Cerma Ceramic Automatic Transmission Fluid SiC ATF | Cerma

Most drivers notice smoother shifts within the first 50–200 miles of driving, as the SiC particles begin bonding to wear sites on clutch friction surfaces and valve body passages. Full benefits typically develop over the first 500–1,000 miles, during which time slippage under load should noticeably reduce and shift quality should continue improving. For severely degraded transmissions (heavy slipping, harsh 1-2 or 2-3 shifts, long shift flare), a full flush rather than drain-and-fill gives faster and more dramatic results because old contaminated fluid doesn't dilute Cermax's effective concentration. Temperature improvements under towing or sustained load are typically noticeable within the first drive cycle after installation.

Yes — in many cases. Cermax is specifically formulated to address clutch slippage caused by friction surface wear, which is the most common cause of slip in high-mileage conventional automatic transmissions. The SiC particles bond to worn clutch disc material and restore the friction coefficient needed for solid clutch pack engagement. However, Cermax cannot fix mechanical failures: broken bands, failed solenoids, burned clutch packs, shredded torque converter internals, or valve body hydraulic failures require physical repair. If your transmission is slipping because the clutch material itself is gone (metal-on-metal contact, heavy metal shavings on the pan magnet, transmission fluid that smells burnt), rebuild or replacement is the appropriate solution — fluid alone cannot restore missing friction material. Cermax is most effective on slippage caused by gradual wear rather than catastrophic failure.

Using Cermax should not void your warranty as long as it meets or exceeds the specification required by your vehicle manufacturer (Dexron VI, Mercon LV, ATF+4, Toyota WS, etc. — see the OEM Specifications table above). Under the Magnuson-Moss Warranty Act (US federal law), a manufacturer cannot void your warranty simply because you used an aftermarket fluid that meets the required specification — they would have to prove the specific fluid caused a failure. Cermax is formulated to meet the major multi-vehicle OEM specs. That said: if your vehicle is still under factory warranty, keep all purchase receipts and service records documenting the specification claim, and consider discussing with your dealer before switching. For older vehicles outside warranty, this is a non-issue.

Yes — Cermax Ceramic ATF is formulated to meet or exceed the performance requirements of Dexron VI (GM), Mercon LV and Mercon V (Ford), ATF+4 (Chrysler/Mopar), Toyota WS and Type T-IV, Honda DW1 and Z1, Nissan Matic series, Hyundai/Kia SP-III and SP-IV, and JWS 3309 for Aisin-built transmissions. This covers the vast majority of conventional automatic transmissions built from the mid-1990s forward across domestic, European, and Asian vehicles. Multi-vehicle ATF formulations like Cermax are designed to serve as a single-fluid replacement for multiple OEM specs, simplifying inventory for shops and fleet operators while providing OEM-level protection. Exceptions: Cermax does NOT replace CVT fluid (Nissan NS-2/NS-3, Subaru CVTF, Honda HCF-2), DCT fluid (VW/Audi DSG, Ford DPS6), or DEX-CVT — these use entirely different base stocks and friction modifiers.

These are two different products that work together but serve different roles. Cermax Ceramic ATF (this product) is the transmission fluid itself — a full synthetic multi-vehicle ATF with SiC built into the fluid chemistry. It replaces your existing transmission fluid entirely. Cerma Transmission Treatment is a one-time concentrated ceramic additive (2 oz for cars/trucks, 6 oz for semi trucks) that's added to your existing transmission fluid to deliver a high-dose SiC application. The treatment is added once and its ceramic bond survives subsequent fluid changes. Which should you use? For maximum SiC protection, many customers use both: install the Cerma Transmission Treatment first for peak SiC concentration, then use Cermax ATF for ongoing service fluid changes. If you're only choosing one, the Treatment gives the highest protection-per-dollar for established transmissions; Cermax ATF is the right choice when you need a full fluid change regardless.

Yes — high-mileage transmissions are actually one of the best use cases for Cermax. As transmissions accumulate miles, clutch friction surfaces wear, seals harden, and valve body passages develop varnish — all of which Cermax is specifically designed to address. The SiC particles target worn friction surfaces, the full synthetic base stock has superior detergency to help clean varnish, and the seal conditioners help revitalize aging elastomer seals. Best practice for high-mileage application: do a full flush rather than drain-and-fill so Cermax works at full concentration; replace the filter and pan gasket at the same time; and drive at least 200–500 miles before expecting full benefits to develop. If the transmission has been neglected for a long time and has heavy varnish buildup, some shops recommend a pre-flush with standard ATF before installing Cermax to maximize the benefit — discuss with your service center.

Most aftermarket transmission additives use friction modifiers that remain suspended in the fluid — PTFE (Teflon particles), moly (molybdenum disulfide), ZDDP, or proprietary polymer additives. These work while they're present, but they have two limitations: (1) they get filtered out by the transmission filter over time, and (2) they leave with the old fluid at every fluid change, requiring constant replenishment. Silicon Carbide works differently. SiC particles permanently bond to metal surfaces through a process similar to heat-induced ceramic deposition — once bonded, they become part of the metal itself and survive subsequent fluid changes. This is why Cerma ceramic technology is sometimes described as a catalyst rather than an additive. Additional advantages of SiC: Mohs 9.5 hardness (vs PTFE's 2–3), 2,730°C melting point (vs PTFE's 327°C, which can thermally degrade inside hot transmissions), and no risk of filter clogging since bonded SiC is no longer in suspension.

Yes — always replace the filter and pan gasket when performing a full transmission fluid change, regardless of whether you're using Cermax or conventional ATF. The transmission filter captures metal shavings, friction material, and clutch debris that accumulates during normal operation. A clogged or saturated filter restricts fluid flow to the pump and valve body, which can cause low-pressure symptoms that look like slipping or harsh shifts — even with fresh fluid. Filter replacement costs $15–$40 for most vehicles and adds 30–45 minutes to the service, but it's essential for the fluid change to actually solve the problems it's meant to address. Top-off service (adding a quart or two to make up for leaks) does not require filter replacement — but any service that drops the pan should include a new filter and pan gasket. For vehicles with sealed transmissions (no traditional dipstick or pan-accessible filter), Cermax still works, but the filter is typically serviced at much longer intervals per manufacturer specification.
