Lucky Seven 40k Transmission Oil Cooler lpd47391

Had this trans cooler on my truck for at least 6 months now and it has not given my a sing issue. The install was simple. I installed this on my 99 Silverado for my built 4l60e and have seen my trans temps stay low even after doing hard pulls. Amazing price and quality

The Cooler developed a leak about 8 months after i purchased it, or about 15,000 miles. The leak isn't necessarily the reason why i'm writing this review, i'm writing this review because I messaged the seller trying to claim the warranty, and I did not hear back from the seller. I purchased this specific cooler for the lifetime warranty and it seems like I won't be claiming that anytime soon. Also, this is NOT from the tru cool brand, I already knew that when I purchased it however to those of you who are confused, it's not from tru cool.

Works great! I put it in my Wife's 2018 tahoe as a replacement cooler after her transmission went out. i bypassed the AC condensor cooler that was originally installed. Runs 170 after long drive on highway.

I really liked the cooler itself. It did the trick in reducing my trans temps in my motorhome. After seeing other reviews, I decided to avoid the use of the included hose (which was too short to do much with anyway) - and built myself 3/8 lines with 5/8-18 inverted flare nuts. Those fit fine - but do take a bit of work to get them to seal (that may be an artifact of my flares and not the cooler itself). The only negative I found on the cooler is that it is a pretty soft material - be careful when tightening the inverted flare nuts into the cooler - the attachment female portion bends easily.

Well packaged. Installed into diesel with allison 1000, It dropped transmission temperature 20° - 25°. Update: replacement ordered, weld broke and failed. 2nd replacement failed. Will not order again.
