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.
