ProTecta Automatic Transmission treatment 10 Ounce Bottle
Feature
NOT FOR USE IN CVT TRANSMISSIONSTransmission Shifts Like New
Lowers Operating Temperature
Eliminates Torque Converter Shudder
Frees Sticking Valves
Description
For a smoother ride and a longer-lasting transmission select ProTecta synthetic Transmission Treatment. ProTecta will restore friction and anti-shudder control, reduce sludge and formation of deposits, and improve wear protection. With the popularity of the over drive transmission, today's drivers are experiencing transmission torque converter shudder. Torque converter shudder is caused by the transmission boost valve sticking and pre-mature oxidation of friction modifiers in ATF. Protecta keeps working when factory fluids have lost their effectiveness. ProTecta enhances the fluid life with a synthetic formulation for maximum transmission performance. Protect Your Investment! Extend the Life of Your Automatic Transmission. Recommended for use in most all automatic transmissions and 4 x 4 transfer cases. Automatic transmissions normally operate at temperatures of 170-200F and start up at temperatures as low as -40F. ATF's must flow easily at low temperatures, be highly resistant to thermal and oxidative degradation at high temperatures, be non-corrosive toward all transmission components, be resistant to foaming and have specialized friction and anti-wear properties. ProTecta utilizes special friction modifiers to provide smooth shifting and protects against heat especially during towing. A lot has changed with the automatic transmission in the last several years. Computer controlled shifting and front wheel drive. OEM's are rapidly turning to installing synthetic ATF in their luxury vehicles. ProTecta with its unique synthetic formulation provides improved protection to meet the demands of today's sophisticated transmissions.4.

Only protectant that increases the fluid's ability to transfer heat / Protects new seals and permanently restores older seals to a like-new condition, without adverse side effects
Description
LUBEGARD AUTOMATIC TRANSMISSION FLUID (ATF) PROTECTANT is for use in all automatic transmissions and manuals requiring an ATF, including heavy duty transmissions, such as Allison. Use with all synthetic or mineral based DEXRON, MERCON & OEM (Original Equipment Manufacturers) ATFs (except Ford Type F ATF & CVT applications). Lubegard controls heat and is especially effective in todays hotter running front wheel drive vehicles. It contains LXE (Liquid Wax Ester) Technology and their derivatives, base oils and conventional additives. Lubegard is designed to raise the thermal and oxidative stability level of automatic transmission fluids, so when it operates at elevated temperatures, it does not thin out and pyrolize, burn or react with oxygen and form deposits. The use of LUBEGARD ATF Protectant will not cause clutch friction upset or slippage. DIRECTIONS FOR USE: For normal applications, add 1 oz. (29.6 mL) per quart (Liter) of ATF to the total transmission capacity (including torque converter) with motor idling in park. Do not overfill.5. Sea Foam TT-16 Trans Tune Transmission Additive - 16 oz.
Feature
Does not harm or swell seals or alter the viscosity of the transmission fluidReduces rough or erratic shifting
Removes damaging moisture
For automatic transmissions, power steering systems and industrial or agricultural hydraulic systems
Description
Trans Tune is a petroleum based product comprised of three specific oils, blended in just the right proportions to safely clean varnish deposits in transmission, power steering and hydraulic pump components. Trans Tune is compatible with all commonly used petroleum and synthetic based hydraulic fluids used in automatic transmissions, power steering systems, marine transmissions, agricultural equipment and industrial hydraulic lifts. Trans Tune reduces rough or erratic shifting by dissolving varnish that contaminates transmission valve bodies, bands, governors, pumps and passages. Trans Tune makes the perfect system flush for transmissions, power steering and hydraulic pumps, removing damaging moisture and deposits that impair system performance.6.

XADO Revitalizant EX120 Conditioner for Automatic Gearbox & CVT Tiptronic Transmission Oil Treatment Additive (Box, Syringe 8 ml) Protectant Fluid - Restore Your ATF Metal Parts from Wear (Automatic)

Rebuilds And Restores Metal Parts And Protects Them From Future Wear, Reduces FrictionEliminates Surfaces Defects. Protection From Extreme Friction And Heat
Stops Transmission Shudder and Reduces Noise, Vibration
Increases Performance Reliability And Prolongs Service Life Of Control Gears
Universal for Automatic, CVT, Tiptronic, Manumatic, Semi-Automatic Transmission
Description
EX120 starts repairing scratched and worn metal as soon as it is added to an automatic transmission. Revitalizant acts as a catalyst for rebuilding and repairing metal in areas of excessive thermal energy. It activates the absorption process of carbon through the surface layer which results in the formation of metal carbides. Revitalizant rebuilds parts at a molecular level, atom-by-atom. A new durable protective coating is formed with the help of carbides and metal particles. Diffusion of the protective layer into the metal results in an extra durable gradient coating with positive pressing stress forming along the entire treated surface in the final stage of Revitalization. Application: Ensure the syringe is at room temperature so that contents flow freely. Add the necessary amount of the revitalizant into the transmission fluid reservoir. Drive the car normally. Revitalization is considered to be complete after 50 hours (approx. 1,500 km or 950 miles) of transmission operation. Dosage: 5-8 ATF qts = 1 Syringe 9-12 ATF qts = 2 Syringes 13-15 ATF qts = 3 Syringes Note: A decrease in noise levels from the very first hour of operation is a sign that the revitalization process has begun. Some automobiles with excessive transmission wear may require an extra dose of EX120, especially when improvement is noticed, but soon after problems return. Revitalizant is compatible with all types of fluids for the automatic transmissions: Dexron, Mercon, Mopar, CVT, etc. It does not enter into chemical reactions with transmission fluids or change their viscosity, friction or other physical-chemical properties. The protective metal-ceramic coating is formed on any operative mechanism, however, if the state of the mechanism (part) is in critical condition (100% wear), the worn part should be replaced.10.
