Abstract

The instant invention relates to a thermally stable, friction, wear and degradation reducing transmission fluids for use in highly stressed power transmission systems. The transmission fluids of the instant invention have improved performance under extreme conditions and extend the life of automatic transmissions.

Claims

exact text as granted — not AI-modified
1 . An automatic transmission fluid having improved performance and durability.  
   
   
       2 . The automatic transmission fluid of  claim 1 , wherein the automatic transmission fluid comprises 1-4% viscosity index improver.  
   
   
       3 . The automatic transmission fluid of  claim 1 , wherein the automatic transmission fluid comprises 0.01-1.5% corrosion inhibitor.  
   
   
       4 . The automatic transmission fluid of  claim 1 , wherein the automatic transmission fluid comprises 0.01-1.5% oxidation inhibitor.  
   
   
       5 . The automatic transmission fluid of  claim 1 , wherein the automatic transmission fluid comprises 0.01-5.0% dispersants.  
   
   
       6 . The automatic transmission fluid of  claim 1 , wherein the automatic transmission fluid comprises 0.1-17% lubricating oil.  
   
   
       7 . The automatic transmission fluid of  claim 1 , wherein the automatic transmission fluid comprises neopolyol ester.  
   
   
       8 . The automatic transmission fluid of  claim 1 , wherein the automatic transmission fluid comprises 0.01-1.5% lubricating oil flow improver.  
   
   
       9 . An automatic transmission fluid comprising a polyol ester, a friction modifier, a viscosity index improver, a corrosion inhibitor, an antioxidant, dispersants, a lubricating oil flow improver, anti-foam agents, and anti-wear additives.  
   
   
       10 . The automatic transmission fluid of  claim 9 , wherein the viscosity index improver is in a concentration of 1.0-40%.  
   
   
       11 . The automatic transmission fluid of  claim 9 , wherein the friction modifier is in a concentration of 0.01-1.5%.  
   
   
       12 . The automatic transmission fluid of  claim 9 , wherein the corrosion inhibitor is in a concentration of 0.01-1.5%.  
   
   
       13 . The automatic transmission fluid of  claim 9 , wherein the anti-wear additives are in a concentration of 0.001-0.01%.  
   
   
       14 . The automatic transmission fluid of  claim 9 , wherein the anti-foam agent is in a concentration of 0.001-0.01%.  
   
   
       15 . The automatic transmission fluid of  claim 9 , wherein the dispersants are in a concentration of 0.01-5.0%.
