Teflon sealing rings cut to the A404, A413, and A670 units are what this kit delivers, covering the 30TH application for model years 1978 through 1981. What separates this item from a generic ring assortment is that it is put together specifically for that unit family and year range.
Internal hydraulic leaks inside an automatic transmission often trace back to worn or hardened sealing rings that can no longer maintain pressure across apply circuits. Replacing them with Teflon rings is a direct response to that failure mode, because Teflon holds its shape and sealing contact under the temperature swings a transmission sees in normal operation, where rubber tends to harden and lose its interference fit over time.
Every ring in this kit is verified against the packing list before the box closes. That list ships inside the box, so when you open it you can check each piece against what should be there. REMCO has been working in automatic transmission parts since 1991, and the kits leave here assembled by hand, not pre-packed by a machine.
This kit does not include friction discs, steel plates, gaskets, or Automatic Transmission Filter. Its scope is the sealing rings for the 30TH application of the A404, A413, and A670. If your job calls for a broader overhaul, confirm separately that you have the other components covered before this part ships.
Before placing the order, verify the transmission code on the unit, confirm the year is within 1978 to 1981, and confirm the 30TH designation applies. The unit weighs 1 lb shipped. Getting those details right before checkout is the only way to make sure these rings fit the bore dimensions and groove specs your unit requires.
- This sealing ring kit addresses internal hydraulic leakage in the A404, A413, and A670 units, helping restore proper line pressure and clutch apply feel across the 78-81 application range.
- This kit does not include friction discs, steel plates, Automatic Transmission Filter, or band. If your repair requires those components, review your parts list carefully before ordering to avoid a second order.
- Teflon sealing rings hold a consistent seal under heat cycles that rubber cannot maintain as reliably inside an automatic transmission, making material choice relevant to how long the repair holds.
- Kit weighs 1 lb. Contents are Teflon sealing rings for the 30TH application within the A404, A413, and A670 family. A packing list is included in the box so you can verify every piece on arrival.
- Before ordering, confirm the exact transmission code stamped on your unit, the model year falls within 78-81, and that this is the 30TH variant. Ordering for the wrong variant will result in parts that do not fit.
