Specialty Items : Water-cooled Vanagon Transmission Cooler
We are pleased to be rolling out the newly designed automatic transmission cooler - an aluminum heat sink.
As parts go obsolete and business's search for solutions, it's great when advances in technology from the past 20 years can be incorporated into the designs of replacement products. Stock transmission coolers utilized engine coolant run in proximity to automatic transmission fluid, risking harmful fluid mixing and requiring expensive coolant hoses. Currently available external transmission coolers have their own pitfalls, being bulky and utilizing external lines and fittings that are prone to leaking and all of which is prone to impact from road debris. The Heat Sink is a compact, efficient solution that provides superior cooling. Automatic transmission fluid runs through the various passages to the cooling panels with four times the surface area of the stock cooler. The part tucks up above the transmission mount where the stock cooler was mounted.
Keep in mind that these transmissions do not require significant cooling. 84 and older models did not even use a cooler on this same transmission. And this same transmission (automatic section only) is also the one that was used in 87 to 92 Jetta's, again with no cooler. The stock cooler actually runs warm coolant through it. Testing of new cooler, with fluid temp gauge attached, shows improved temperature both while run under heavy load and while vehicle is running but not in motion. With higher horsepower engines, there is more need for cooling transmission fluid so this product would be particularly recommended in those applications.
