2 crimps on both ends of the soft lines, I would cut those 2 crimps remove the old hose then use the new hose that the B&M Cooler comes with and their hose clamps. This is much easier than cutting into the hard line because I would need to buy extra parts from the store to connect the hoses. And Im not cutting into the soft line before the crimps because that would cause a very harsh angle if I do mate up the 2 ends also I would need to go out the the store to get 2 barbed connectors...The method that people have been using and had much success with is cutting the 2 crimps, trashing the old hose and using the BRAND NEW soft oil transmission lines and the PROVIDED hose clamps. Here is the EXACT model I have https://www.amazon.com/70268-SuperCo...mission+cooler and Once I do cut off the crimps there is well a hard line underneath let me send you over to this link http://www.s10forum.com/forum/f107/r...-fixed-343472/ and look at post number #172 here: http://www.s10forum.com/forum/f107/r...-fixed-343472/

I am going to be hooking up the transmission lines after the fluid gets cool through the radiator seems to be the most logical

I'm too tired to sort through all that. I've had no problem cutting in to soft line with a little bit of space on either end and putting in barbed connections. Feels to me like you are making this much harder than this needs to be.

It depends what your approach is. One version is cooler is always better. Second is there is a "right" temp for transmission fluid. Opinions vary.

Cutting the crimps and cutting the soft line are really the same thing but if I cut my soft lines I will need to search for something connect the 2 soft lines but cutting a slot in the 2 crimps then prying them open will take no more than 5 minutes then drop the old hose out and replace the old line with the new line from this kit and add 2 hose clamps per end to ensure more security then im done and i dont have to run to the store again and ill be efficient in using what is provided in the kit. Also take a look at this video to get a better idea of whats going to be going on https://youtu.be/ZCyFgrZfOF0?t=4m10s

In your link they have both ports on the aux cooler facing down. They should be facing to the side (input on the bottom) or facing up and it doesn't matter which port is the input.
I also put the aux cooler before the radiator...
