GR6 Transmission Pan Gasket for GT-R R35 Transmission Service
The GR6 Transmission Pan Gasket is a sealing component designed for servicing and repair of the GR6 dual-clutch transmission used in Nissan GT-R R35 applications.
The gasket is installed between the transmission oil pan and transmission housing. Its main purpose is to create a reliable sealing surface and help prevent transmission fluid leakage after the oil pan has been removed and reinstalled.
The common OE reference associated with this application is 31397-JF00A. Nissan parts catalogs identify this number as a GR6 transmission oil pan gasket, and specialist GR6 transmission suppliers also list the same reference for GT-R transmission servicing.
The GR6 Transmission Pan Gasket is suitable for professional transmission repair workshops, GT-R specialists, gearbox rebuilders, performance transmission businesses, automotive parts wholesalers and distributors.
GR6 Transmission Pan Gasket Product Information
Basic product information:
Transmission: GR6
Vehicle Application: Nissan GT-R R35 compatible applications
Product Type: Transmission Pan Gasket
Reference Number: 31397-JF00A
Alternative Name: Oil Pan Gasket / Transmission Sump Gasket
Application: Transmission Fluid Service and Gearbox Repair
The GR6 Transmission Pan Gasket should be compared with the original gasket before installation.
Although the GR6 transmission is strongly associated with the Nissan GT-R R35, customers should still confirm the transmission application and gasket shape when ordering replacement sealing components.
Function of the GR6 Transmission Pan Gasket
The transmission oil pan closes the lower section of the gearbox and contains transmission fluid used by the transmission system.
The gasket sits between the oil pan and transmission housing.
Its functions include:
- Preventing transmission fluid leakage
- Sealing the oil pan mating surface
- Supporting proper transmission fluid retention
- Protecting the gearbox from external contamination
- Providing a reliable seal after transmission servicing
A damaged, compressed or incorrectly installed gasket can allow fluid to escape around the oil pan.
For this reason, the GR6 Transmission Pan Gasket is an important service component during transmission fluid maintenance and gearbox repair.
Why Replace the Pan Gasket During Service
When the transmission oil pan is removed, the existing gasket may already have been compressed during previous installation.
A specialist GR6 transmission workshop recommends replacing the oil pan gasket whenever the pan is removed rather than repeatedly reusing the original seal.
Replacing the gasket during service can help reduce the risk of fluid leakage after reassembly.
Typical service situations may include:
- Transmission fluid replacement
- Transmission filter service
- Oil pan removal
- Internal inspection
- Valve body servicing
- Transmission repair
The GR6 Transmission Pan Gasket is therefore commonly required together with other GR6 service components.
GR6 Transmission Service Application
The GR6 dual-clutch transmission requires specialized maintenance and repair procedures.
A professional GR6 service kit can include components such as transmission filters, pan gasket, actuator shims and magnets, showing that the pan gasket forms part of the normal transmission service system.
During service, technicians may inspect:
- Transmission fluid condition
- Oil pan contamination
- Filters
- Magnets
- Gasket sealing surface
- Transmission housing
- Valve body condition
The GR6 Transmission Pan Gasket should be installed only after the oil pan and transmission mating surfaces have been cleaned and inspected.
Reference Number 31397-JF00A
The common reference number for this gasket is:
31397-JF00A
Nissan parts catalogs identify 31397-JF00A as Gasket-Oil Pan for GR6 transmission applications, while specialist GT-R transmission suppliers list the same number as an R35 GR6 pan gasket.
If your product is aftermarket, this reference should be used for compatibility identification rather than describing the product as genuine Nissan.
Customers can compare:
- Reference number
- Gasket outline
- Bolt-hole positions
- Transmission model
- Original component
before purchase.
Transmission Fluid Leakage Prevention
Transmission fluid leakage around the oil pan can occur when:
- The gasket is damaged
- The gasket has become compressed
- The oil pan is distorted
- The sealing surface is contaminated
- Fasteners are tightened incorrectly
- The gasket is installed out of position
Installing a new GR6 Transmission Pan Gasket can restore the sealing interface when the original gasket is no longer suitable for reuse.
However, a new gasket cannot repair a damaged or warped oil pan.
Technicians should inspect both mating surfaces before installation.
Professional Installation Recommended
The GR6 Transmission Pan Gasket should be installed using professional transmission service procedures.
Before installation:
- Remove old gasket material
- Clean the mating surface
- Check the oil pan for deformation
- Inspect the transmission housing
- Confirm gasket orientation
- Align all bolt holes correctly
Fasteners should be tightened evenly according to the applicable transmission service procedure.
Uneven tightening can distort the oil pan or create uneven gasket compression.
After filling the transmission with the correct fluid, the system should be inspected carefully for leakage.
Pan Gasket and Transmission Filters
Transmission pan service is often performed together with filter maintenance.
When the oil pan is removed, technicians have access to components used for transmission fluid filtration and contamination control.
Professional GR6 service packages commonly combine the pan gasket with filters and other maintenance components.
For workshops performing a larger transmission service, combining the GR6 Transmission Pan Gasket with compatible filters and other maintenance parts can simplify the repair process.
Check Compatibility Before Ordering
Before purchasing the GR6 Transmission Pan Gasket, customers should confirm:
Transmission: GR6
Application: GT-R R35 compatible transmission
Reference: 31397-JF00A
Product Type: Oil Pan Gasket
Gasket Shape: Compare with original part
If the original transmission has been modified or uses a different oil pan, customers should compare the physical gasket before ordering.
A clear photo of the original gasket or oil pan can help with product identification.
