Cerma Automatic Ceramic Transmission Treatment — STM-3 Nano Silicon Carbide for Smoother Shifts & Longer Transmission Life
Cerma STM-3® Automatic Transmission Treatment is a one-time ceramic application that restores fast, smooth shifting and permanently protects your transmission against sludge, varnish buildup, and wear. The Nano Silicon Carbide (SiC) particles form a micro-ceramic coating on all metal parts inside your transmission — gears, clutch packs, valve body, and planetary gears.
One application. Permanent protection. No disassembly required.
✅ What Cerma Transmission Treatment Does
- Restores smooth, fast shifting — helps reduce rough shifts, hesitation, and slippage
- Protects against sludge and varnish — SiC ceramic barrier prevents deposit buildup
- Conditions transmission seals — may help reduce minor seal leakage as seals condition and soften
- Extends fluid life up to 4x* — cleaner internals mean fluid stays cleaner longer
- Reduces operating temperature — less friction means less heat (heat is the #1 transmission killer)
- Protects planetary gears — ceramic coating on all metal-on-metal contact surfaces
- Prevents hydrogen embrittlement — protects metal integrity at the molecular level
- Quieter operation — reduced gear noise and vibration
💡 Why it matters: Heat, friction, and varnish buildup are what kill transmissions. Cerma STM-3® addresses all three with a permanent SiC ceramic coating that conventional transmission additives cannot match. Most additives wash out with fluid changes — Cerma bonds to the metal permanently.
🔬 How STM-3 Technology Works in Your Transmission
Cerma STM-3® is not a fluid conditioner or friction modifier — it's a ceramic surface treatment. The Nano Silicon Carbide particles penetrate into the sub-surfaces of your transmission's metal components and create a permanent Silicon Carbide ceramic matrix.
SiC has a Mohs hardness of 9.5 (just below diamond) and a melting point of 2,730°C. Once bonded, this ceramic matrix creates an ultra-smooth, ultra-hard surface on every gear, bearing, and clutch plate — dramatically reducing friction, heat, and wear. The coating survives fluid changes because it's bonded to the metal, not suspended in the fluid.
Cerma STM-3® contains no solvents and no PTFE (Teflon). It is environmentally safe and will not harm seals, gaskets, or non-metal components.
📋 How to Apply
- Check your transmission fluid level — ensure it's at the proper level
- Add Cerma STM-3 Transmission Treatment — pour directly into the transmission dipstick tube or fill port
- Drive normally — the SiC particles will bond to internal metal surfaces during normal driving
- Enjoy permanent protection — the ceramic matrix is now part of your transmission. No reapplication needed
For best results, apply to a warm transmission. No fluid drain required — add directly to existing transmission fluid. Compatible with all automatic transmission fluid types (ATF).

🔬 Technical & Compatibility FAQs
Yes. The Nano Silicon Carbide particles permanently bond to your transmission's internal metal surfaces. The ceramic coating survives fluid changes — when you drain and replace transmission fluid, the SiC protection stays bonded to the metal. No reapplication is ever needed.
Cerma STM-3® can help with symptoms caused by friction, heat, and surface wear — which often underlie slipping sensations, delayed engagement, and some friction-related diagnostic codes. However, Cerma is not a mechanical repair product. If your transmission is throwing codes related to internal mechanical failure (broken bands, failed torque converter, damaged clutch packs, failed solenoids), Cerma will not fix those issues. For transmissions with moderate wear and early slipping symptoms, many customers report significant improvement. For severe problems or codes like P0700, P0730, or P0751, have your transmission professionally diagnosed before applying Cerma.
Yes. Cerma STM-3® is compatible with all automatic transmission fluid types — Dexron, Mercon, ATF+4, Type F, and synthetic ATF. The treatment bonds to metal, not fluid, so your fluid type doesn't affect the ceramic protection. It's also compatible with manufacturer-specific fluids including Toyota WS, Honda ATF-DW1, Nissan Matic, and Mopar ZF 8/9-speed fluids.
Yes — older automatics are often where Cerma delivers the most dramatic improvements. Classic automatic transmissions like the GM TH350 and TH400, Ford C4, C6, and AOD, and Chrysler TorqueFlite A727 and A904 were built to last but typically show wear after 150,000+ miles — slipping between shifts, harder engagement into reverse, or delayed 1-2 shifts. Cerma's SiC ceramic matrix bonds to worn clutch pack surfaces and bearing surfaces, restoring smoother operation and extending service life significantly. For owners of classic trucks, vintage cars, and restoration projects, Cerma is often a fraction of the cost of a rebuild and can add years of reliable service.
Yes, and this is actually an excellent time to apply. After a professional transmission flush or fluid change, your transmission has fresh fluid and clean internals — ideal conditions for the ceramic bonding process. Add Cerma to the fresh fluid through the dipstick tube or fill port, then drive normally. The SiC particles will begin bonding to clean metal surfaces immediately, with full ceramic matrix development over the first 1,000–3,000 miles.
No. Add Cerma STM-3® directly to your existing transmission fluid through the dipstick tube or fill port. No fluid drain or flush required. For best results, apply to a warm transmission after a short drive — this helps the SiC particles distribute throughout the fluid and reach all internal components.
Cerma STM-3® does not modify your transmission fluid — it treats the metal surfaces. Under the Magnuson-Moss Warranty Act, aftermarket products cannot void a manufacturer's warranty unless the product itself causes the damage. That said, we recommend consulting your dealer if you have specific warranty concerns. Note: The Cerma money-back guarantee does not apply to CVT or SVT transmissions.
Most drivers notice smoother shifting and reduced transmission noise within the first 100–500 miles of driving after application. Full ceramic bonding develops over the first 1,000–3,000 miles. The protection is permanent once bonded. Older or worn transmissions often show more dramatic improvements than newer, well-maintained ones.
