JF016E / RE0F10D OE Part Numbers The Complete Reference

Every week a rebuild shop emails us a number like 31705-28X0B and asks whether it matches the unit on their bench. Nine times out of ten the number is right and the question underneath it is the real one: does the casting revision in my crate match the casting revision this seller shipped? That is a numbers question, and it deserves a numbers answer. This page collects every JF016E part number we rely on in the workshop, shows which ones supersede which, and flags the numbers circulating on marketplace listings that do not belong to this transmission at all.

This is the fourth article in our JF016E cluster, after the complete technical guide, the applications-by-year chart and the fault-code guide. Where those pages explain behavior, this one is built for the moment you already know what you need and just have to order it without a round-trip of wrong crates.

01How to read a Nissan part number on a JF016E

Nissan part numbers follow a strict grammar, and once you can parse it, half the fitment arguments on marketplace listings dissolve on their own.

Two habits fall out of this grammar and they will save you more crates than any fitment chart:

First, the prefix beats the group code. Three suppliers can list three different 31705 numbers under one “JF016E valve body” heading; only the prefix (28X vs 3JX vs X42) tells you which family the casting actually belongs to. Second, the case stamp beats the year plate. Model years split across casting revisions — Gearbox Insider's fitment notes for the 28X0B and 28X0D castings show the 2012–2014 and 2013–2017 windows overlapping, with Jatco running more than one casting behind the same model year — so the number stamped on the transmission case is the only identifier that was actually controlled at the factory.

02The complete 31705 valve body list for the JF016E

Here is the valve body number set as it circulates in the trade today, consolidated from the fitment documentation of the two major aftermarket listings and the OE-new suppliers:

Two honesty notes before you treat this table as gospel. One: the 28X0C revision is thin in public documentation — it appears in supersession chains but almost no listing documents its own fitment window separately, so we treat it as a passing revision rather than a distinct service part. Two: Sussex Autos marks 28X2B as covering both JF016E and JF017E, while Gearbox Insider explicitly warns that the JF017E valve body from related platforms is not interchangeable with the JF016E one. The likeliest reading is that 28X2B is a CVT8-family casting level that crossed both units at the factory, while the service-level valve bodies remain family-specific — but we cannot prove it from public sources, so if your unit is an RE0F10E (JF017E), demand the case stamp before accepting a 28X2B crate.

The practical path at the counter is the supersession chain: 28X0A → 28X0B → 28X0C → 28X0D → 28X2B. In other words, a 2012 Altima crate ordered today will normally arrive stamped 28X2B, because that is the level the OE channel has consolidated onto. What you must not assume is the reverse — that any 28X2B crate automatically fits any CVT8 case. The casting revisions exist because something changed; the case stamp tells you which revision your unit was born with.

03The 31020 assembly number: the stamp that settles arguments

If you remember one thing from this page, make it this: on the JF016E, the complete-transmission number lives in the 31020 group, and the Rogue Sport and X-Trail fitment documentation leans on it precisely because the year plate lies.

The “only” in Gearbox Insider's fitment line is doing real work: the 2017–2019 Rogue Sport with assembly 70X9E takes the 28X0D casting, and other Rogue Sport builds do not. That single sentence is why our workshop replies to every Rogue Sport valve body inquiry with the same request — photograph the case stamp — before anyone opens a crate. The 28X2B-era listings demand VIN verification at checkout for exactly the same reason: the casting-to-case mapping is not a clean function of model year.

This mirrors the pattern we documented for the JF015E, where the oil pan casting code settled what the year plate could not. Jatco's assembly numbering is the company's own traceability system; Nissan's year plate is a marketing convenience. When the two disagree, believe the assembly number.

04The pushbelt: 901074 and the numbers that do not belong

The JF016E drive belt is sold in the aftermarket under the number 901074, consistent across the major marketplace listings for the Altima 2.5 (2012–2019) and Rogue 2.5 (2014–2018) applications. That number traces to the belt maker's part numbering (Bosch/Continental pushbelt tradition), not to Nissan's 31xxx group, which is why it looks so different from the valve body numbers.

