Sealing Washer - sump plug sealing washer for the ZF four-speed automatic gearbox.

Fitted under the head of the transmission sump drain plug, the washer compresses on tightening to form a fluid-tight seal and stop automatic transmission fluid weeping past the plug threads. Renew each time the plug is removed for a fluid change, as the washer deforms in service and will not reseal reliably once used.

Frequently asked questions

What is the STC1060 sealing washer for?

The STC1060 sealing washer seals the sump drain plug on the ZF four-speed automatic gearbox. It sits under the plug head and compresses on tightening to form a fluid-tight seal, stopping automatic transmission fluid weeping past the plug threads after a fluid change.

Can the STC1060 washer be reused?

No, this washer is best treated as single-use. It deforms as it compresses against the ZF gearbox sump plug and won't reseal reliably once disturbed, so fit a fresh STC1060 every time the plug is removed for an ATF change to avoid a slow transmission fluid leak.

Is RTC4646 the same as this washer?

Yes, RTC4646 is a cross-reference for the STC1060 sealing washer, so a listing under either number refers to the same ZF four-speed gearbox sump plug washer. Either code fits the same drain plug application.
