D-MAX & BT50 2021 ONWARDS TRANSMISSION COOLER KIT (TCB646DPK) Fits ISUZU. Fast shipping, warranty included.
Category: Complete exhaust systems


The MPI Automotive TCB646DPK is a transmission cooler kit listed to fit the Isuzu D-Max and the Mazda BT-50 from 2021 onwards. It's an auxiliary cooling kit rather than an exhaust part, so the detail here stays to what the supplier actually publishes.
This is a transmission cooler kit — hardware that adds extra cooling capacity to the automatic transmission rather than changing the exhaust or the engine note. On a 4x4 ute used for towing, long hauls or sand work, transmission fluid temperature is one of the things that climbs hardest, and an auxiliary cooler is the usual way owners try to keep it in check. It is supplied as a kit by MPI Automotive; we don't have published diameters, materials or flow figures to quote, so we won't invent them.
The TCB646DPK is listed to fit the 2021-onwards Isuzu D-Max and the closely related Mazda BT-50, which share a platform from that generation. Fitment data can be imperfect, so treat this as 'listed to fit' rather than a guarantee — send us your build year and variant and we'll confirm the exact match before anything is ordered.
No — and it's worth being clear about that. This is not a muffler, cat-back or DPF part, so there's no diameter, material or sound change to talk about. It's a bolt-in cooling kit. If you came here looking for an exhaust upgrade for the D-Max, this isn't it, but it's a sensible companion for a tow rig.
