Are automatic transmission fluids interchangeable?

Over the years, the various formulations of Dexron and Mercon were adopted by a number of other auto manufacturers as the specification for their automatic transmissions, as well. Moreover, because Dexron and Mercon were very similar, these fluids themselves came to be regarded as interchangeable.

Can I use any automatic transmission fluid?

Each car has its own recommendations from the manufacturer on which transmission fluid your car needs. Some transmission fluids are very incompatible with different transmission types as they use different additives in the fluids.

What happens if you put the wrong transmission fluid in your transmission?

Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.

What type of automatic transmission fluid should I use?

Dexron III/Mercon – This is one of the most common fluids on the market. Most GM and Ford units call for this type of ATF, as well as many imports. If your owners manual recommends any form of Dexron, or any Mercon – other than Mercon V – this is the fluid you want.

Can you mix ATF 4 and Dexron?

Use ATF+4 only. Don’t use anything with Dexron/Mercon fluids. These fluids will cause TCC slippage/chatter problems plus wear out your transmission sooner than you would like for. The slipping could also be due to the bands needing adjustment.

Can you mix old and new transmission fluid?

This fluid starts to lose its standard properties and should be changed to keep the transmission parts and its performance at its peak. Mixing old and news fluids wont give you the ideal viscosity and the reduces the performance of the transmission system.

Is dexron 3 the same as ATF 4?

Dexron IV was an upgraded version of Dexron III, which was used by GM only briefly. … GM considers Dexron VI to be “backward compatible,” meaning GM recommends it for use in any vehicle that originally used any earlier version of Dexron and that it can be mixed with them.

Is synthetic transmission fluid better than regular transmission fluid?

A synthetic fluid has the capability of providing your transmission with a smoother operation. Because of superior engineering, the synthetic fluid is better at lubricating your transmission and is able to sustain its viscosity in a broad temperature range. … This will likely be true even with variations in temperatures.

What are the symptoms of low transmission fluid?

Symptoms of Low Transmission Fluid

  • Drips or puddles underneath the car.
  • Difficulty shifting through gears and/or slipping.
  • Shuddering or shaking.
  • Lurching or sudden jerks.
  • Transmission won’t engage.
  • Humming or clunking noises.
  • A burning smell.

Is it bad to add transmission fluid?

Pull out the transmission fluid dipstick. Wipe the dipstick on a clean rag or paper towel, reinsert it and pull it out again to check the transmission fluid level. The fluid level should be between two marks labeled either “Full” and “Add” or “Hot” and “Cold.” Usually, you should not have to add transmission fluid.

What does ATF 4 mean?

ATF +4 is a synthetic fluid for finely-tuned transmissions, so if you use a non-synthetic ATF instead of ATF +4 in a car or truck that calls for it, you could damage the transmission. You may use ATF +4 in most applications that call for older Dexron and Mercon fluids.

Can you mix different transmission fluids?

Is it OK to mix synthetic ATF with a conventional and/or synthetic blend ATF? Yes. Synthetic ATF and conventional fluids are 100 percent compatible with each other.
