Metal Treatment MT-10® Transmission

Anti-Friction Transmission Additive for Automatic and Manual Transmissions

MT-10® Transmission is an anti-friction metal treatment formulated for use in as a transmission fluid additive to automatic and manual transmissions. It reduces frictional heat and wear in high-pressure metal contact areas, such as planetary gearsets, gears, bushings, bearings, shafts, thrust surfaces, and other transmission components.

MT-10® Transmission treats the metal surfaces rather than the fluid itself. The base transmission fluid continues to provide the fluid film, while MT-10® improves metal surface lubricity in areas where friction, heat, and wear are common concerns.

Key Features & Benefits

  • Reduces frictional heat and wear in automatic and manual transmissions

  • Reduces wear in high-pressure metal contact areas

  • Improves lubricity and load-carrying ability at treated metal surfaces

  • Lowers operating temperatures

  • Reduces governor hang-ups caused by contamination and surface spiking

  • Keeps oil passages, orifices, and ball checks clean and operational

  • Reduces metal particle fallout and debris caused by friction and wear

  • Reduces varnish buildup

  • Supports smoother valve-body operation

  • Eliminates torque converter lock-up chatter where friction or varnish contributes

  • Extends transmission service life by eliminating premature failure when used as directed

  • Promotes smooth, consistent shifting

  • Safe for seals and gaskets

  • For rebuilders: Reduces costly comebacks

  • Treats the metal, not the fluid, by improving metal surface characteristics and supporting protective boundary film formation

  • Clutch-friction compatibility: Raymark SAE clutch testing found no change in friction levels using Dexron II with MT-10® Transmission added at the prescribed ratio.

 
 

How MT-10® Transmission Works

Transmissions operate under demanding conditions. Heat, pressure, metal-to-metal contact, and fluid stress can all contribute to wear and performance issues over time.

MT-10® Transmission is formulated to treat the metal surfaces inside the transmission. Instead of acting as a stand-alone lubricant, it works with the existing fluid. The transmission fluid provides the fluid film, while MT-10® Transmission helps create a protective boundary film that reduces friction and improves the lubricity of metal surfaces in high-load and high-friction areas.

This surface-treatment technique is especially useful in areas where components are exposed to heavy loads, sliding contact, and boundary-lubrication conditions.

Recommended Uses

MT-10® Transmission is recommended for use in:

  • Automatic transmissions

  • Manual transmissions

  • Transmission rebuild applications

Not Recommended For

MT-10® Transmission is not recommended for:

  • CVT transmissions and CVT fluids – CVT systems require specialized fluids with friction characteristics that are different from conventional automatic transmission fluids.

  • Use caution in shared engine, transmission, and clutch fluid reservoirs, including some motorcycles, ATVs, UTVs, snowmobiles, and other powersports equipment. If the wet clutch friction plates contain metal in the surface coating, a friction-reducing treatment may contribute to clutch slippage.

Automatic Transmission Benefits

In automatic transmissions, MT-10® Transmission addresses several common friction-related concerns, including heat, wear, varnish buildup, and torque converter lock-up chatter.

It is designed to protect and condition metal surfaces without interfering with the friction needed for proper sprag and clutch operation.

Manual Transmission Benefits

In manual transmissions, MT-10® Transmission reduces friction and wear in gear, bearing, bushing, and shaft contact areas.

By improving metal surface lubricity, it supports smoother operation and reduces heat generated by high-pressure contact inside the transmission.

Directions for Use

Always follow the equipment manufacturer’s recommendations for fluid type, service intervals, and maintenance procedures.

Automatic Transmissions

Add 8 oz. of MT-10® Transmission through the transmission fluid tube.

For larger transmissions, (i.e., heavy-duty trucks, buses, and other commercial vehicles) use 1.5 oz. per quart of transmission fluid.

Manual Transmissions

Add 1 oz. of MT-10® Transmission per pound of gear lube.

Transmission Rebuilds

MT-10® Transmission can also be used during transmission rebuilds to help lubricate and condition metal parts during assembly.

Need a transmission assembly lube? Try Muscle Penetrating Oil SL-10™, a heavy-duty spray lubricant for pre-lubing and conditioning all metal parts.

Important Application Notes

MT-10® Transmission is intended for use as an additive with compatible transmission fluids. It is not a substitute for proper diagnosis, correct fluid selection, or mechanical repair. Results may vary depending on equipment condition, fluid type, operating environment, and maintenance history. Always follow the equipment manufacturer’s recommendations before adding any aftermarket product.

MT-10® Transmission is compatible with petroleum-based transmission fluids and most common synthetic transmission fluids (often referred to as “over the counter”).

Do not use MT-10® Transmission in CVT transmissions or with CVT fluids.

Use caution in shared engine, transmission, and clutch fluid reservoirs, especially where wet clutch plates contain metal surface coatings.
