All-Metal ATF Adapter for 725.0 9-Speed

This all-metal transmission filling adapter is built for technicians and DIY owners who service Mini Cooper, Cadillac, Chevrolet and Mercedes-Benz units. Its one-piece construction meets OEM standards and resists rust during repeated fluid changes.

Thread Sizes M14*1.5 and M12*1.75

The adapter provides M14*1.5 and M12*1.75 threads plus an ear-clip fitting that match the 725.0 9-speed transmission ports. Confirm the exact thread requirement on your vehicle before ordering because an incorrect size will not seal.

Requires Volume Controller Gun

Steady, splash-free transfer only works when the adapter is paired with a volume controller gun and hose trigger. The push-on coupler speeds connection but the filler gun is not included, so plan to supply or purchase one separately.

Questions about this item

How does the M14×1.5 thread size work when the adapter is fitted to a transmission fill port?

The M14×1.5 thread matches the fill port on compatible Mini Cooper, Cadillac, Chevrolet and Mercedes 725 or 9G-Tronic transmissions, letting the one-piece metal adapter screw in directly without extra fittings.

What does the ear-clip connection limit when the adapter is used with a fluid gun?

The ear-clip end locks onto the volume-controller gun hose, so fluid flow is controlled by that gun’s trigger; the adapter itself adds no valve or restriction.

What clearance is needed around the transmission fill port to seat this adapter?

The adapter is a single metal piece with M14×1.5 and M12×1.75 threads plus an ear-clip coupler, so enough room to thread it in and clip the hose gun is all that is required.
