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

[kchummer]

Had it installed the last week w/ the bypass and am happy but have a few questions for others that have put on an oversized cooler....I was curious if it's supposed to run a whole lot cooler under NO load compared to the normal OEM cooler?? It never gets over 175 but neither did my OEM, but I thought I'd read where some of you southerners that are in scorching temps said yours never was over the 150 degree mark....just curious, please respond with what kind of temps yours runs w/o pulling anything w/ an aftermarket tranny cooler....I guess I'm just happy with the piece of mind that I wont have the pepto bismol effect to worry about...lol...thanks for replys!

Which one did you get? I am looking to do this also and wasn't sure which part number to get.
Thanks

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....

Here's link for the exact part and place I ordered it

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?

[jmanley]

Can someone post the routing of the lines from the radiator (and show how the radiator is handled) removed and now to the cooler and then routed back? I see lots of pix of the cooler itself, but not any of the hose routing and/or many of the radiator connections.

I would say you're temp is normal....it was just hanging around the same temp as the motor....I think when it becomes a problem is when your towing and temps get above 250-275 range.
