ACDelco ATF TYPE III-H

Transmission Fluid: ATF Type III-H | ACDelco

ACDelco ATF Type III (H) is a premium quality automatic transmission fluid for use in a variety of passenger cars and light trucks. It is formulated with select base oils and additives to meet the heavy demands placed on automatic transmissions, including the generation of electronically controlled transmissions. ACDelco ATF Type III (H) is recommended for the following uses: when DEXRON-III(H), DEXRON-III(G), DEXRON-II(E), DEXRON-II or Type A Fluids are required in all automatic transmissions built by GM that do not require DEXRON-VI and can used in some hydraulic and compressor systems where excellent low-temperature flow ability is required.

FEATURES & BENEFITS

  • Good frictional characteristics and wear protection provide enhanced cold-temperature performance, excellent friction retention and smooth shifting.
  • High oxidation resistance fortifies against rust and corrosion and provides for longer fluid change intervals.
  • Wide range of seal compatibility – can be used in an extensive variety of vehicles/transmissions.
  • Meets requirements for foam protection and protects against metal-to-metal friction and wear within the transmission.
  • 32 oz. Part No. 10-9047 88863083
     

 
Signs of Wear & Troubleshooting:

  • Causes of transmission fluid degradation include overall thermal stress, mechanical shearing and contamination.
  • Mechanical shearing affects the fluid’s viscosity modifiers, causing the fluid to thin.
  • Common sources of contamination include metals and other engine fluids.
  • Coolant contamination is particularly harmful and usually requires a complete overhaul or even replacement of the transmission.
  • Signs that transmission fluid should be replaced include transmission grinding or making strange noises, problems shifting gears, gears slipping, vehicle “surging” (lurching forward or falling back), delays in vehicle movement and/or miles driven since last fluid change exceed recommended limit.
     

Good Maintenance Practices:

  • Transmission fluid should be replaced when it becomes contaminated.
  • Anything but transmission fluid in the transmission is considered a contaminant.
  • Always use the recommended type of transmission fluid in your vehicle, as referred to in your Owner’s Manual.
  • Typical fluid change intervals for automatic transmissions vary depending on the severity of the usage. See your Owner’s Manual for maintenance schedules.
  • In addition to fluid replacement, it is important to regularly check your transmission fluid level.
  • A low transmission fluid level can cause the vehicle to shift improperly or not at all.
  • Stay vigilant – warning signs of low transmission fluid may not appear until serious damage has occurred.
     

FAQs:

Can ATF Type III (H) be used in a non-GM vehicle?

  • Yes, ATF Type III (H) can be used in any vehicle that can use DEXRON-II or DEXRON-III fluid.

 

My current transmission fluid is not on the above list – can I determine if ATF Type III (H) is a suitable ATF replacement for my vehicle?

  • Yes, ATF Type III (H) can be used in any vehicle that can use DEXRON-II or DEXRON-III fluid. Refer to your Owner’s Manual for the specific transmission fluid required by your vehicle.

 

Can DEXRON-VI be used as a substitute for ATF Type III (H)?

  • Yes, DEXRON-VI is a suitable replacement.

 

Does my transmission fluid need to be changed as regularly as my oil?

  • No, transmission fluid is designed to last much longer than most engine oils. Always refer to your vehicle Owner’s Manual to identify how often and when your transmission fluid should be changed. Severe usage and regular usage descriptions are provided.

 

Are there common causes of transmission fluid contamination?

  • Yes, contaminants most often come from metal filings or “burnt” byproducts from extreme usage or fluid degradation over time.

 

Are there preventative steps I can take to minimize contamination?

  • Yes, inspect the fluid using the dipstick at every oil change to determine if degradation or contamination is occurring.

 

Can I identify which transmission fluid(s) are applicable/appropriate for my vehicle?

  • Yes, refer to your vehicle Owner’s Manual for the specific fluid for your vehicle.
