Willlall Racing Transmission Cooler Lite Edition – DIY Kit
While some may feel the need to opt for a full blown GR6 transmission cooler with fancy extended sump like the Willall Racing WR35TC there are others that may not need to go to that expense. Maybe you just track the car occasionally or just want to DIY and keep it simple at the same time. Willall Racing’s WR35TC-Lite will close that gap at a fair price which is a welcome addition to the aftermarket.
WR35TC-Lite is a mid-mount cooling solution mounting in front of the rear exhaust section so that its air ‘signal’ is not polluted by hot exhaust gasses. This is a proven cooling location that we use with our WR35DC rear differential cooler, and testing so far has shown that at within a second of Carerra Cup lap pace (a good worldwide reference line) and 75 degree ambients it is possible to consistently reduce transmission temperature by 15F-25F consistently and keep the GTR transmission temperature out of the red.
Technical aspects of WR35TC-Lite are as follows
- German gear style VDO 6 litre per minute transmission pump
- 13 row oil cooler core
- 500F lines with crimped fittings
- CNC mounting bracket (anodised) and cooler plate
- High durability hose clamps
- Tapered lock fitting for the stock transmission pan (comes with professional seals)
- Wiring loom integrated with relay and operation switch (with light)
- Anti abrasion wrap for the cooler lines
The kit is priced at the $1295 mark and is available now from Willall Racing dealers worldwide…

SouthSide Performance Launch Front Mount Transmission Cooler for Nissan GT-R
More and more options for cooling off your GT-Rs GR6 DCT are making their way to market every month it seems but there’s been some quiet murmurs amongst owners that some aren’t performing quite as expected. SSP hope to change that with their new kit that offers track proven cooling performance to back it.
The kit includes a high quality Setrab core fed by a thermostat controlled pump, and a billet extended DCT oil pan that effectively increases transmission fluid volume.
Looking at availability starting June 7th, pre orders up now and the price is $2499.

GReddy DCT Transmission Cooler for Nissan GT-R Debuts at SP Engineering
Just launch days ago, GReddy has shipped what is one of the first units to official US GReddy dealer SP Engineering who wasted no time in fitting it up on their workshop SPE900 project GT-R. The kit is typical of the quality of product coming out of GReddy / Trust these days and fitted up great with amazing attention to detail at every step.
The core is 13 rows in size and 299×185.4x50mm in dimensions, it’s supplied with a FRP air duct to supply air from the front bumper and all hoses, hard lines and fittings needed to install it. It’s thermostat controlled to bypass the factory transmission oil cooler when it’s operating to maintain transmission fluid pressure. This also helps maintain the fluid temps independently of the engine coolant temperature.
It’s priced around the $2,495 mark minus the optional windshield reservoir tank. More photos at the SP Engineer blog and a link to the SP Engineering store is below…

GReddy Trust Intercooler Spec-R HG T29 Kit for Nissan GT-R
GReddy have officially released and priced their latest offering in the cooling arena for the Nissan GT-R, their Spec-R HG T29 Intercooler Kit. The kit comes in two forms, the full kit and the conversion kit and is designed to replace not only your OEM intercoolers with a joined core crossover type intercooler but much of your intake and intercooler piping as well.
The full kit features polished hard piping kit to support Trust pod filters in replacement of the OEM airboxes, polished hard piping kit to replace the intercooler piping, silicon host joiners, GReddy blow off valves and other minor but very important items such as brackets and hoses. The full kit retails at 388,500 yen in Japan.
The conversion kit assumes you already have the Trust intake piping kit so removes the intake pipes and the blow off valves. It saves a little money and goes for around 312,900 yen in Japan.
With either kit, you’re crossing the airflow over so you should need to take into account that the airflow sensed by the left MAF (mass airflow sensor) will now be fed to the ECU to control the RIGHT throttle. So most people recommend extending the MAF wiring harness to correct this when using this type of intercooler. I do not see a mention of that being included in either of these kits so it’s something to be aware of.

Willall Racing Transmission Cooler Pump Upgrade for WR35TCF
For maximum efficiency when using Willall’s front mounted transmission cooler, they’ve designed this pump upgrade that will replace the supplied VDO item. This Propump, as they’ve called it, manages to circulate the entire volume of transmission fluid through the front mount cooler every 40 seconds. In testing, the guys have found this unit can assist lowering temps by as much as 35 – 55 degrees F.
The kit will ship with all components necessary to fit it including the high performance pump assembly, control electronics and CNC machined mounting hardware.
To spec out a new WR35TC-F with the Propump will run you an additional $395. Existing WR35TC-F owners should stay tuned and expect an announcement on what they can do for an upgrade some time in April.

HKS Dual Clutch Transmission Cooler for Nissan GT-R Released
HKS have announced their own transmission cooler for the Nissan GT-R this week just prior to Tokyo AutoSalon. The front mounted oil cooler design goes up against some already strong entries in the market, one from regional affiliate HKS Kansai. The difference here is that HKS have seemingly chosen to directly cool the transmission fluid by way of pumping it through a front mounted, 15 row, oil cooler. The core dimensions of the cooler are 220mm x 220mm x 48.5mm.
In contrast, the HKS Kansai item cools the engine coolant that the GT-R pumps through the transmission to cool it before it reaches the transmission by way of a water cooler in the same location. Which is best?
Anyways, the core is fed cold air from the front bumper by way of ducting that mirrors the ducting to the factory oil cooler, a slight modification to the standard front bar to open the airflow to this duct will be required.
In testing at Fuji Speedway, over a 15minute full on session, HKS saw the transmission temp level out at 127 degrees with the HKS DCT Cooler fitted. In comparison, with the standard setup they had to abort the run at the 11 minute mark as the transmission fluid temp hit 135 degrees celsius and showed signs that it would continue to climb.
Cooler transmission fluid temps increase fluid lifespan, offer smoother shifts on the track and decrease the chances that you’ll hit the inbuilt safety limp mode of the TCM. One other side effect of cooler transmission temps that HKS noticed while testing is that the engine coolant sees a subsequent drop in temperatures as well. I guess it’s job is made a little easier by not having to cool a 135 degree gearbox down.
Theres a few other details to note, and we should be able to clear up all the how’s and why’s on Friday at TAS.
Price is set at 262,500 yen in Japan.

Willall Racing WR35DC Rear Differential Cooler
Another Australian innovation to show you guys today, Willall Racing’s latest addition to their cooling and oil related product lineup, the WR35DC rear diff cooler. Designed from the ground up with circuit driven Nissan GT-Rs in mind, the kit is designed to be a direct bolt on, no nonsense required fit onto your Nissan GT-R.
Featuring a 13 row oil cooler, CNC machined brackets, oil pump, high pressure hoses and fittings as well as every fastener you’ll need to bolt it straight on. The kit also has a neat replacement diff cooler air scoop and jack point adapter to ensure you can continue to service the car via the rear diff jack point as per normal without concern that you’ll break something.
One other benefit of going with the WR35DC is the integration and compatibility with the existing WR35TC transmission cooler. If you have this item or are looking to buy it at the same time, you’ll find that Willall can ship with the require brackets and looms to mount them both without issue.
Priced at $1,495 it’s available from your Willall Racing distributor now, test data should be made available shortly.
