Does the BMW DCT oil pan require sealant to install?

No. Unlike some aftermarket pans, the BMW DCT oil pan ships with an OEM-specification gasket for a clean, direct-fit installation without sealant.

Can I keep my factory DCT filter with this BMW DCT oil pan?

Yes. The BMW DCT oil pan retains full compatibility with the OEM DCT filter system and reuses the factory magnet. MMX recommends refreshing the suction and pressure filters during installation as a best-practice service item.

What are the three -8AN ports on the BMW DCT oil pan for?

The three additional -8AN ports support external oil cooling circuits or temperature monitoring sensors, giving track builds and high-output applications the ability to add a dedicated DCT oil cooler or logging setup without fabrication.

What is the steel insert transfer and why is it required?

The OEM plastic DCT sump contains 14 steel thread inserts that the pan bolts thread into. These must be pressed out of the factory plastic pan and transferred into the MMX billet aluminum pan before installation, since the BMW DCT oil pan uses the same bolt pattern. Professional installation is recommended to ensure correct insert seating and torque sequence.

Which finish should I choose for the BMW DCT oil pan?

Black anodized (MMR40-1601) suits a stealth OEM+ underbody appearance; clear anodized (MMR40-1602) showcases the machined billet finish for those who want the upgrade visible. Both finishes offer identical corrosion resistance and performance.

Description

MMX Billet Aluminum DCT Oil Pan for BMW M Vehicles with 7-Speed DCT

BMW DCT oil pan from MMX Performance replaces the factory plastic sump with a precision-machined 6061-T6 billet aluminum unit engineered to address the three fundamental limitations of the OEM pan on a performance-driven DCT: insufficient fluid capacity, poor heat management, and oil starvation under high lateral and longitudinal loads. The BMW DCT oil pan adds up to 1.4 liters (1.48 quarts) of additional fluid capacity over the OEM plastic unit, which buffers against the thermal degradation that occurs when a hard-driven DCT repeatedly cycles the same small volume of fluid through increasingly high temperatures. Aggressive external cooling fins maximize heat dissipation surface area, and integrated internal baffling controls fluid movement to prevent oil starvation during the cornering and acceleration forces that track use and spirited road driving generate, keeping clutch operation and hydraulic pressure consistent throughout a session. Three additional -8AN ports support external oil cooling circuits or temperature monitoring sensors for track builds and high-output applications. Ships with an OEM-specification gasket; no sealant required, and retains compatibility with the factory DCT filter and magnet. Available in black anodized (MMR40-1601) or clear anodized (MMR40-1602) finish. DCT-equipped vehicles only; note that 14 steel inserts must be transferred from the OEM plastic sump prior to installation.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
