ACDelco Automatic Transmission Conditioner

ACDelco Automatic Transmission Conditioner is a lubricant that is added to the transmission fluid. It conditions the transmission seals, aids in extending the life of the transmission, and improves shifting.


  • Conditions transmission seals
  • Extends the life of transmission and transmission fluid
  • Helps improve shifting


  • 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 kilometers driven since last fluid change exceed recommended limit.


  • 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 range from 64,000 to 96,000 kilometers depending on the severity of the usage. See your owner’s manual.
  • 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 already occurred.


Q: Does my transmission fluid need to be changed as regularly as my oil?
A: 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.

Q: Are there common causes of transmission fluid contamination?
A: Yes. Contaminants most often come from metal filings or ‘burnt’ byproducts from extreme usage or fluid degradation over time.

Q: Are there preventative steps I can take to minimize contamination?
A: Yes. Inspect the fluid using the dip stick at every oil change to determine if degradation or contamination is occurring.

Q: Can I identify which transmission fluid(s) are applicable/appropriate for my vehicle?
A: Yes. Refer to your vehicle owner’s manual for the specific fluid for your vehicle.
