25-39476 Starter Motor for Carrier Transicold X2 X4 Ultra XTC – Aftermarket

25-39476 starter motor is the direct replacement for Carrier Transicold reefer units running Tier 4 engines — and it is one of the most called-for parts we ship from Winnipeg to refrigerated fleets across Canada. If your reefer unit is cranking slow, not starting in cold weather, or has stopped firing altogether, the 25-39476 starter motor is almost always the part that needs to come out.

We stock this at ATS Auto Parts because Canadian transport operators cannot wait a week on a starter. Perishable loads do not wait. This is a new aftermarket unit built to OEM specs, priced at $275 CAD, and ready to ship.

What Is the 25-39476 Starter Motor?

The 25-39476 is a spin-on starter motor designed specifically for Carrier Transicold Tier 4 diesel engines used in trailer refrigeration units. It replaces three major OEM parts — the Mitsubishi M8T71871, the Kubota 1G484-63012, and the Delco 93607 — which are the original starters found across different Carrier unit configurations.

This aftermarket version matches the original in every spec that matters — cranking torque, voltage rating, mounting pattern, and terminal placement. Fleet mechanics fit it directly with no modifications.

Compatible Carrier Transicold Units

The 25-39476 starter motor fits the following Carrier Transicold reefer units:

X2 Series — X2 1800, X2 2100, X2 2500

X4 Series — X4 7300, X4 7500

Other Units — Ultra, Ultra XTC, Extra XT, Vector, Genesis

These are among the most common reefer units running Canadian highways and distribution routes right now. If you are maintaining a Carrier-equipped trailer fleet, there is a very high chance this starter covers your units.

Cross Reference Part Numbers

The 25-39476 starter motor is sold under several different part numbers depending on the supplier or catalog you are using. All of these are the same part:

25-39476-00, 25-39476-00SV, 25-39476-00SL, 25-39420-00, 25-39420-00SV, 25-38781-00, 25-38781-00SV

If you searched any of those and landed here, you are in the right place.

Why Aftermarket Makes Sense on Reefer Starters

Reefer units run hard — independent of the truck engine, cycling through temperature changes constantly, cold starting on prairie mornings at minus 25 or colder. The starter gets more use than most people think.

A quality aftermarket starter built to the same specs as the OEM is a practical and cost-effective decision for any fleet. The 25-39476 aftermarket unit delivers the same electrical output and cranking performance as the original Mitsubishi or Kubota starters. Fleet mechanics across Canada have installed it without fitment issues and run it through full service cycles without problems.

At $275 CAD compared to OEM dealer pricing, it is a straightforward call for any operator running multiple Carrier units.
