searched but unclear on tranny cooler install. need help.

to start with, i know there are plenty of threads about this, but all was unclear as to my actual questions, i have already searched and read most. so here goes.

well the temps down here in GA keep geting warmer and warmer. I have a Hayden Ultra-Cool 405 trans-cooler. last year around this time my radiator busted, and got anti-freeze all in my tranny and killed it, so i rebuilt it, and picked this up, but was unsure of how install it. so its just been sitting around collecting dust. i'm wanting to route it so it doesnt go through the radiator but would that be a good idea?? my truck has the optional small external trans cooler also , so should i keep that there and just connect this in line?? i want to know the BEST way to do it. plan to do it this weekend. also what lines are what far as feed line, return line. ???im guessing the line running from the tranny to the external cooler is the feed, and line running from the radiator to the tranny is the return????


any help would be greatly appreciated!

if not mistaken the top line is the feed bottom is the return, just put the cooler inline.. you can use the smaller cooler also it wont hurt nothing just give it alittle extra cooling, i use 2 45s inline with each other ;)

I got this same question, so I went to a Trans Expert and gave me a fast non tech answer. Water will always be a beter cooler than air. Understanding that, the temp at the trans fluid is almost always higher than the Engine oil temp (explosions and flames are handle inside the engine and not inside the trans) so the water will be better to absorb the heat of the trans fluid that the air by it self. After lowering the temps with water you can aid warever HD A/A fluid cooler/s as long as you dont restring pressure that much.

I was thinking that the radiator trans cooler was there to take the trans fluid to working temp fast, and for cold weathers, but this Trans expert told me I was wrong and under the influence of a lot of urban legends.

I live in a place where the cold climate temp is 32* Celcius, and I use the radiator trans cooler and then 2 HD a to a coolers and I hold the temps to 185*F and on some passes I can see 195F but never pass that temp.

Hope it makes sense.......regards.

is there a "how to install a tranny cooler" for Dummies book? lol i need one, so from what ive gathered, im going to have to keep it ran through the radiator? i sure hope that thing doesnt bust again cause if it does i dont know what im gona do. im no longer at the tech college i was when i rebuilt the tranny last year...

bro its not that hard, just disconnect the tranny lines from the radiator, use some good hose and clamp each end parallel to the cooler, i didnt cut the ends off the tranny line i was able to fit the hose over the ends ..

i would never run a tranny line through the radiator ever again for the simple fact its happened to me!!

Sure thing, I can go into further detail if the pics don't quite make sense

Top line is return, not the bottom.

well thanks guys for trying to help, i just decided for now till im 110% sure of whats what and IF its safe to run with it without going through the radiator to just put it in place of the factory one. took the bottom bracket that held the factory one and trimmed it and fliped it so itd still have the hole for the air temp sensor thingie, and made brackets for the top, just unhooked the factory one and slid the hose over the lines and hooked it up, seems to run cooler than before but i only drove it for 30 minutes and it didnt even get to 150, and its around 90 degrees out.
