Review: Works great, trans stays under 160* - Works great so far, it is large and may not fit smaller vehicles but was easy to install on my 03 Chevy avalanche and keeps the transmission under 160* even when towing. I did bypass the radiator built in heat exchanger as I live in the south and do not need a trans heater.
Review: Great quality - Has preformed spectacular on my truck. It's a mildly build 5.3 with an extremely built 4l60E it keeps temp noticeably lower and holds pretty consistently when I abuse the truck will purchase for any project

### ⭐⭐⭐⭐⭐ Works great, trans stays under 160*

Works great so far, it is large and may not fit smaller vehicles but was easy to install on my 03 Chevy avalanche and keeps the transmission under 160* even when towing. I did bypass the radiator built in heat exchanger as I live in the south and do not need a trans heater.

Has preformed spectacular on my truck. It's a mildly build 5.3 with an extremely built 4l60E it keeps temp noticeably lower and holds pretty consistently when I abuse the truck will purchase for any project

### ⭐⭐⭐⭐⭐ Came in clutch
*by L***I on September 4, 2024*

Installed on my 2016 Silverado prior to an 850 mile trip while hauling my C10 just for piece of mind. Halfway through the trip my stock trans cooler cracked as we pulled into the hotel, leaking trans fluid everywhere. I just Re-routed the lines to bypass the stock cooler and use this as the primary. Worked great going through the mountains in 100° weather, this along with the trans TBV kept the temps around 130-140°. 5 months now and no issues whatsoever. For a fraction of the cost that the mishimoto goes for, this does the same job imo. The ONLY thing I needed was additional hose to route it how I wanted. $14 for an additional 5ft of hose at NAPA.
