There are a lot of different transmission fluids on the market these days, and it can be hard to figure out which one is the best for your car. If you’re looking for a quality DEXRON II transmission fluid equivalent, then you should definitely check out ACDelco or Mobil 1. ACDelco is a well-known brand that makes high-quality products, and their DEXRON ATF is no exception.
DEXRON II Equivalent
ACDelco Dexron VI Full Synthetic ATF is backward compatible with previous Dexron fluids and can replace older vehicles/transmissions. It outperforms previous Dexron fluids in friction durability, viscosity stability, aeration and foam control, and oxidation resistance – meaning you could see improved fuel economy and longer transmission life. Plus, its synthetic formulation allows for extended drain intervals, making maintenance easier on you.
Mobil 1 Synthetic LV ATF HP is an advanced full synthetic automatic transmission fluid that is specially designed to extend your transmission’s life. The high-performance formula protects your automatic transmission in all conditions and is formulated from synthetic base oils and an advanced additive system. This fluid provides maximum protection and performance for your transmission and is the perfect choice for those who demand the best for their vehicle.
On October 1, 2018, a new fluid requirement (GMNA-9986555) was published for the “Dexron Approved” Mobil 1 Synthetic LV ATF HP. This updated fluid was first presented in GM Technical Service Bulletin 18-NA-355 in December 2018. The change is to aid in eliminating torque converter clutch shudders in the GM 8L90 and 8L45 automatic transmissions after a complete system flush. [source]
Can You Use DEXRON VI Instead Of DEXRON II?
Yes, you can use DEXRON VI instead of DEXRON II, but it’s important to make sure that your car can handle the change. There should be no issues with ACDelco and Mobil 1 ATF. They are backward compatible with previous Dexron automatic transmission fluids and can be used as a much-improved substitute for older cars/transmissions that previously relied on Dexron fluid.
What Happens If I Use The Wrong Transmission Fluid?
The wrong transmission fluid can lead to increased wear and tear over time, which can sometimes shorten the lifespan of your car’s automatic transmission. It can also cause transmission fluid leaks, so it’s important to be sure that you’re using the correct type of fluid for your car.
Is DEXRON 2 Still Available?
These are the original GM Dexron ATFs, which have been discontinued by the firm and replaced with Dexron III, which has now been superseded by Dexon VI.
The GMNA-9986555 is a new required fluid for the “Dexron Approved” Mobil 1 Synthetic LV ATF HP.
