BMW Drivetrain Parts for BMW Z Series G29 (2019+)

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.

Eliminate the factory clutch delay valve and enjoy faster, more precise clutch engagement with the ECS Clutch Delay Valve (CDV) Removal Tool Kit. Designed for F and G-Chassis manual BMWs, this kit makes removing the hydraulic restrictor safe, simple, and reliable, no slave cylinder removal required.

Most modern BMWs come from the factory with a plastic slave cylinder featuring a CDV, intended to smooth engagement and reduce driveline shock for less experienced drivers. In practice, this restrictor can dull pedal feedback, slow shifts, and increase clutch wear. Removing it restores the sharp, direct clutch feel that BMW enthusiasts expect.

Key Benefits:

Faster, more predictable clutch engagement
Sharper pedal response and connected driving feel
No need to remove the slave cylinder
Tool Design:

Machined from durable 304 stainless steel
Includes precision removal and insertion tools
Knurled grip for easy handling
Built-in depth and angle control protects internal surfaces and ensures proper grommet alignment
Removal and Installation:

Disconnect the Clutch Line
Remove the clutch line from the slave cylinder to access the factory clutch delay valve.
Remove the Restrictor Plate
Thread the removal tool into the center of the small grommet. Once engaged, carefully pull the tool to remove the grommet and restrictor plate. The small rubber sealing O-ring will come out along with the plate.
Reinstall the O-Ring
Place the rubber O-ring onto the installation tool. Insert the tool into the slave cylinder to properly seat the O-ring in its original position.
Reconnect and Bleed the Clutch
Reattach the clutch line, add fluid, and bleed the system according to your manufacturer’s instructions.
Enjoy Enhanced Clutch Feel
With the delay valve removed, your clutch now engages faster and more predictably, giving your manual transmission the sharp, connected feel it was designed for.
