How many guys bypassed the stock radiator cooler and just run the aftermarket cooler? Any real advantages or disadvantages?

I did it but only because I HAD to. I have a m6 radiator so I dunno what the difference would be bypass/ no bypass

I'm running just the aftermarket cooler. I originially had the lines running through the stock cooler and the aftermarket cooler. I was seeing 180* tranny temps in 40* winter weather. Since I switched the lines to run through just the aftermarket cooler, I'm seeing 180*-190* in 90* summer heat.

Any more inputs on this? I will be doing an aftermarket tranny cooler in the next few days and don't know for sure how I should do it.

i run it into the radiator and then into the after market cooler. i did it this way on my truck and it seemed to keep it cooler.

You will get people from both sides of the isle , I have done it both ways without any issues, Cooler only does from my experince run cooler in the summer. The exception may be if you live in a very very harsh cold climate ,

I agree, if you live on the Arctic Circle, keep the radiator in the loop, since its function is to warm the fluid to radiator temps. If you live a little closer to the equator (such as the U.S.) take it out of the loop, since its function is to warm the fluid. Think about it, do you want your fluid to run at radiator temps? If so, keep it in.

Awesome, I think I will bypass the stock cooler in the radiator then. How did you guys bypass the radiator? Did you use that converter thing with the female and male threads on it that came with the cooler or did you just cute the metal line and slide the rubber hose over it and clamp it?

This is what I am talking about in the post above. I got this weird adapter thing. Do I use this for the feed side if I am bypassing the oem radiator cooler completely?

Same here...I just got a pretty good sized tranny cooler (about 36,000lbs rating I think) and bypassed the radiator and it cools FAR better. What you have to remember is that the factory radiator only has ONE trans cooler coil running through it and especially in warm weather climates with a converter that stalls any higher than stock it's just not enough cooling capacity for your tranny fluid.

Im just running an external cooler on my'n...I dont have a temp guage to monitor temps so i dont know if there is any difference on my car..One thing to remember, when you bypass the radiator you eliminate the chance of ever having coolant mix with your transmission fluid. Which is one of the reasons why i would rather just run an external cooler...

I would also like to know if you just cut the lines and clamp on some hoses?

Yes you can do this. There is not a lot of pressure in the tranny lines. If you do CUT the metal lines just be sure to flare the ends with a flaring tool. I simply unbolted the lines off of the radiator and slid the nut back, since the factory lines are flared where they go into the radiator.

I unbolted the lines going into the radiator and slide the nut back and clamped as well. Seems to be working fine so far.
