Trans cooler upgrade

Hey guys,
Have a 2001 f350 w/ 205k miles and a auto transmission.Was talking to another stroker the other day and he mentioned that you can take out your old transmission cooler and put one in for a 2004 truck to get better cooling for the trans. He said the difference was 7 passes for the old and 27 passes for the new. Has anyone done this and is it effective? My transmission's warranty just expired and I want to make this trans last as long as possible. Thanks.

Yes that is a common "upgrade." If you buy a used one make sure you flush it and make sure it is clean before you put it on. Also it can be from any 6.0 truck doesn't have to be 2004 only.

Yep - one of the best things I did

Top is the 6.0L, 31-row, bottom stock 9-row.

You'll need some 1/2" hose and some adapters that go from 1/2" to 3/8"(stock tranny line size). Bolts in the same place as the stock cooler. Not hard to do, but it is time consuming. BUT...the results are very good. I have a 230* gauge for my tranny. Before I upgraded, I could peg that gauge pulling a grade in the summer. After, not even close!

It's a upgrade your tranny will love, it's a direct fit just have too spend sometime getting the bumper,grill,etc... out of the way. I don't have a temp gauge yet but compared too the stock size over the 6.0L as seen in the post before mine you can see the difference.

+1 on it being a great mod, down here in Texas in 100 degree + weather during the summer my temps would be about 190-195 and now they are about 40 degrees cooler.
