This article discusses how to diagnose and fix one of the most popular Audi Quattro transmission leaks associated with the 5 Speed ZF automatic transmissions. Learn the symptoms of this common leak which often comes from the tailshaft flange seal area. This transmission leak information also applies to VW Passat 4Motion models with the ZF 5 Speed transmission.
Audi Transmission Tailshaft Flange Seal Leak
This information is also applicable for select VW Passat 4Motion models.
In Blauparts service repair shop we've repaired many different types of Audi transmission leaks. The most common being the Audi Quattro tailshaft flange seal leak. This leak is often due to the high temperatures created by the catalytic converters, which are located directly bellow the Audi tailshaft flange seal area. Extreme cold-to-hot temperature fluctuations attribute to the Audi tailshaft flange seal becoming hard and brittle. Overtime, typically around 70,000 miles, the tailshaft seal commonly begins to leak fluid due to its inability to properly seal. Unchecked, the Torsen differential which is directly responsible for the Quattro system can eventually be depleted of critical gear lubrication. An unfixed tailshaft flange leak can impact the reliability and longevity of the Quattro system and lead to very costly transmission problems or failure in the future.
