How To Fix A 2021 Gtr Transmission

If you lot were a fan of the Nissan GT-R during the R32 – R34 era, you were probably every bit surprised every bit we were to discover the R35 generation would lose its transmission transmission and clutch pedal.

For us, that initial disappointment faded rapidly once the Nissan GT-R R35's GR6 manual showed not simply its extremely loftier performance, but its immediate responsiveness.

The GR6 is built by Nissan's subsidiary Aichi Kikai using engineering science developed by Borg-Warner. Borg-Warner supplies dual-clutch transmission to many other brands but the Nissan GR6 is very unique in its design, operation, and maintenance.

The GR6 is a rear transaxle for improved vehicle weight distribution. The manual is mounted towards the rear of the car and contains the rear differential unit. Information technology is continued to the engine using a torque tube and connects to the front differential via a propeller shaft. These specifications mean the Nissan GTR with GR6 transmission requires white-glove maintenance.

Caring for Your Transmission Is Central

Starting time, the GR6'southward wet clutches are lubricated past the manual fluid, and this fluid eventually becomes dirty. With the resulting clutch disc vesture, whatsoever replacement fluid must be a close match for the original to ensure proper clutch functioning. Dirty, worn fluid not only loses its ability to properly lubricate the system, merely in the GR6 it also can create problems with the various solenoids that control shifting and clutch operation.

Nissan's original recommendation was to modify the transmission fluid every eighteen,000 miles. Afterward model year GT-Rs came with a higher 36,000-mile service interval recommended. For all model years, transmission fluid that has seen temperatures above 248 degrees Fahrenheit should be changed every 3,000 miles. Fluid that has been above 284 degrees F should be changed every bit soon every bit possible.

Because reaching the 248-degree mark on the street is tough fifty-fifty in heavily modified GT-Rs , immediate oil change after reaching this threshold is mostly a problem for drivers who frequent track events. If you find your GR6 transmission reaching 230 degrees or college during whatever kind of street driving, contact the states for diagnosis considering this level is not normal. Getting it to usa quickly will likely help you avoid a major repair.

We service the GT-R transmission by dropping the pan for several reasons. Nosotros aim to:

drain out as much fluid as possible
clean away whatever debris
bank check & clean the pan magnets to ensure there is not excessive wear textile
replace the two main filters.

The time & mileage intervals for fluids and filters volition vary depending on the GT-R in question.

We encourage owners to accomplish out to us for personalized recommendations. While careful maintenance is the cloak-and-dagger to your vehicle's performance and longevity, drivers should avoid unnecessary service. Every GT-R transmission service includes reading the temperature history to check for any events in the two higher temperature ranges. It also includes setting the clutch capacities and touchpoints after the transmission is filled with fresh fluid.

When Worn Pistons Make Trouble

Our years of experience servicing luxury Nissan sports models have taught us that GR6 shift forks are moved by a set of pistons that are prone to premature wear on 2009-2011 CBA R35s. Worn pistons prevent proper shifting, and, one time the piston wears likewise far, the magnets in the piston movement out of the position sensor's range and allow the shift fork to move as well far. Many broken shift forks are the consequence of this premature piston wearable.

After much exploration, we've institute that DBA GTRs accept clips added to keep the piston properly located and forestall wear. Jack'due south Transmissions offers clips that tin can be easily added to CBA transmissions in one case the valve trunk is removed. We offer this upgrade as a preventative measure and recommend it whenever the valve body is out.

All Critical Oil for the Nissan GT-R GR6 Manual

Another special consideration of GTR buying is its specially formulated oil. The 18-carat Nissan R35 Special Transmission Oil 999MP-GTRT00P was originally sold for around $90 per liter. When stock transmission needed x liters for service, specialized oil companies saw an opportunity to create a more affordable alternative every bit soon as the GT-R hit the market.

Two options provide savings. Motul DCTF is a popular choice although it is partially synthetic. More, we take noticed slightly higher transmission temperatures with DCTF versus the original Nissan fluid. Our recommendation is Torco DCT for stock GR6s or those that are built to Stage 1 or 2 levels. Torco'south 100% synthetic fluid runs cooler than any other nosotros have tested and provides excellent wear protection and cleanliness. The fact that it's less than one-half the price of Nissan's R35 Special Transmission Oil prices is a nice bonus.

Stage iii and above transmissions typically run specialized Dodson fluid depending on the recommendation of the transmission builder and the driver's mix of street, strip, and circuit driving.
