[69-UP] Automatic Transmission Ring Kit Short (Pump Rings Only 5-Metal) 86

Getting the pump circuit sealed right is what separates a rebuild that holds pressure from one that slips off the line or loses line pressure under load. This set addresses exactly that: five metal sealing rings sized and built for the pump circuit of TH250 and TH350 automatic transmission units produced from 1969 through 1986.

Metal rings for this application are not a style choice. The pump circuit in these units runs under continuous pressure cycling, and metal holds its cross-section and surface contact where softer materials can distort or take a set over time. Five rings is the complete count for this circuit on these transmissions, so there is nothing to sort or count down from a larger assortment.

This is a focused, single-purpose set. It does not include clutch friction discs, steel plates, an Automatic Transmission Filter, a gasket set, or any other sealing rings from other circuits in the unit. If your rebuild requires those components, they are separate items. Ordering the wrong set is a common source of delays on the bench, and being clear about what this listing covers and what it does not is the most useful thing that can be said here.

Each set is assembled and verified against its parts list before shipping. The listed count is what arrives. Compatible units are TH250 and TH350. Confirm the transmission code and production year of your unit before placing the order.

• Sealing the pump circuit correctly keeps fluid pressure stable and helps avoid slipping, delayed engagement, and premature wear on internal components.
• This listing covers pump sealing rings only. It does not include clutch discs, steels, gaskets, Automatic Transmission Filter, or any other seals. Review your parts list before ordering to confirm this is the specific set you need.
• Five metal rings designed for the pump circuit of TH250 and TH350 units: metal construction holds dimensional stability under heat and cycling pressure in a way soft materials cannot.
• Contents: 5 metal sealing rings, pump circuit application. Weight: 1 lb. Each piece is verified against the parts list before the box is closed.
• Before ordering, confirm your transmission code is TH250 or TH350 and that your unit falls within the 1969 to 1986 production range. Unit code is the surest way to match this set.
