Dana-Spicer, the OEM for the Tru-Cool Thermal Products transmission coolers, is no longer offering the Tru-Cool 40K. They were abruptly discontinued in 2025 without notice to their suppliers.

We worked directly with Capital Core Transmissions, one of the registered Dana-Spicer & Tru-Cool Thermal Products distributors, who is providing this cooler as the direct aftermarket replacement for the OEM Tru-Cool 40K. This cooler is of equivalent quality and rating as the OEM Tru-Cool 40K. Capital Core Transmissions is offering this as the replacement for Tru-Cool LPD47391.

These come directly from our supplier, Capital Core Transmissions, out of Columbus, Ohio.

We can offer quantity discounts - reach out for purchases of 2 or more.
