The place that installed my tranny and cooler bypassed the radiator all together for the cooler that they installed in front of the radiator, which is the size of a post it stamp. I now have a 28000 gvw tru cool cooler about 3 times the size I want to install. I live in Florida and dont see temps below 30 degrees to often in the winter. Is it neccessary to use the radiator along with the trans cooler. What are the bennefits or reprocutions of not having the radiator as part of the tranny cooling system. I know that the fluid should flow from the tranny, to the radiator, to the cooler and back to the tranny by reading other posts.

 

Like i said in another post, i dont know a whole lot about the trannys and such. But i think if you ran it to the Radiator it would warm up to operating temps faster, and then to your aux tranny cooler which would cool it off if it were to get hot.
But thats just what i think...

I check my temps alot with my laptop, usually i see around 180* during the summer days. Night times it is usually about 150* or there about. I towed about 9klbs of sand the other night and my temps never got over 198*.

 

After talking to the guy that did the initial work, I dont know if it will be an option for me to use the radiator because he says I could still have metal shavings in the radiator from my old transmission when it blew out. Will I be ok not to use the radiator and just the after market cooler, will this cause it to run too cool come winter time, and will it cause it to be less effective in the summer time?

 

its better to run it through the radiator and the cooler. just put the fittings on the radiator, hook a rubber hose up to the top line, and run a couple of cans of brake cleaner through. when it comes out clear the radiator is clean. when i did mine i stuck the straw in the hose and wrapped a wrag around to keep it from coming back out.

 

that sounds like a good idea roach!

i would surely try that Orlando. just change your fluid and filter often and you should be fine..

 

I have the front grill assembly off of the truck and have fabricated some brackets to mount the larger cooler; I dont want to use the zip ties. I had to remove a horizontal brace for the cooler to fit and I will try and flush the radiator as you said and re-route the hoses.

 

I agree...if you have access to an air compressor, spray a bunch of brakleen through the cooler and give it a good shot with some compressed air also.

 

mine is bypassed. i have a huge cooler and a fan for my trans cooler. no issues at all. going thru the rad is warmer then what the cooler alone is. i would rather have my trans operate at 150 then 200. think it wont cool off as much if your going thru the rad. if you have a small stall not a biggie but a large stall you should bypass it

 

Everythings back together, I fabbed up some brackets that came with the kit and the cooler is in there pretty good; no leaks and the trans fluid is topped off. Not gonna believe this though, I was drilling the last hole through a mounting bracket and into some metal near the hood release and when the bit broke through the last bit of metal, it slammed into and through the condensor I now have this hissing noise coming from the hole in the condensor. Does this mean the condensor is shot, can it be patched?

 

replace it!!
