On transmission cooling

With the ‘new normal’ impeding many overseas holiday plans, Aussies have responded by spending a sizeable chunk of money on off-road vehicles, caravans and camper trailers and discovering our own enormous and beautiful backyard.
“Transmission coolers are a growing requirement with today’s demands,” High Performance Diesel (HPD) Operations Manager, Jason Griffith, said.
”People are gearing up with increasingly larger caravans and larger camper trailers to tour and see this great country, unwittingly putting increased strain on their standard transmissions.”
OE manufacturers do a reasonable job keeping gearboxes cool under normal driving conditions, however, HPD says it knows when you are straining your transmission trudging through remote tracks, rock steps, towing your fully-loaded home-away-from-home or fiberglass floating fortress on or off the tarmac, things can get very hot under the collar – and in the transmission case.
Increased loads can have an impact on the engine’s cooling system and disastrous consequences if fluids mix when transmission or engine cooling systems fail.
HPD says that is why, as passionate 4×4 enthusiasts, it has been inspired to manufacture air cooled transmission cooling (Transcooler) kits that provide stable transmission temperatures under the toughest conditions.

It says HPD Transcooler Kits are superior for 4×4 applications for the following reasons:
• Hard core: its solid foundation is the Bar and Plate core. For tackling hours of rough tracks and corrugated roads, HPD says Tube and Fin cores simply don’t compare when it comes to handling violent movement, constant vibration or impact from road debris. Its durability is a result of its construction from solid sections of aluminium bar, sandwiching rows of fin and braised in a furnace to form a highly robust, solidly bonded unit. Bar and Plate cores also have the advantage of easily being made significantly thicker than tube and fin cores. Thicker cores mean increased surface area and more fin for extra cooling performance.
• Precision machining: HPD says its kits’ tanks and fittings are a thing of beauty and are a testament to its relentless attention to detail, all precision-manufactured in-house and CNC machined from solid billet alloy. The thinnest section of the tanks is 4mm thick to withstand high fluid pressures and impact from rocks and other debris. The mounting brackets are lasercut from 3mm thick, 304 grade stainless steel to resist rust and corrosion.
• Testing: once HPD’s team of highly skilled precision welders bond the tanks to the cores, it says all Transcoolers are tested to cope with pressures beyond normal operating conditions. As a result of HPD’s research and development, it says hoses with superior heat resistance are supplied to cope with higher temperatures produced by the latest generation of automatic transmissions.
• After sales support: Not only does HPD say it uses only the best materials, manufacturing and design technologies, it states it also stands by its products with “after sales support that is second to none.”
“We don’t make parts you just throw away when they fail and buy the next one. We make parts that you can keep using for decades,” HPD Director, David Mitchell, said.
