Willall Racing are taking a different tact in the field of transmission cooling. While thus far the GT-R’s GR6 dual-clutch transmission has been adapted to external cooling via a simple billet adapter and radiator, Willall have taken to engineering an entire sump replacement and more.
We’ve only been given details on the GR6 sump replacement so far so lets dive into what we know.
The Willall Racing Transmission Cooler (WR35TC) comes with an anodised billet aircraft quality aluminium transmission sump. The computer modelled and 5-axis CNC’d sump is deeper than the standard sump allowing for a larger oil volume. The WR35TC sump is also finned allowing for a much larger surface area for heat to both transfer out of the oil and for air to then carry that heat energy away.
The WR35TC provides removable access ports to give access to the transmission magnets which should be cleaned during a transmission service. It also bolts straight on using the OEM gaskets.
This is part one of the cooler, the primary cooling mechanism is yet to be revealed. To see what heat exchanging path they will follow check back soon when we have part 2 of this report.

Willall Racing have already made interesting developments in the GT-R world with their transmission and differential fluids. They’ve now got an alternative fully synthetic high performance 10W-60 motor oil for the GT-R developed on the track designed to offer superior protection at high engine temperatures and to reduce the tendency for the GT-R to go through oil between changes.
Other benefits of the WR35MO engine oil include:
- Tested and developed in an R35 GTR for R35 GTR applications
- VR38DETT oil consumption eliminated
- Much greater oil film strength at 100 degrees than factory fill
- Plasma bore protection improved via increased oil film strength
- Cooler oil temperatures due to friction reduction
- Increased bearing life
- Stable under wide environmental conditions
- 100% Synthetic
WR35MO engine oil is available now and sells for $330 USD per 10 litre container including shipping to your door. Get the order form at the link to the Willall Racing website below and check out the full press release after the jump.

Following on from their amazing work developing a solid boundary transmission oil upgrade for the Nissan R35 GT-R’s GR6 transmission – WR35TM – Willall Racing have developed a fluid upgrade for the GT-R’s limited slip differential.
Willall Racing have today released this diff fluid, known as, WR35DF, and have published a press release containing the details which we have below. A technical analysis of the reasons behind development of the WR35DF follows after the jump including magnified images detailing the Nissan standard differential fluids performance.
WILLALL RACING WR35DF Differential Fluid – December 2008
Application: Nissan R35 GTR Front and Rear Differential Assemblies
WR35DF is a full synthetic Limited Slip Differential fluid that has specifically developed and tested in the R35 GTR differentials. Engineered to drastically reduce the amount of binding suffered in the rear differential during slow speed cornering WR35DF utilises unique Solid Boundary technology to smooth rear differential chatter and drastically slow the wear process that occurs in these differentials.
Top level protection is guaranteed for the front R35GTR differential which runs a critically low quantity of fluid from the factory and can suffer from extreme temperature rise under spirited driving conditions. The low friction of WR35DF reduces temperature of the front differential dramatically and provides smooth and quiet operation under all conditions.
Grade: GL5 Full Synthetic 75/140
Additives: Solid Boundary protection pack
Application: Nissan R35 GTR Front and Rear Differential Assemblies
Packaging : 1 litre container (Complete Fill for front and rear differentials 3 litres)
Shipping: Worldwide
Cost: $70 USD per litre, $270 USD for 3 litres delivered anywhere in the USA
Available: NOW
