BMW Transmission Parts

The ZF 8-speed automatic transmission (8HP) has become the go-to choice for performance enthusiasts, delivering lightning-fast shifts, impressive torque handling, and ample tuning potential. However, the stock transmission pan falls short in critical areas. Its plastic construction, integrated non-replaceable filter, and limited fluid volume leave little margin for error in demanding conditions.

To address these limitations, we've engineered a premium solution: a cast aluminum transmission pan that boosts durability, cooling performance, and serviceability. Designed with enthusiasts in mind, this upgraded pan increases fluid capacity by 1 liter to reduce transmission temperatures and improve long-term reliability, even under aggressive driving or track conditions.

Built to outlast and outperform the OEM plastic pan, the aluminum construction resists damage from road debris and eliminates the risk of cracking. Our pan is hard-coat anodized in black for superior corrosion protection and a long-lasting finish that looks as good as it performs.

Our aluminum pan upgrade is engineered to work seamlessly with the OEM G8X 8HP transmission filter (24007855263), allowing for easy and cost-effective fluid service. Integrated magnets help to trap metal particulate, extending the life of your transmission by keeping contaminants out of the fluid.

Key Features:

Cast aluminum construction offers superior strength and resilience over the OE plastic pan

Increased fluid capacity (+1L) enhances thermal management and reduces the risk of overheating

Serviceable design uses the OEM G8X transmission filter for easy, affordable maintenance

Hard coat anodized finish provides exceptional corrosion resistance and longevity

Integrated magnets collect metallic debris, protecting transmission internals

Installation:

Vehicle plastic belly pans may vary. Because the Turner 8HP transmission pan is taller to allow for increased fluid capacity, some vehicles may require trimming of the plastic belly pan, or the belly pan may need to be installed over the transmission pan where it may make contact.

The ZF S5D 320Z 5-speed transmission is known for its robust design, exceptional durability, and impressive power-handling capability. Unfortunately, as these transmissions age, shifter-related issues have become increasingly common. Problems such as difficulty selecting gears, a sticky shifter, or a decline in shift quality are often the result of worn detent springs, pins, and bushings. These components are essential for precise gear engagement and proper shifter centering, making their replacement a critical step in maintaining optimal performance.

Replacing detents requires specialized tools known as "drifts," which are notoriously hard to find. Fortunately, we've developed a complete Detent Tool Kit, featuring five precision-engineered drifts designed for exact fitment in the ZF transmission's detent bores. This toolset makes detent replacement straightforward and minimizes the risk of damage to internal transmission components.

Features

Complete Tool Kit: Includes five precision-machined drifts specifically designed for the ZF 5-speed transmission’s detent bores and caps. Hassle-Free Detent Replacement: Simplifies the process of removing and installing detents with professional-grade precision. Protects Your Investment: Reduces the risk of damaging internal transmission components during service. Durable Construction: Made from heavy-duty 1045 steel for exceptional strength and long-lasting reliability.

Used when retrofitting an OEM or aftermarket CSL intake on a vehicle with SMG transmission.

Its no secret the CSL intake plenum is the pivotal upgrade for your S54. If you are fortunate enough to have an SMG equipped vehicle you are going to need a bracket to relocate the expansion tank. Our Turner motorsport bracket fits perfectly with the engine bay to facilitate the installation of your genuine or Turner branded CSL intake plenum.

URO AT Plug Sealing Sleeve - BMW E8X E9X

URO AT Plug Sealing Sleeve - BMW E8X E9X is designed to replace a cracked or hardened original automatic transmission valve body sealing sleeve. This component is essential for preventing automatic transmission fluid (ATF) leakage, which can degrade transmission performance. Manufactured with an OE-style o-ring profile and high-quality materials, the sealing sleeve ensures a proper compression seal between the sleeve and valve body, effectively maintaining your vehicle's transmission integrity. Designed to withstand intense transmission heat and resist ATF degradation, it guarantees long-lasting reliability and optimal performance.

Key Benefits:

• Prevents ATF leakage by replacing cracked or worn valve body sealing sleeves, maintaining transmission function
• OE-style o-ring profile ensures proper compression and seal between the sleeve and valve body for leak-free operation
• High-quality materials resist heat and corrosive ATF degradation, extending the lifespan of your transmission components
• Easy to install with a direct-fit design, ensuring proper installation and performance
• Restores optimal transmission performance, helping to avoid costly repairs due to fluid leakage or heat damage
