Fix Transmission Problems Without Expensive Rebuilds

Cerma STM-3® Automatic Transmission Treatment uses patented Silicon Carbide (SiC) ceramic technology to restore fast, smooth shifting and protect all metal components inside your transmission. Unlike temporary additives that coat or modify fluid, Cerma penetrates the metal surfaces to form a permanent micro-ceramic matrix — eliminating slippage, hesitation, and rough shifting at the source.

Simply add to your transmission fluid and drive. One-time application. No mechanic required. No disassembly. Works with all automatic transmissions (except CVT/SVT — see note below).

What Cerma Transmission Treatment Does

✓ Restores Fast, Smooth Shifting	✓ Stops Slippage & Hesitation
✓ Eliminates Rough Shifting	✓ Stops Most Seal Leaks
✓ Lowers Operating Temperatures	✓ Extends Fluid Life Up to 4X
✓ Protects Planetary Gears	✓ Prevents Sludge & Varnish Buildup
✓ Protects New Transmissions	✓ Revives Worn Transmissions

Cerma STM-3 is PTFE-free, solvent-free, and environmentally safe. All products are fully insured (US & Foreign).

Common Transmission Problems Cerma Fixes

If your vehicle is experiencing any of these symptoms, Cerma Transmission Treatment can help:

⚠️ Transmission slipping between gears	⚠️ Hard or jerky shifting
⚠️ Delayed engagement when shifting from park	⚠️ Shuddering or vibration during acceleration
⚠️ Transmission overheating	⚠️ Minor seal leaks
⚠️ Sluggish or unresponsive shifting	⚠️ Fluid breakdown and sludge buildup

How Cerma STM-3 Transmission Treatment Works

Cerma's patented STM-3® formula carries pure Silicon Carbide (SiC) particles that penetrate 1–6 microns into the metal surfaces inside your transmission. As you drive, Cerma forms a permanent ceramic matrix within the metal — creating smoother, harder surfaces on gears, clutch plates, and valve body components. This reduces friction, heat, and wear while restoring factory-like shift quality.

Cerma does not modify your transmission fluid. It works directly on the metal surfaces, preventing the formation of performance-degrading sludge and varnish. The treatment is permanent — no re-application needed under normal driving conditions.

Cerma vs. Transmission Repair Costs

Option	Cost	Downtime	Result
Transmission rebuild	$1,800–$5,000+	3–7 days	Full rebuild, significant labor
Transmission replacement	$3,500–$8,000+	3–10 days	New or remanufactured unit
Generic transmission additive	$10–$25	None	Temporary fluid modifier
Cerma STM-3 Transmission Treatment	Under $100	Zero — pour and drive	Permanent SiC ceramic protection

⚠️ Important: CVT & SVT Transmissions

Cerma's warranty and money-back guarantee does NOT cover CVT (Continuously Variable Transmission) or SVT transmissions of any type due to the large number of inherent manufacturer issues with these transmission designs. Cerma STM-3 Transmission Treatment does not fix broken transmissions. Contact your dealer and/or manufacturer for CVT/SVT issues.

Frequently Asked Questions

Q: How do I apply Cerma Transmission Treatment?

A: Simply add Cerma to your automatic transmission fluid through the dipstick tube or fill port. No draining, no fluid change required. Drive normally and the treatment will begin working immediately.

Q: Does Cerma require re-treatment?

A: In most cases, Cerma is a ONE TIME application. The SiC ceramic matrix is permanent and does not wear off under normal driving conditions.

Q: How soon will I notice a difference?

A: Most drivers notice smoother, faster shifting within the first 50–200 miles of driving after treatment. Full ceramic curing occurs over approximately 500 miles.

Q: Will Cerma fix a transmission that's already broken?

A: Cerma treats wear-related issues like slipping, rough shifting, and minor seal leaks. It cannot repair mechanical damage such as broken gears, cracked cases, or failed torque converters. If your transmission has severe mechanical failure, a rebuild or replacement is needed.

Q: Is Cerma safe for my transmission?

A: Yes. Cerma STM-3 is PTFE-free, solvent-free, and environmentally safe. It does not modify your transmission fluid and is completely safe for all seals, gaskets, and internal components. All Cerma products are fully insured.

Q: What is the return policy?

A: We offer 30-day free returns on all purchases. If you are not satisfied, return for a full refund. CVT and SVT transmissions are excluded from the money-back guarantee.

Preventative Maintenance for New & Healthy Transmissions

Cerma isn't just for fixing problems — it's excellent preventative maintenance for transmissions that are still shifting well. Treating your transmission early protects against future wear, extends fluid life by up to 4X, and keeps your transmission running cooler and smoother for years to come. Think of it as insurance for one of the most expensive components in your vehicle.
