RE7R01A JR710E Transmission Filter & Oil Pan Gasket Kit

Owners of an Infiniti G37, Q50, Q60, M37, FX35 or a Nissan 370Z with the seven-speed automatic usually land here for one of two reasons: shifts have gone slow or rough, or the car is past 60,000 miles and nobody has touched the fluid. This kit gives you the internal filter and the oil pan gasket for the RE7R01A, which JATCO builds as the JR710E (with a JR711E variant). It is a drop-the-pan job, since this transmission has no dipstick and no external filter.

What the filter does in an RE7R01A

The RE7R01A is a longitudinal, rear-drive seven-speed that sits behind the VQ V6 in the G, M, EX/QX50, FX/QX70 and Z. All fluid the pump sends to the valve body and its solenoids passes through this filter first. The solenoids hold clutch pressure to tight tolerances on every shift, so a filter loaded with clutch dust either starves the pump or lets debris reach the valve body. Either way the computer starts adapting around a problem it cannot fix, and the shifts get worse.

Symptoms of a dirty filter or tired fluid

• Slow engagement into Drive or Reverse, especially first thing in the morning
• A whine from under the car that tracks engine speed
• Firm or lazy 1-2 and 2-3 shifts, or a bump on downshifts coming to a stop
• Dark fluid with a burnt smell when the drain or check plug is pulled
• High transmission temperature readings on a scan tool during towing or track use

Shift complaints on this transmission are also commonly caused by the valve body and its solenoids. If the fluid looks clean and the symptoms stay after a service, the RE7R01A solenoid kit or a complete RE7R01A valve body is the next place to look.

How to confirm before buying

Pull a sample and look at it. Bright red and clean means the filter is not your problem. Dark brown, burnt, or full of glitter means service it now and inspect the pan. Our guide to flare versus slip will help you tell a pressure problem from a worn clutch, and a scan tool that reads transmission temperature and stored codes is worth having before you order anything expensive.

Fitment

The listing covers Infiniti Q50 and Q60 2014-2021, Q70 2014-2019, Q70L 2015-2019, QX50 and QX70 2014-2017, Q40 2015, G37 and FX37 2013, M37 and M56 2011-2013, EX35 2011-2012, FX35 2009-2012, M35 2009-2010, and the Nissan 370Z 2015-2020. Be careful at the edges of that list. JATCO lists the V8 and diesel FX/QX70 and the V8 Fuga (the M56 in North America) on the heavy-duty RE7R01B, not the RE7R01A, so M56 and V8 owners should match the old filter before installing. Aftermarket kits reference Nissan number 31705-X185D; that 31705 family is the transmission control valve number, which is why a dealer may tell you the filter is not sold on its own. Hybrid models were not checked for this kit. Compare against your old filter or send us your year and VIN. More service parts are in our rebuild kits and service parts section.

Install notes

• Drain the fluid, drop the pan, and pull the old filter straight off the valve body. Make sure the old seal comes out with it.
• Clean the pan and magnet, seat the new filter fully, and lay the new gasket dry. Torque the pan bolts evenly in a cross pattern.
• Infiniti specifies Genuine NISSAN Matic S ATF and warns that other fluids can damage the transmission. Our Matic S 6-quart kit covers a pan service. AWD models use Matic J in the transfer case, not in this transmission.
• Refill through the fill port with the 7-speed fill adapter, then set the level at the specified fluid temperature with the engine running. Our fluid change guide walks through the basics.

Does the RE7R01A actually have a filter?

The kit supplies an internal filter that mounts on the valve body and is only reachable with the pan off. Some dealers tell owners the RE7R01A has no filter, because the Nissan number aftermarket kits reference belongs to the control valve family. Compare the filter in this kit to the one on your valve body when the pan is down.

Which fluid do I need after installing this kit?

Genuine NISSAN Matic S ATF. Infiniti warns that using a different fluid can hurt driveability and damage the transmission. Do not use Matic J, which is the transfer case fluid on AWD models.

Will this fit my M56 or a V8 QX70?

Possibly not. The V8 and diesel versions use the heavy-duty RE7R01B. Compare your old filter to the one in this kit, or send us your year and VIN before installing.

Do I need sealant on the pan gasket?

No. The gasket goes on dry against clean, oil-free flanges. Tighten the pan bolts evenly in a cross pattern so it seals without distorting.

Is a relearn needed after the service?

A filter and fluid service does not normally require a relearn. If you also replace solenoids or the valve body, follow the factory procedure for the transmission control module.
