'Chevrolet Silverado 1500 4.8 L with L 4l60e 4 speed transmission'. I purchased this because of the good reviews and price. Yes! I expected the tubing to be too short, yet I did not expect that it is not the correct specifications. So, incl tax, for $26 I bought 8 ft of the correct tubing SAE J 1532. Too from Home Depot got, 4 of 1/4 X 1 inch bolt / nut / lock washer, incl tax, for $2.08. So total additional expense for hardware is $28.08. Later needed just two bolt/nut/washer sets. In my case, reliable report indicates the extra Transmission Oil needed is 1 pint, that includes the hookup tubes, i.e. 1/3 of that just for those the rest is what the cooler capacity, 2/3 rd of a pint. (See below, due to heat expansion of the new parts, in the end I needed 1 and 1/2 pints of fluid to bring a hot 180 F + level to near full level on the hot register of the dipstick.) Installing: Not right away, as the summer season is near over. But I do want to share, and insist against all the misinformation out there, the unit can be installed in any orientation maximizing air flow. So there is no top or bottom, back or front to this. All manufacturers assert the connection can be either top, side or bottom, because the hot fluid is forced down the main feeder through the smaller orifice of the cooling rails, ditto for the out feeder sucking from those because it too has a larger diameter. Will re-edit and report again when the unit is installed. June 22 2023. Today I installed the unit. Couple of gotchas - Mechanic instructed me NOT to put any Fluid in the cooler, or lines, at all when installing. Later check the levels, and IF needed add some! Makes sense because there is altogether 5 Quarts in the system, a pint is just 10% of the capacity. Second on my Truck, following U Tube direction for a similar truck, make sure to locate the cooler tabs on its bottom behind the bottom rail of the truck body framing; so that there is room to replace the bracketing for the grille! You only need 6 bolts and washer sets to do this install. 4 on the top, and two on the bottom. Drilling is required because some of the holes in the brackets do not line up, and cutting to accommodate the hookups if installed to the lower setup, see photo. Passed leak inspection. After the road test; Outdoors today in S Texas at 3.PM in my yard 102 F, slight cooler breeze. Cross town just now, an incline in light traffic, transmission got to 150F, on the way back, down incline 133F. Before the upgrade, those figures would have been 178F, 147F. Topping up the fluid to its prior state; after warming the trans up, had to park and let run a couple of minutes to get to the test range of 180 - 200 F . I needed just under a pint of fluid to get close to where it was before the upgrade, which later turns out to be a wee bit low. But seeing as that is nearly what the capacity of the cooler + lines is NOT a reason to add fluid before doing the correct level check! My mechanic says that sometimes it will not be the same, so wait until after install to check the levels. 2nd Update, June 27th, 2023. Rechecked trans fluid levels yesterday, 26th, and found it just over the low mark on my dip stick. It has a hole drilled at both the high and low, making easy reading. I added just 1/16 of a pint of fluid to bring the level to just a hair above the high level hole on the dipstick; IOW @ 190 F, about right. Today on road test on the Interstate, drives great! At the limit, 65 mph, S Texas temp 89 F, the transmission temp 133 - 140s. Coming home again in traffic it went up to 151 F, then back down to 149 F. Overall, very satisfied with the product, and pleasantly surprised with a far smoother shifting of gears; icing on the cake! 3rd update, July 6th, 2023. Just to be sure I again checked and found my levels back at just over the bottom hole in the dipstick, so according to my manual that indicates I could put 0.5 L / 1 pint, in to bring the level up to the top hole of the hot range. Instead I chose to put 1/2 pint in. Road tested twice and measured each time I came to the average of well over the lower hole in the dipstick hot range, but a wee bit lower than the top hole. I can only account for the extra fluid needed being due to expansion of both the cooler and the hoses. So of the 1 quart I started with I have just under 1/2 pint left. Again changing gear is buttery smooth! And cross town in traffic never goes over 151F. Very pleased!

Easy assembly looks and runs great. Great value keeps transmission cool on my 2010 Chevy Silverado

This kit deserves zero stars for including absolute garbage hose. After only four months of use the hose split and dumped several quarts of fluid, nearly costing me a $3,000 transmission rebuild. Not only was there a break (pictured) but while removing the internal webbing was all red, indicating whatever sub par gunk the hose is made from was breaking down completely. If you're here, you dont want to pay for the name brand cooler. The heat exchanger itself does work well but do yourself a favor and throw away the hose immediately, purchase a length of correct SAE J1532 rated transmission cooler line. This could have been much worse had I been towing or far from home all due to a cheap 3/8 hose.
