When the cooling circuit in a JF011E or RE0F10A automatic transmission fails, fluid temperatures climb and the rest of the drivetrain pays the price; this direct-replacement external oil cooler addresses that failure at the source. Unlike kit listings that bundle multiple components, this is a single-piece cooler sized and ported for the JF011E and RE0F10A transmission family, so you are ordering exactly what the job calls for without paying for parts you already have on the bench.The JF011E, also catalogued under the RE0F10A designation, is a continuously variable automatic transmission found in a range of front-wheel-drive applications. The external cooler sits in the fluid circuit between the transmission and the factory cooling system, pulling heat out of the fluid before it cycles back through the valve body and clutch pack. A cooler that has cracked, corroded, or lost flow capacity compromises every other component downstream, and replacing it with a unit matched to the original specification is the straightforward corrective step.At 3 lb shipped, this is a compact but solid unit. REMCO has been sourcing and distributing automatic transmission parts since 1991, and each piece that leaves the warehouse is checked against the part record before it goes out. The part number for this cooler is OC-O1148. No gaskets, connecting lines, clamps, or hardware ship with it; if your job requires those items, source them separately before starting the repair.To confirm fitment, locate the transmission identification tag or casting code on your unit and verify it reads JF011E or RE0F10A. Do not rely solely on vehicle year or engine size, as the same platform sometimes used different transmissions across model runs. Confirming the transmission code directly is the only reliable check. Restores proper fluid temperature control in JF011E and RE0F10A automatic transmission units, addressing overheating conditions that lead to accelerated clutch and seal wear. This listing is a single cooler unit only. No gaskets, lines, fittings, or hardware are included. Verify what additional parts your installation requires before ordering. Designed specifically for the JF011E / RE0F10A transmission family, this cooler matches the original configuration of the unit without requiring modifications to fit. Single external oil cooler. Shipping weight: 3 lb. No kit contents apply; what you see listed is exactly the one piece you will receive. Before ordering, confirm the transmission code on your unit matches JF011E or RE0F10A. Cross-reference your build date and application to avoid a mismatch.
