Fitment Note: Fits ZF A5S325Z - ZF5HP19 Trans Type Only. The 2001 525i E39 platform came with three 5 speed transmission possibilities. These models could have the 5 speed ZF A5S325Z, 5 speed GM A5S360R, or 5 speed GM A5S390R automatic transmission. This kit fits the 5 speed ZF A5S325Z automatic transmission. It is the responsibility of 2001 BMW 525i E39 platform owners to determine their transmission type before ordering and clearly designate '5 speed ZF transmission'. 2002-2003 BMW 525i E39 platform owners should not have to determine a transmission type as these should all be a ZF 5 speed.

Why change your BMW E39 525i transmission fluid and transmission filter?
Your BMW transmission has hundreds of moving components. Over time these internal components mesh with one another, begin to wear, and create fine metallic particles. These fine metallic particles contaminate your BMW transmission fluid and plug the transmission filter. This contamination affects your transmission's efficiency and long-term performance, causing more friction and wear on transmission components. By having a regular transmission fluid and filter service interval for your BMW, you will easily extend the life of your transmission. With clean ATF and a fresh transmission filter, you will be providing clean lubrication and proper filtration for your transmission. This important maintenance interval will support a long-lasting well lubricated, and protected transmission, minimizing the chances of costly transmission repairs and problems.
When should your BMW E39 525i ATF transmission fluid be changed?
We have observed the BMW 5-Speed transmission fluid getting contaminated earlier than usual. The ATF has a dirty metallic tint as soon as 60,000 miles. We recommend changing BMW transmission fluid and transmission filter every 50,000 to minimize the chances of wear on critical transmission components. Many people choose to just flush the transmission fluid. At Blauparts, we recommend the transmission fluid and filters be changed along with the related components. This can greatly maximize gearbox performance and service life.
Having regular BMW transmission fluid and filter services on your BMW is great preventive maintenance. Having a regular service interval for your transmission is much more logical and inexpensive in the long term. Neglecting your BMW transmission can lead to costly transmission repairs or even having to replace a transmission for several thousands of dollars.
