A727 [71-UP] Automatic Transmission Ring Kit

When an A727 automatic transmission starts losing line pressure or develops soft, inconsistent shifts, worn or cracked sealing rings are a common place to start. This listing covers the sealing ring set for the A727, also known as the TF-8, covering units from 1970 forward, and nothing else is included beyond that specific component.

Sealing rings sit inside the transmission and keep hydraulic pressure where it belongs. When they wear, crack, or lose their shape, fluid bypasses them and pressure drops in the circuits that control clutch apply and shift timing. Replacing them is a targeted repair that addresses the internal leakage directly rather than rebuilding around it.

This is not a full rebuild kit. There are no clutch discs, no steels, no Automatic Transmission Filter, no gaskets, no bands, and no other components in this package. If your job requires those parts, they need to be sourced separately. Buying this listing without confirming what the transmission actually needs could mean a second order before the job is finished.

Before placing the order, confirm two things: that the unit on the bench carries the A727 or TF-8 designation, and that its production year falls within the 1970-and-up coverage range. Transmission codes are typically stamped on the case or found on the build documentation. If you are unsure which unit you have, verify before ordering.

Every order is packed at the REMCO facility, where the contents are checked against the part listing before the box is closed. That listing ships inside the box so you can confirm what arrived matches what was ordered. REMCO has worked in automatic transmission parts since 1991.

• Sealing rings sized and selected for the A727 unit give the transmission the internal sealing it needs to hold pressure and function correctly.
• This listing covers sealing rings only. It does not include clutch discs, steels, Automatic Transmission Filter, gaskets, bands, or any other rebuild components. Verify what your job still needs before ordering.
• Sealing rings are among the first parts checked when an A727 loses pressure or shifts erratically. Addressing them directly targets the root cause rather than guessing.
• Content: sealing ring set for A727 TF-8 units, packed and verified against the part listing included in the box. Shipping weight: 1 lb.
• Before ordering, confirm the transmission code on the unit is A727 or TF-8 and that the application year falls within the 1970-and-up range this part covers.
