My nephew has a 2005, the heat exchanger leaked antifreeze into his transmission! He is getting the tranny rebuilt and wants to install a better cooler and delete the heat exchanger ($1000.00 for a new one) thoughts please!

I have been told that the exchanger is good for the transmission in part because it helps get it up to operating temperature quicker. It also works to dump extra heat into the engine when the transmission is getting hot.

I would keep it. A 1000 dollar heat exchanger is cheaper than a 4k trans. I cant believe that its that much

I would search local wrecking yards for a replacement. This is the first one that I have heard of failing.

Thank you all very much! I agree with you and really wondered how many ever fail. Thanks again!

I have heard of quite a few failing just like this one, not sure there is a better fix thou.

Really? Hm, How about something like this? http://www.grainger.com/product/BELL-GOSSETT-Heat-Exchanger-2NXR5?s_pp=false&picUrl=//static.grainger.com/rp/s/is/image/Grainger/2NXP9_AS01?$smthumb$

Holy crap that is not cheap!!!

The Grainger one looks interesting, my nephew says that a factory one is $1000.00

I found one for 700. Its called a torque convertor cooler

Here is another one slightly less expensive: http://www.grainger.com/product/BELL-GOSSETT-Heat-Exchanger-2NXR2?s_pp=false&picUrl=//static.grainger.com/rp/s/is/image/Grainger/2NXP9_AS01?$smthumb$

Check this out. Buy it from Cummins.

There ya go!
