Bolt-on OE oil-to-water coolers used in listed VW/Audi units often leak internally and allow antifreeze/ATF cross-contamination. They are also very difficult to flush thoroughly due to internal design restrictions. Reuse of the OE cooler after rebuild can result in debris contamination and high operating temperatures due to reduced oil flow. Installing Sonnax remote transmission cooler adapter kit 119814-01K enables elimination of the OE cooler in favor of commonly available aftermarket oil-to-air cooler kits.
Cooler not included. For assistance in selecting the right cooler for your application, contact your chosen aftermarket cooler manufacturer.
