I searched for a product review thread and came up with nothing. I found this thread started by blk7gxn : https://gbodyforum.com/threads/why-isnt-there-a-review-section.83825/ and I get it, I guess.

I want to offer a review of an an amazing part I bought over the winter and it has worked beyond my expectations. A TruCool 40K trans cooler.


I was directed to it by my converter guy so I tried one. I found one on ebay for $100 or so. And after a couple of years of battling trans temps being in the 180-190 range cruising and 200-205 pulling the trailer last year, I'm done with that now. I bought the 40K LPD47391. It is an easy fit in front of the radiator. Maybe if I had AC it might be tight, but it's between the rad and 4" intercooler and IT'S AMAZING! I can't get my trans over 165 now, except at the track. Previously I would make 50 degrees per run, but now only 35. The most I've seen at the track ion a full 1/4 mile pass is 185. Another upside is that it cools back down way quicker than previously. And I don't run any fans on it other than the trans fans. I'd recommend the 32K or 40K to anyone with a minorly slippery converter.

p.s. If anyone else reviews a different product here, then I'll change the name of thread to 'Product Review'. And I thought it would be good if we tried to keep it to positive reviews rather than dumping on a product or vendor.

A couple of ads show it to be manufactured in Canada.
I'll take that over China, even if it costs more.

They are a division of Dana, as in the Dana 60 and 80 people. I can't remember where mine came from, but was a genuine. There a ton of cheap aftermarket ones. If it has the Dana logo and copyright on the package, then I'd go with that it's genuine.

I have one in my truck. You might not have seen it in the thread. Works too well for me. I had to plumb in a thermostatic bypass valve so it will get up to 155°. Awesome quality. I'd recommend it to anyone but it's honestly a bit oversized for my application. Post 56....

I recall you mentioning this. And the thermostatic valve is an excellent idea and needed for certain applications where transmission heat generation can vary greatly depending how the vehicle is being used. Your truck is an excellent example - the trans can be working overtime and generating alot of heat when towing 10000-15000, but generates very little when cruising with load of groceries. In my application, that's not the case though. And I'm definitely not driving in sub 40 degree temps haha - I'd guess in that application I would need the thermostat as well.

Thanks for pointing that out Jared.
