JF016E / RE0F10D Rebuild Kit Contents Every Part Family, Measured

Quick answer: a proper JF016E (RE0F10D, CVT8) master rebuild kit contains paper gaskets, O-rings, lip seals, metal-clad seals, a sealing-ring set, bonded pistons, and the forward and reverse clutch friction and steel plates. The kit itself does not include the belt, the valve body, the pump hard parts, or the filter — those are ordered separately, and skipping them is the most common way a rebuilt CVT8 comes straight back with a P17F0. A complete master kit for this unit runs seven parts families deep; below is every one of them, with real dimensions and the part numbers to match.

We rebuild these units on our own benches, so this article is written from the packing side of the business: what goes into the box, what the aftermarket kit tiers actually differ in, which numbers on a listing are real, and — just as useful — which numbers are decoration. If you have not read the inspection guide yet, start there, because a kit only fixes what the teardown proves is worn.

01The four kit tiers — and what each one actually adds

One of the most confusing things about ordering a JF016E kit is that the same supplier sells what looks like the same kit under five different names. The names are real categories, not marketing fluff. Taking Precision International's catalog (a major US rebuilder supplier) as the reference, the JF016E line looks like this:

The letters in those numbers are not random, either. The K73 prefix identifies the JF016E line; the 900 versus 300 distinction separates the soft-parts overhaul kit from the clutch-included kits; the X suffix means "without bonded pistons"; and -NFG is the supplier's application-family tag. Once you can read that grammar, a catalog page stops being a wall of numbers. It is the same discipline we teach in the OE part-number reference: a number you cannot explain is a number you cannot verify.

02The clutch packs, measured — not described

The JF016E carries two clutch packs: a forward clutch and a reverse clutch. Their friction plates are not interchangeable with anything else in the JATCO range, and the dimensions are the fastest way to check that what arrived in the box is actually for this unit. Here are the published measurements from two independent parts houses, Alltranz (New Zealand/Australia) and Transmida (Lithuania):

That reverse-clutch count deserves an honest note. Alltranz's friction kit lists 2 × reverse friction plates. Transmida lists 3, and valvebody.gr's reverse clutch kit — sold as a complete pack with steels — also lists 3 frictions plus 3 steels, a 4.20 mm thrust plate, a 1.60 mm spring plate, and a 2.60 mm snap ring. Either Alltranz's kit simply undershoots the pack, or the count changed across production. We cannot resolve it from here and we will not pretend to: our own advice is to count what comes out of the drum before you order, and to treat any kit listing that refuses to state plate counts at all as a listing to skip.

03The reverse clutch pack, piece by piece

Because the reverse pack is the one most often ordered as a separate mini-kit, its full bill of materials from valvebody.gr is worth reproducing exactly — every thickness and tooth count is a checkable number when the parts hit your bench:

One detail from the same source that rebuilders will appreciate: the input shaft assembly for the JF016E and JF017E shares its architecture — a 20-spline input shaft, the forward clutch drum, 3 forward frictions, and a 110-tooth planetary ring gear, 179 mm total height. The shared 20-spline input and the shared forward drum are part of why so many listings blur the two units together, which brings us to the problems.

04“JF016E/JF017E kit” — when a shared kit is fine, and when it is not

Several suppliers sell a single overhaul kit labeled for both JF016E and JF017E, and for the soft parts that is often genuinely correct: both are CVT8, both use the same case-sealing architecture, and the rubber chemistry (NBR, ACM, polyacrylate and FKM compounds in the better kits) is common. TRANSWIN's kit page, for one, states the material grades outright and lists both codes with the RE0F10D and RE0F10E numbers — that is the level of specificity you want to see.

Where shared-kit labeling turns dangerous is the friction and steel packs. The JF017E behind the 3.5L V6 engines is a longer, stronger unit (380 Nm, chain-driven in its common RE0F10G form, as we detailed in the three-way comparison), and its clutch pack duty is heavier. A friction kit sold as "JF016E/JF017E/RE0F10E" deserves a specific question before you trust it: which unit is the 178 mm reverse plate actually homologated for? The gearboxinsider master kit page stacks all three codes — JF017E, JF016E, RE0F10E — into one product without resolving that question at all. That does not make the kit wrong; it makes it unverified until you ask.

Our rule, running a warehouse that ships both units: soft kits can be shared; clutch kits get confirmed per unit. If a seller cannot answer within one working day, that answer is the answer.

