Unhappy with transmissions temps over 135° C when driving the GT-R on the track, Garage Saurus have set about development of a prototype Nissan GT-R transmission cooler. The GT-R transmission is fitted with a rather diminutive cooler from the factory standard. Garage Saurus plan to replace this with lines to a larger cooler. As yet the size, mounting location and design of which is still up in the air.

What is done so far is design and fabrication of the first GT-R transmission oil cooler adapter plate from billet aluminium. This will eventually connect to a cooler using quality Earls fittings.

Quite a few GT-R owners have already expressed concern over various oil temps at the track so I’m sure many of us will be following the development of this.
