Rein BMW Drivetrain Parts

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

Rein OE Quality Automatic Transmission Service kits address the short-lived valve body sealing sleeves and adapter in the ZF 6HP transmissions. This kit includes the necessary direct-fitting sealing hardware to conveniently service the shrunken valve body sealing sleeves during the recommended fluid and filter change interval of 62,000 miles / 8 years at the latest. The ZF 6HP19Z series transmission is a very durable and powerful unit that can last for many miles if serviced in time to allow the valve body to maintain proper fluid pressure. The slightest drop in valve body fluid pressure in this unit leads to premature transmission bushing and or clutch wear, along with contamination and overheating of the fluid. Rein recommends the OE or Pentosin ATF-1 synthetic automatic transmission fluid for this job.

Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This filter fits A5S325Z automatic transmissions on BMW E46 323i 323ci 325i 325ci 328i 328ci 330i 330ci . E39 525i 528i 530i. E85 Z4 2.5i Z4 3.0i. This kit includes the transmission filter and gasket.

Kit Contents:

  • 1 x 24341423376 - transmission filter
  • 1 x 24101423380 - gasket for transmission filter

This item fits the following BMWs:
3/2000-2004 E46 BMW 323i 323ci 325i 325ci 330i 330ci

The carrier bearing supports the center of the drive shaft between the transmission and the differential. As miles and age increase, bearing failure can occur resulting in a howling noise. The rubber mount may degrade as well, causing excess vibration from the drive shaft. When disassembling drive shaft make sure to mark each section, as these are balanced as a unit.

Don't neglect your motor mounts! Most stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).

As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over.

Rein OE Transfer Case Overhaul Kit is a solution kit developed to perform a complete overhaul of the xDrive transfer case. The complete kit includes bearings, clutch packs, shims, magnets, retainers, hardware, seals, and other necessary internal components. Until now, the only solution to repair these failure-prone transfer cases was to replace them with a complete assembly at the dealer or install a used assembly at the local shop. No other options were available due to no offering for internal components. All the components offered in Rein's Transfer Case Overhaul Kit are OE, identical to the original parts on the vehicle direct from the factory.
