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 Review: 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. ## Features - 40k Transmission Oil Cooler lpd47391 Compatible with tru cool Heavy Duty 40,000 GVW Max - low pressure drop trans cooler ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D99MDZ1X | | Assembly Required | No | | Brand | Lucky Seven | | Customer Reviews | 4.0 4.0 out of 5 stars (108) | | Date First Available | 1 August 2024 | | Exterior | Brushed | | Generic Name | 40k Transmission Oil Cooler | | Item Dimensions LxWxH | 10.2 x 7.6 x 7.6 Centimeters | | Item Weight | 113 g | | Item model number | LPD47391 40k | | Manufacturer | 40k Transmission Oil Cooler | | Manufacturer Part Number | LPD47391 40k | | Model | 40k Transmission Oil Cooler | | Product Dimensions | 10.16 x 7.62 x 7.62 cm; 113.4 g | ## Images ![40k Transmission Oil Cooler lpd47391 - Image 1](https://m.media-amazon.com/images/I/81S0F4hZs5L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***N on 11 January 2026* Had this trans cooler on my truck for at least 6 months now and it has not given my a sing issue.

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. ## Frequently Bought Together - 40k Transmission Oil Cooler LPD47391, Heavy Duty 40,000 GVW Max, Low Pressure Drop, Compatible with Tru-Cool,Includes Mounting Hardware-Ideal for Heavy Vehicles,40,000 GVW transmission cooler (Silver) - EVIL ENERGY 6AN Male to 5/8 x 18 Inverted Flare Thread Fitting Adapter Straight 2Pcs - EVIL ENERGY 6AN Fuel Line Kit, 6AN Nylon Braided Fuel Line Hose Fitting Kit CPE 20FT Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/785655047-40k-transmission-oil-cooler-lpd47391](https://www.desertcart.co.th/products/785655047-40k-transmission-oil-cooler-lpd47391) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-28*
