Gearbox Oil Cooler Radiator 124100-6450 HD-OC-1203 Transmission Oil Cooler for Car Gearbox Cooling System 1 Piece
Gearbox Oil Cooler Radiator 124100-6450 HD-OC-1203 for Car Transmission Cooling

This gearbox oil cooler radiator is a replacement cooling component for car transmission systems, listed with part number 124100-6450 and model number HD-OC-1203. It is intended to fit car applications, and the source describes the applicable vehicle model simply as suitable for cars. The specification is given as Oil Cooler, and the product is supplied as one oil cooler. Because the listing centres on the part number and model number, it is most useful to buyers who are matching a worn or damaged gearbox oil cooler against an existing unit. No dimensions, material details, colour, or performance ratings are included in the source text, so those points cannot be confirmed here. Buyers should verify the part number and model against their vehicle before ordering, particularly where several gearbox variants exist. The product is presented as a single-component replacement rather than a full kit, and no additional fittings, hoses, brackets, or mounting hardware are stated in the source information.
Features and Construction

The source information for this gearbox oil cooler radiator is limited to its name, model, part number, vehicle suitability, specification, and packing list. It is identified as an oil radiator cooler, model HD-OC-1203, part number 124100-6450, suitable for cars, with the specification Oil Cooler and a packing list of one oil cooler. No material composition, dimensions, surface finish, or construction method are provided, so this section stays within those stated facts.
Part Number and Model
The two main identifiers for this product are the part number 124100-6450 and the model number HD-OC-1203. These are the most practical details for matching the cooler against an existing gearbox oil cooler. Because the source does not list any alternative part numbers, cross-reference numbers, or interchangeable models, buyers should rely on the stated identifiers and confirm fitment before purchase. The part number appears in the listing title as well as the product information, which makes it easier to search for the same reference.
Stated Specification
The option name in the source is Specifications, and the option value is Oil Cooler. This confirms the product is supplied in the Oil Cooler specification rather than a different variant. No other specification options, sizes, or configurations are listed. That means the buyer receives the item described as an oil cooler, identified by model HD-OC-1203 and part number 124100-6450, without additional variants to choose between. This is useful for anyone who already knows the required part number and simply needs a like-for-like replacement.
Uses and Placement
This oil cooler is intended for car use, with the applicable vehicle model described only as suitable for cars. Its role is linked to gearbox oil cooling, based on the product name and title. The source does not specify which gearbox types, engine sizes, or specific car models it fits, so compatibility must be checked against the existing part number rather than assumed from a general vehicle description.
Gearbox Cooling Role
The product is described as a gearbox oil cooler radiator, which indicates its place in the transmission oil cooling system. It is intended to help manage oil temperature within the gearbox, although no temperature range, flow rate, or cooling capacity is stated in the source text. Buyers looking for a replacement unit can use the part number 124100-6450 and model HD-OC-1203 to compare against the component currently fitted. No performance figures should be assumed beyond the general function implied by the product name.
Vehicle Suitability
Suitability is given only as suitable for cars, which is broad and should not be treated as a confirmed fitment list. The source does not name specific makes, models, years, or engine variants. Before ordering, buyers should check the existing gearbox oil cooler part number against 124100-6450 and confirm that the HD-OC-1203 model matches the required unit. If the current part number differs, the buyer should treat the listing as unverified for their vehicle and seek further confirmation.
Benefits and Buying Value
The main buying value of this listing is its part-number clarity. It gives a specific part number, model number, and stated specification, which helps buyers match a replacement gearbox oil cooler without relying on vague descriptions. The source does not include price comparisons, longevity claims, or maintenance promises, so the practical value rests on identification and replacement rather than unstated performance benefits.
Replacement Identification
For a replacement part, correct identification is often the first practical hurdle. This listing provides the part number 124100-6450 and model HD-OC-1203 together with the specification Oil Cooler. That combination gives the buyer several reference points to check against the existing unit. It does not claim to fit every car, and the source does not list a universal fitment, so the part number should remain the primary check. This makes the listing most suitable for buyers who already have a reference number to match.
Why Choose This Gearbox Oil Cooler
This gearbox oil cooler radiator is a focused replacement item rather than a broad accessory. It is supplied as one oil cooler, with no extra components listed in the packing list. The stated details are the name, model HD-OC-1203, part number 124100-6450, suitability for cars, specification Oil Cooler, and package contents of one oil cooler. Buyers who need exactly that item and can confirm the part number will find the listing straightforward. Those who cannot confirm the number should seek fitment advice first, because no further compatibility data is provided in the source text.