Now the part of this section we enjoy most, because it is a worked example of how to catch a bad listing. One of the best-ranked marketplace belt listings under the headline “901074 … Replace OE RE0F10D JF016E” carries this line in its description: OEM Number: 901074, 901089, RE0F11A, JF016E, JF017E. Three claims are stacked there, and only one survives scrutiny:

Stacking a JF017E code onto a JF016E belt listing is not a typo; it is keyword stuffing — the seller wants the listing to surface for both search streams. The tell is always the same: a single line claiming OEM status for numbers that belong to different transmission codes. Our rule in the workshop: if the belt number list cannot be explained sentence by sentence, the listing's fitment claims get discounted, full stop. The same discipline caught the “stepper motor alignment” instructions pasted onto CVT8 valve body listings in our fault-code article — the CVT8 has no stepper motor; those instructions describe the JF011E.

And the boundary rule from the applications chart still applies here: the JF017E uses a chain, not a pushbelt, rated to 380 Nm against the JF016E's 250 Nm belt. There is no belt-and-chain exchange inside the CVT8 family, whatever the listing says.

05The internal filter: 31728-28X0A and its cross-references

The suction filter inside the JF016E carries the Nissan number 31728-28X0A, and it is one of the few parts on this transmission with a genuinely international cross-reference set, which makes verification easy:

Sun Transmissions' application table adds a detail worth knowing before you buy filters in bulk: the 31728-28X0A filter spans JF016E, JF017E and JF018E (RE0F02H) from roughly 2015 onward. So one filter SKU services the belt CVT and both chain CVTs — convenient for stocking, and one more reason the filter number alone proves nothing about which unit is in front of you. For fluid, the JF016E takes NS-3 at roughly 7.9 liters on a full service, as documented in the complete guide.

06Solenoids and sensors: the family with no public OE numbers

Here is an uncomfortable market fact that most parts pages will not say out loud: for the JF016E, the aftermarket solenoid trade has largely stopped printing Nissan numbers. Browse the major listings and the part number field reads “RE0F10D JF016E JF017E CVT8” — a transmission code, not an OE number. One typical kit listing (JCarPart's Serena/Altima application) packs 4 solenoids + 1 control solenoid + 2 pressure sensors with no 31xxx number anywhere in the description.

That is a measurable step down in traceability from the valve body and filter trade, and it has consequences at the bench:

Nissan's own service documentation points the same direction: the TSB flow for the pressure codes (P0776, P0868 and their siblings) ends in replacing the control valve assembly, not in solenoid-by-solenoid substitution, precisely because the bores and the solenoids wear as a matched system. The marketplace's drift away from OE numbers is sloppy, but the service strategy it accidentally converged on — replace the tested assembly — is actually the one Nissan's engineers recommended. Our own JF016E/JF017E valve body page follows that logic: every unit leaves after a full pressure test on the bench, as one verified assembly.

07Numbers that look JF016E but are not

The CVT8 prefix 28X is shared by two transmissions (JF016E and JF017E), and the neighboring JF011E numbers are one digit-difference away. That is the whole habitat where wrong crates come from. The repeat offenders:

One structural note ties this table together: RE0F11A is the number that proves part-number literacy is not optional. Depending on which documentation stream you read, it names either the belt-driven JF015E or the chain-driven JF017E — two transmissions with nothing in common except the brand on the case. When a single code can name two different gearboxes, the casting-level 31705/31020 numbers are the only stable ground, and any seller who cannot state them is working from a catalog, not from units.

08What to photograph before you order — and what we send back

Our workshop's intake for any JF016E inquiry takes two photographs and returns one decision:

1. The case stamp. The 31020-70X9X assembly number on the transmission case. This settles the casting question for Rogue Sport and X-Trail units outright and anchors everything else.
2. The valve body ID line. On the range switch, the QR code block — the first line under the code is the JATCO 5-digit part number, as covered in the fault-code article. This is how a used or previously-replaced unit betrays its real casting level even after the pan has been off a dozen times.

What comes back from us: the confirmed 31705 casting level for your stamp, the matching complete valve body assembly (solenoids mounted, pressure-tested on the bench before it goes in the crate), the 31728-28X0A filter and the 901074 belt if the teardown needs them, and — because the casting question and the calibration question are linked — a reminder of the P17F0 calibration-write step from the fault-code guide, since a freshly installed valve body without its written calibration behaves exactly like a failed one. If the teardown turns out to need more than the valve body, the JATCO CVT hub lists what we stock for the whole CVT8 family.
