Transmission Funnel Adapter

The LOKAR Transmission Funnel Adapter (ATA-6900) is an essential accessory for anyone performing transmission fluid service, maintenance, or diagnostics on custom or stock vehicles. Whether you're a weekend mechanic, restoration enthusiast, or professional technician, this adapter eliminates messy spills and simplifies the process of accessing your transmission dipstick tube. Unlike pouring fluid directly into the opening—a practice that invites waste and contamination—this purpose-built funnel adapter guides fluid precisely where it needs to go, protecting your engine bay and transmission components from costly damage.

Engineered from durable aluminum with a clear vinyl inlet tube, the Transmission Funnel Adapter combines lightweight construction with visibility, allowing you to monitor fluid level and flow in real time. The aluminum body resists corrosion and heat degradation while the flexible vinyl tubing conforms to tight engine compartments and awkward dipstick angles—a critical advantage in modern vehicles where space is at a premium. The clear design lets you observe fluid color and condition as you pour, making it easy to spot contamination or old fluid requiring deeper service. At just 0.08 lbs and compact dimensions (5.8 x 0.8 x 7.6 inches), it stores easily in any tool kit without adding weight or bulk.

This adapter works seamlessly with LOKAR transmission dipsticks and is ideal for both DIY transmission top-offs and professional service bays where precision and cleanliness are non-negotiable. Automotive restorers, hot rod builders, and transmission specialists rely on this adapter to maintain clean work environments and prevent accidental overfilling or cross-contamination. It's especially valuable when working on vehicles with low-clearance engine bays, custom engine builds, or tight underhood packaging where standard funnels simply won't fit. Pair it with your existing dipstick for faster, safer, and more professional-grade transmission maintenance every time.
