Lisle 17892 Transmission Drain Pan - Large Flexible Catch Funnel

In this review of the Lisle 17892 Transmission Drain Pan the bottom line is simple: this is a practical, no-nonsense funnel for anyone who performs transmission fluid service and needs a large, resilient catch area. The reviewer found it especially useful for full transmission fluid changes where stray splashes and loose parts are a concern. Made of heavy-duty flexible plastic, the pan expands the effective catch area of any lift drain and reliably returns to shape if stepped on, making it a useful shop tool rather than a one-off disposable funnel.

Key Features

• Heavy-duty construction: Thick plastic provides chemical resistance and a sturdy surface that stands up to shop use and contact with transmission fluid.
• Extended catch area: The wide 22' x 23' dimensions increase the effective drainage footprint and reduce spills around the lift drain.
• Flexible design: If crushed or driven over it will return to its original shape so it continues to function after rough handling.
• Loose parts catcher: The funnel shape helps trap loose bolts or small components so they are not lost during service.
• Mess-free operation: The size and shape make it easier to direct fluid into a container, keeping floors and pits cleaner during drain operations.

Who It's For

The Lisle 17892 is aimed at DIY mechanics, independent shops, and fleet technicians who perform transmission fluid changes and want a durable, reusable funnel to extend the catch area of an existing lift drain. It is especially helpful when changing fluid from vehicles with larger pans or when complete fluid evacuation is desired.

Those who should look elsewhere include technicians needing a sealed, pump-ready containment tank or a funnel with built-in measuring marks; this product is a simple, flexible catch funnel rather than a metering or pump device.

Pros & Cons

Pros

• Durable plastic construction resists harsh chemicals and daily shop wear.
• Large 22' x 23' size reduces spills and makes full transmission changes cleaner.
• Flexible material returns to shape after being run over, extending usable life.

Cons

• Not a sealed containment tank, so it still requires a separate receptacle for used fluid.
