A single failed cooler line fitting on a 4L60E automatic transmission can drain fluid quietly until the damage is already done, and this direct replacement part addresses that failure point without requiring a larger kit purchase. This is one cooler line fitting, part number 1046, listed under the C9-COOLERS line, weighing 1 lb, intended specifically for the 4L60E unit.
The 4L60E has been in continuous use across a long production run, and cooler line fittings on these units are exposed to repeated pressure cycles, vibration, and temperature swings that eventually compromise the seal at the port. When that connection starts to seep, the transmission loses the fluid flow it depends on to stay within operating temperature. Replacing the fitting is a straightforward mechanical step, but using the correct part for the specific port and configuration matters.
This listing covers exactly one fitting. There are no seals, no hoses, no clamps, and no additional hardware included. If your repair requires those components, they need to be sourced separately. Review what your job calls for before placing the order.
At REMCO, individual components like this one are pulled and packed by hand, not pre-boxed from an outside supplier. Every order is checked against its part listing before it ships, and the part number is confirmed on the packaging. REMCO has been working exclusively in automatic transmission parts since 1991, and single-piece orders receive the same attention as full rebuild kits.
Before ordering, confirm the transmission is a 4L60E and identify which cooler line port the fitting serves on your specific application. Fitment details matter on this platform given how long it was produced.
- Restoring a leaking or damaged cooler line fitting on a 4L60E unit stops fluid loss before it leads to overheating and internal damage to the transmission.
- This listing covers one cooler line fitting only. It does not include any seals, hoses, lines, clamps, or related hardware. Verify this is the exact piece you need before ordering.
- The 4L60E platform spans decades of production and cooler line fittings take stress at every fluid cycle. Replacing the fitting directly addresses the source of the leak rather than patching around it.
- One cooler line fitting, weighing 1 lb. Part number 1046, cataloged under the C9-COOLERS line for the 4L60E automatic transmission. No additional pieces are included in this order.
- Before purchasing, confirm your unit is a 4L60E and check the specific cooler line port this fitting serves. Not all 4L60E configurations use identical fittings at every port.
