Common GR6 Problems
What's wrong with your R35 transmission?
The R35's dual-clutch GR6 has a handful of failure modes we see often. The symptoms:
Shuddering on take-off
Likely cause: Worn clutch packs, contaminated transmission fluid, or low fluid pressure
Slipping under load
Likely cause: Clutch packs at end of life, solenoid issues, or tune outrunning the clutch capacity
Skipping or missing gears
Likely cause: Valve body wear, solenoid faults, or mechatronic issues
Harsh or jerky shifts
Likely cause: Clutch fluid degradation, worn clutch packs, or shift calibration drift
Hard launch failures
Likely cause: Launch control programming, worn clutches, or supporting hardware not rated for the launch
Transmission fault codes
Likely cause: Sensor faults, mechatronic issues, or internal hydraulic failures
Not sure what's wrong? Bring it in. GR6 diagnostics is what we do. We'll scan, pressure-test, road-test, and quote only what your box actually needs.

FAQ
Common questions
- How much is an R35 transmission service?
- $1,395 for parts and labour. That covers Motul Multi DCTF fluid, a genuine Nissan pan filter, inline filter and pan gasket, a Dodson pan magnet kit, and Dodson TSB clips if your car doesn't have them yet. We need the car for the day.
- How much does a GR6 transmission rebuild cost?
- Depends on what's needed. A clutch pack replacement costs significantly less than a full rebuild. After diagnosis we'll give you a written quote with no surprises.
- How long will my R35 be off the road?
- Depends on the work. A GR6 service is a day. Clutch pack replacement is a few days. A full rebuild takes longer. We'll confirm timing once we've diagnosed your box and ordered any parts needed.
- My GR6 is shuddering — does it need a rebuild?
- Not necessarily. Shuddering can come from contaminated transmission fluid, low clutch pressure, or worn clutch packs. We diagnose before quoting work. Sometimes a fluid service and adaptation reset clears it up.
- Can you check the gearbox before I buy an R35?
- Yes. Our pre-purchase inspection includes a GR6 health check, an ECU and TCU read, and a road test. You get a written report before you hand over any money. R35 pre-purchase inspection
- Do you work on R35s from regional Victoria?
- Yes. We see R35 owners from across Melbourne and regional Victoria. We're at 8-10 Molan St, Ringwood VIC — easy access from EastLink and the Eastern Freeway.
- Do you offer a warranty on your work?
- Yes. We warranty our parts and labour on all GR6 work. The factory warranty side depends on your car's age and history. We'll cover that in writing before any work starts.
- Can I tow my R35 to you?
- Yes. We can arrange transport if your R35 isn't drivable. Or come in via tow truck directly. Call ahead so we can have a bay ready.

"Revzone did a great job fitting my cold air intake and tuning my VB WRX. Car is much more responsive down low and is perfect for a daily driver. Jeff was extremely helpful and insightful through the whole process and I would recommend to anyone looking for a tune of their car!"

"I was lucky enough to come across Revzone many years ago now, and I will continue to be their valued client. To get great customer service, quality and value for money is not very common in any industry, let alone the car industry. Thank you for your help over the years. Brian"

"Really happy with the upgrade! Had my exhaust, suspension, and Stage 1 tune done on my 2017 CVT here. The car feels more responsive, sounds great, and handles much better. The team was professional, knowledgeable, and kept me informed throughout the process. Highly recommend if you’re looking for quality work and reliable advice."