05Kit application lists — including the ones that are wrong

Kit listings carry long vehicle application tables, and buyers tend to trust them more than they should. Cobra Transmission's JF016E master kit page lists roughly sixty vehicles across seven brands — and while most of the Nissan, Mitsubishi and Renault entries are right (Altima 2013–2018, Rogue 2014–2020, X-Trail T32, Qashqai J11, Serena C27, Teana L33, Outlander, Delica D5, Eclipse Cross, Koleos, Kadjar, Talisman), the table also includes entries that do not belong to the JF016E at all. The Suzuki Kizashi is listed for 2013–2014, but that model ended production in 2013 and ran the JF011E — the CVT7-family unit we covered in its own twelve-article cluster. The Renault Captur and Clio entries for 2012–2013 have the same problem: those years are JF011E applications.

This is not an accusation of fraud — long application tables are usually imported from other kit families with a find-and-replace. But the practical lesson is the same one from our belt-listing teardown in the OE-numbers article: an application table is a claim, not evidence. The evidence is the transmission code on your unit's nameplate or case stamp. We explain how to read both in the nameplate article and in the applications chart.

06Inside the soft-parts kit — what the rubber actually is

A soft kit for the CVT8 typically contains, by category: the oil pan gasket; the valve body conductor plate gaskets; the crank and axle (stub) lip seals; piston O-rings and D-rings; lathe-cut seals; sealing washers; and the metal-clad semi-circular seals for the case openings. Two quality markers separate a serious kit from a repackaged one:

Why the insistence on material names? Because the CVT8 holds line pressure across a 75–90°C design window (we set that out in the inspection guide), and a seal compound that swells in NS-3 will put a rebuilt unit back on the lift with the same pressure-leak codes — P0868, P0841 — it came in with. The fault-code guide maps exactly which leaks throw which codes.

07What a master kit deliberately does NOT include

This is the section that saves money. Even the fullest master kit — frictions, steels, pistons, every seal — leaves out the components that most often decide whether the rebuild survives. Order them with the kit, not after:

The pump bushing line deserves a story. Pilinger, a US rebuilder-house, sells a JF016E package that bundles the master kit with a rebuilt 26E converter, a used-and-tested valve body, a used pulley set, and a used oil pump fitted with a Sonnax pressure-regulator upgrade. Note what they did there: the pump gets the Sonnax treatment, because as our inspection guide documents with the 39,000-mile Altima teardown, the pump flow-control valve bore is the first wear point on this unit. A master kit alone never touches that bore. That is the gap between "rebuilt" and "rebuilt properly."

08The application spread people forget: GM, Suzuki, Dongfeng

Most buyers meet the JF016E through Nissan, but the kit market is bigger than that. The same unit (and its RE0F10F twin, which we flagged in the applications article as a letter-split with documented source conflicts) served: Chevrolet City Express 2015–2018 (the Nissan NV200 in a bowtie), Mitsubishi Outlander/ASX/Delica D5/Eclipse Cross, Renault Kadjar/Koleos/Talisman/Espace, Suzuki SX4 S-Cross and Vitara in selected markets, Dongfeng T70/T90 in China, and Proton's Suprima S and Iriz runs. Two practical notes for workshops in those markets: first, the GM and Suzuki applications mean master kits must be stocked against codes, not against Nissan part numbers — a City Express customer will not search for a Nissan number. Second, the Dongfeng units are the reason Chinese rebuild supply chains (ours included) hold CVT8 stock natively; the unit never left the regional market.

09The order-desk checklist we actually use

Before any JF016E kit leaves our shelves, the order has to pass six checks. Borrow the list:

Check six is the quiet one. Everything mechanical can be perfect and the unit will still log P17F0 within a week if the valve body's calibration was never written after replacement. It is the single most expensive omission we see from shops that buy kits online without a plan.

10The takeaway

A JF016E rebuild kit is not one product; it is a decision about depth. The four-tier system exists because teardowns differ — a reseal job and a full reclutch are different orders of work, and paying for a master kit to fix a leaking pan gasket is as wasteful as resealing a unit whose frictions are down to the steel. What separates a supplier worth ordering from is whether the numbers survive scrutiny: plate counts stated in millimeters and teeth, compounds named by chemistry, application tables honest about their edges, and a sales desk that asks for your code before it asks for your order. That is the standard we hold our own valve body listings and CVT hard parts to — and the standard we suggest you hold everyone else's to, including ours.
