To produce this transmission cooler for the R35 GTR, we’ve teamed up with one of the world leaders when it comes to oil cooling, Mocal, and together we have produced a comprehensive kit that relies on both companies expertise and delivers excellent results
The cooler itself is a massive 25 row 235mm wide Mocal unit, fully ducted into the spare duct on the front bumper which improves the coolers efficiency. It's fed by braided -8 lines and Aeroquip hose aluminium hose ends. The pump is Mocal’s own, delivering an amazing 5 litres of transmission oil every 30 seconds to the cooler – enough to completely change the oil in the transmission every minute!
The transmission cooler is thermostatically controlled so only comes on when the transmission oil reaches 100 deg C (212 deg F), and turns off again at 95 deg C (203 deg F). This allows the transmission to reach a temperature that burns off any water based contaminants in the oil (e.g. condensation) before the cooler cuts in.
During our track testing in 22 C ambient (72 F), a 20 minute hard drive around Silverstone saw transmission temperatures of just 112 C (234 F) maximum, and during a 2.5 mile cool down lap, the cooler brought the temperatures down to the point the cooler turned off, i.e. below 95 C (203 F)
This is a COMPLETE kit – all nuts/bolts/brackets are included, together with a genuine Nissan sump gasket, and a bespoke wiring harness with all the connections pre-made. A CD is included that provides a full colour installation guide around 40 pages long. This cooler adds 2 litres of oil to the system so please take that into account when you are purchasing the oil for this installation.

Do not use aggressive (acidic) car cleaning products, particularly traffic film remover solutions or shampoos to clean your intercooler, radiator or oil cooler. The use of these products can damage Forge Motorsport cooling systems and invalidate your warranty. These are often found at car washes. A light, warm, soapy solution (free of harsh acidic cleaning compounds) should be used to clean you cooler and thoroughly rinsed away. We recommend that you should inspect your product on a regular basis for bent and/or crushed fins. Any bent fins should be carefully straightened to allow ambient air to pass through the core face. At the time of installing your Forge radiator, an approved coolant must be used and added to the coolant system. Be sure you never mix coolant and always use distilled water.
