Audi Transmission Filter - Mahle HX85D

Product Information

The transmission oil filter prevents harmful particulate matter from entering the transmission valve body and damaging valve body bores, solenoids, and other fluid passages. Foreign particles in valve body bores, solenoids, or passages will cause shifting issues. Some of these issues include delayed shifts, harsh shifts, or no gear engagement in extreme cases.

Clogged filters can reduce fluid volume and flow in the transmission causing starvation of the transmission pump. This can be identified by an RPM-dependent whine from the transmission bell housing area. The transmission oil filter should be changed during any fluid service, and it is critical to replace the filter if major transmission components are replaced such as the torque converter, transmission pump, or transmission valve body.

• Whining noise from the transmission pump
• Driveability and shift quality issues including harsh shifts, delayed shifts, or no gear engagement

About Mahle

Mahle began in 1920 when pistons made of heavy gray cast iron were being used in internal combustion engines for automobiles and there was a need for a new design. The Mahle brothers countered this trend by producing light-alloy pistons at their small, newly established company however the technology was still finicky and problems come up frequently. They soon determined that they needed to come up with a solution to keep dirt and dust out of the engine so they eventually developed air and oil filters as well. Their perseverance paid off and the light-alloy pistons began to take over the market. Today, half of all automobiles produced worldwide contain MAHLE components. MAHLE offers an extensive range of parts for everyone including pistons, cylinder liners, piston ring sets, bearings, assemblies, valves, valve train components, and air, oil, fuel, and cabin air filters. Their catalog and online database of aftermarket engine components is an indispensable reference.

MAHLE Aftermarket is the world’s leading manufacturer of more than 100,000 OE and aftermarket parts, including MAHLE gaskets, engine bearings, turbochargers, thermostats, pistons and piston rings, valves, engine air and fluid filters, heavy-duty engine components, and rotating electric components such as starters, electric motors, and alternators.
