After already finding success in protecting a large number of tuner and end user GT-R gearboxes from accelerated wear, Willall Racing are releasing another product that goes even further. Named Willal Racing Transmission Fluid Victory Specification (WR35TMVS), this is a DCT fluid that shares the same proven formulation of the WR35TM with extra protection for those who need it. Whether its launches at the drag strip or bags of power from upgraded turbos, this fluid sets out to protect your precious gearbox internals.

The key to the WR35TMVS is it’s proactive cushioning between gear faces by way of a solid boundary additive.

Think of it as millions of tiny plastic balls in each 10L container of WR35TMVS that forms a plasticised barrier between the gear contact faces, bringing down the shock of gear engagement at high power and torque, whilst still allowing the GTR transmission to shift at its super-rapid factory set timing interval …

“The GTR transmission is at most risk when being rapidly loaded, thats means shifting at full power while the car is light over a crest or partially airborne, or in the case of some of the 1000hp super GTRs being built simply from shifting at full throttle. WR35TMVS addresses these all important issues and offers that extra layer of protection the GTR needs in these extreme applications whilst still retaining the same excellent base clutch friction properties of WR35TM and wide extended service intervals. – Willall Racing

Sounds just crazy enough to work to me. Solid data on this new lubricant is due to be released in January which will coincide with it’s launch at distributors worldwide.

Each 10L container of WR35TMVS suits one GT-R for one complete fluid change with a little extra for a top up. Included in the price is trans fluid lab analysis for the next 12 months to help you plan your service schedule with hard science data to back it.

No exact pricing is available yet but keep your eyes peeled and we’ll let you know soon.

With so many exhaust options on the market today, it can be difficult to find the right mounting for a big radiator at the rear of the car. Unless you go to a loud / race straight through design or a single sided exhaust you may run into clearance issues with a standard Willall Racing Transmission Cooler.

Willall Racing have done their homework here though and come through with a solid solution. A front mounted cooler for those who cant or don’t want to rear mount the radiator.

Utilising the regular WR35TC transmission sump extension, extended lines, updated radiator type and a modification to the GT-Rs front bumper this kit can be fitted to any Nissan GT-R. Front bar removal is not necessary and can be done with it in place on the hoist.

Available now from Willall Racing and their distributors.

SouthSide Performance have now backed up their previous transmission strengthening clutch upgrades with a new transmission cooler codenamed the GR6-TC230RS.

It may appear cryptic to you but when you consider that the SSP transmission cooler’s aim is to keep your transmission fluid around the 230 degree F region then it all begins to make sense.

This transmission cooler comes with an extended sump billeted from 6160 aluminum. The sump is is also finned to increase the surface area and thus offer cooling properties by itself. That’s not all though, the transmission fluid is pumped by a high volume pump through a bar and plate cooler. Two electric fans assist air moving through the cooler to assist when outside airflow is minimal.

Priced at $3,199 the SSP transmission cooler should be available around the end of April 2009. The full press release can be read after the jump…
