Changing Tranny Cooler for 6.0L cooler

[SuperCrutyPS]

I have a 7.3L with the 9-row tranny cooler. Sometimes, I've had temps up in the 210-250 range when I tow my 5th wheel. I'd feel more comfortable with them lower. I bought a 6.0L tranny cooler, the hoses, the adapter fittings, hose clamps.

I plan on assembling the 6.0L cooler with the hoses, etc.

Now for my questions:

• How much of the front end do I need to take off to get this changed?
• Any pointers on how to get the old one out?
• Because the fittings are on the bottom of the new cooler, will I have air trapped in the top of the cooler by just hooking it up and let the tranny push fluid in?
• If so, should I fill it, plug the hoses and then just pull the plugs and attach to the metal lines, which might allow air in, but in minimal amounts?

I am open to any advice, pointers, tips or tricks from anyone who may have done this already......Thanks in advance!

just posted this up tonight: Tranny Heat Issues???

you will need to take off the latch in order to take out and put in the 6.0L cooler... make sure you mark it with a sharpie so you know exactly how it goes on later....
also lossen the radiator so that you have more room to get your hand in their... the stock cooler is a PITA to take off.. esp the lines... all i did was cut them so i could get it out...

are you changing the fluid at the same time? if not i would highly suggest it... take off the pan and put a new filter on it too.... if you want even better cooling add a larger pan as well... total with my 6.0L cooler, pan and secondary cooler i added 5gal of Amsoil ATF....

let me know if you have any other questions

EDIT: to get the air out dont plug in the return line... put it to a bucket and turn on your truck and let it fill up with fluid... then plug it back in... top off the fluid and your done

they dont need to be changed... but the 6.0L cooler uses a different size line so you just need some fittings to make it fit....

Good write up Raul. Thanks for the pointers and information.

I hadn't thought about changing the fluid or the filter, but I can see that it's a good idea. Not having fluid in the there would help get the new cooler in there. I'll have to consider that.

yah its def a good idea... you dont want old fluid clogging up the new cooler... if it does your screwed..... if you do that then i recommend changing the fluid first and doing a complete flush... then install the cooler so you know only clean fluid goes in....

its pretty simple just requires some time and some extra hands
