I had the Tru-Cool Tranny cooler installed....

I'm in south Florida and have yet to hit the 150 deg. mark without pulling a trailer in 95 degree heat. As for the part number I'll have to look it up but I think it was the largest cooler that they made, something like 40,000 btu.

Just looked it up it's Tru-Cool part #4739 with the cold weather pypass and #4739-1 without the cold weather bypass. If you don't have alot of cold weather you don't need the thermal bypass. Both are 40,000 GVW and 45,000 btu. Just be sure to bypass the radiator when you install.

Here's a couple pics I snapped w/ my phone (sorry about quality, but you'll get the impression of what/where it goes)....After looking at a couple other sites this looks like about the most common spot for installation....and yes, it is the exact same part number H2illbilly posted above...mine was the tru cool 4739....

Got it. Thanks all! I am going to get a quote from AAMCO to install it.

The higher temp is likely due to the bypass (I'm installing the same as I'm in North Dakota) - there is a thermostat in there and that's likely "leveling" the tranny fluid temps. To be honest - 175F constant is a great temp. Not too cold and not too warm. Wish it was more like 150F or 160F, but that's not bad.

On another note, just got mine (w/bypass) yesterday. Hoping to get it installed this weekend.

how difficult was this to install?

on the link posted, is there anything else required besides whats on that page?

Wow, I'd better get one huh? I just got an 06' H2 and was driving through some mountains this weekend. The outside temp was 100 here in Southern California, and I noticed the tranny hit 200 while climbing the hills, but you guys never hit 175? Do you think I have a problem or just need to install a tranny cooler?
