    Tests have proven that a 20° drop in transmission fluid temperature can double the life of automatic transmission components. Cooler tranny oil gives more reliable, consistent shifts under racing conditions, and prevents transmission damage under extreme towing conditions. These transmission coolers provide a reliable means of cooling your auto transmission. Cooler capacity is based on GVW rating. Select cooler size based on severity of service.

    Rated 4 out of 5 by from Inexpensive, Decent Cooling Reasonably quick and simple installation, although some modifications were necessary for a less common application. Installed on a 1997 Volkswagen Passat B4 VR6 automatic. This vehicle uses an Oil-To-Water cooler which is physically attached to the transmission case, rather than being remotely located in the radiator. This OTW cooler cannot be bypassed or connected in series; it must be removed entirely in order to install an aftermarket cooler. Use of two 12mm x 1.5 metric thread to -6an adapters, plus two new 13mm x 2.5mm o-rings is required. Prior to installation of this cooler, in an ambient temperature of ~90F (~32C) trans temperatures peaked at 280F-290F (137C-143C), with an average operating temperature of 270F (132C). These exorbitantly high temperatures were due to the inherent nature of the coolant passages of the OTW cooler on this transmission (VW O1M) to clog. After installation of this cooler, in similar ambient temperatures, trans temperatures peak around 210F (99C), and average operating temperature is around 190F (88C). Still not ideal, however it's a significant improvement, and the behavior of the transmission is remarkably better. No fluid was changed or added during the installation of this cooler. All changes in the transmission's behavior are creditable directly to the use of this cooler. All that being said, I don't think the GVW rating system this and many other coolers use is of any actual use, and I am VERY glad I didn't follow the manufacturer guidelines about how to choose a cooler. This vehicle has a listed GVW of approximately 4500 lbs. This 18,000 lb. GVW rated cooler is not able to bring the transmission temperatures down to what would normally be considered "optimal" (170F/77C), even considering it's optimal mounting location (in front of the A/C condenser and radiator, with full air flow through hole in bumper, and full flow from the auxiliary fan). I've deducted one star due to this cooler's optimistic-at-best GVW rating.
