Description:
PP-23502664 Detroit Diesel Transmission Cooler
This Seakamp Transmission Cooler is a marine-grade replacement designed for Detroit Diesel two-stroke and four-stroke marine diesel engines, most commonly fitted to the MTU family. The unit has a 3" Diameter core.
The transmission cooler circulates gearbox oil through a tube-and-shell core where raw water absorbs heat, keeping marine gear oil within its specified operating range. Stable gear-oil temperature is critical for clutch-pack longevity, bearing protection and consistent shift engagement under continuous load.
Marine gear oil that overheats loses its load-carrying additives, leading to clutch slippage, premature bearing wear and seal failure. A correctly functioning transmission cooler preserves shift quality, protects the gearbox internals, and is especially important on high-torque diesel installations and prolonged trolling duty.
Manufactured to match OEM dimensions, port orientation and mounting geometry, the 23502664 is a true direct-fit replacement for the original Detroit Diesel component. It installs without modification to existing hoses, brackets or pipework, making it suitable for planned maintenance, corrosion replacement or preventative servicing.
