## Description

International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.

Review: Great upgrade - Good quality. Keeps the trans cool while towing up hills. I receive a damaged one at first but it was replaced with no questions or difficulties. Good customer service. Also looks great compared to the OEM cooler.
Review: Dropped trans temp. - Easy to install. All necessary parts are in the kit. Instructions easy to follow. Price was right. Dropped trans temp from 210 degree to 145 with an 8ft in bed camper on the truck. Would say that is a pretty good drop in temp.

## Questions & Answers

**Q: i want to use this on a 2007 pontiac grand prix GXP 5.3 v8 with the 4t65e-hd transmission. line fittings come with unit?**
A: It comes with generic fittings and hose clamps. I have an '05 Silverado with 5.3 and used hose clamps to factory auxiliary cooler lines.

**Q: Has anyone used this model on a 2018 Tahoe ? Will it fit?**
A: This is a universal kit, but I mounted it on my 2011 Silverado

**Q: does this fit 2017 altima??**
A: I believe if you check the dimensions it probably won't fit. Otherwise it would work. You will have to check demensions with a tape measure.

**Q: Is there any reason you can't mount this upside down (with fittings toward the ground)?**
A: I mounted it fittings down without a thermal bypass(the thermal bypass never seemed to open) and it has work great tranny temp stays around 140-180 depending on outside temp.  If you are using the thermal bypass I would say it needs to be mounted with fittings up otherwise your fluid level in the transmission will be higher than recommended due to fluid draining back into the transmission until the thermal bypass opens and allows fluid to flow through the cooler.

### ⭐⭐⭐⭐⭐ Dropped trans temp.

### ⭐ NO BYPASS - Remco does not stock 4739 - Remco will ship you 47391
*by A***N on April 9, 2022*

When I made my purchase it was fulfilled by Remco Transmission out of Texas. The description read: "Tru-Cool Max LPD4739 4739 40,000 GVW Low Pressure Drop Transmission Oil Cooler with Thermal Bypass." Tru-Cool uses two part number for the same cooler. Part number 4739 is with a thermal bypass and is more expensive. Part number 47391 is WITHOUT the bypass which is cheaper. When I received the cooler there was no part number on the box. There was no thermal bypass in the box when I opened it. When I contacted Remco through Amazon, Remco told me that the picture does not show a bypass and they do not stock the cooler with a bypass (despite the description). Remco offered me $25 off or the option to return the cooler. The bypass is about $60 available separately, so I returned it. If need a cooler with a bypass order elsewhere. If you want a cooler without a bypass order elsewhere, because you can find it cheaper than Remco. Remco is selling you the more expensive description but shipping the cheaper part. At best Remco is incompetent, at worst this is out right fraud.
