ACDelco GM Original Equipment 10-9395 Dexron VI Automatic Transmission Fluid
Secondly, I’ve another great product, “ACDelco GM 10-9395 Dexron VI ATF”. For Tranny fluid 7004, Dexron III was a popularly used ATF which was replaced by Dexron VI. So this one and the previous product are quite perfect.
In terms of friction durability and viscosity stability, the “ACDelco Transmission Fluid” is a great choice. This ATF also possesses aeration and foam control with oxidation resistance. Making the 700R4 work longer than average.
This also provides for extended drain intervals. Giving your transmission consistent shift performance, even in extreme situations. This fluid is eco-friendly and proved to be full-synthetic.
The only backlash is the quantity in a bottle of fluid is very low. Also, there are no definite brands of compatible transmissions that are not listed on the label.
But be careful! “ACDelco Dexron-VI Fluid” is not suitable for DCT (Dual Clutch Transmissions) or CVT (Continuously Variable Transmissions).
Our third product Castrol 03520C Transmax Dex/Merc Automatic Transmission Fluid is a popular one among users. This ATF meets Dexron-III H, Dexron-III, IIE and II.
Castrol Transmax Transmission Fluid is mostly used for transmissions and power steering of older versions of general motors and Ford vehicles. It’s also used in vehicles requiring Dexron and macron transmissions fluids.
This Trans Fluid has enhanced friction durability. Here, it will not only sustain the longevity but will also give smooth transmission performance.
Its superior high-temperature protection is best suited for both highway and city driving. The unsurpassed oxidation resistance helps your transmission to prevent excessive viscosity.
Make sure to check the vehicle’s user’s manual to ensure compatibility. One of the backlashes of this product is the labeling is confusing. The right compatible automobiles aren’t listed.
Also, another drawback is there are no guidelines if you can mix the non-synthetic fluid with it.
Chevy Blazer, Camaro, Impala, Corvette, Suburban, and even Oldsmobile Cars have this transmission. The list of cars containing a 700R4 is huge as most cars made from 1983 to 1991 have it.
So nonetheless, this transmission is quite popular. But choosing a Tranny fluid 700R4 is a very delicate job. If you choose the wrong one your transmission might face transmission failure.
So you have to keep some factors in mind. Here are some points I recommend you consider while choosing Tranny Fluid.
Most of the fluid in the market claims to be backward compatible. As 700R4 is made between the 80s-90s, most old vehicles have this transmission.
700R4 transmission is compatible with Dexron III fluid. But after the Dexron VI came out, most 700R4 transmissions are using Dexron VI. Some dual-compatible fluids are also used in these types of vehicles.
Most synthetic fluids are compatible with 700R4. If necessary you can mix other non-synthetic fluids in your transmission. Although it will be better if you don’t.
Synthetic Vs Non-Synthetic
In the fluid market, synthetic transmission fluids are more in demand than non-synthetic. Synthetic fluid is way more economical and sustainable than non-synthetic.
Here, the synthetic fluid gives you longer transmission life with reduced cost. It makes your maintenance less time-keeping. The synthetic fluid keeps moisture and chemicals away from transmission cases. So you get a rust-free transmission.
Synthetic fluid also gives your vehicle a smoother shift. Its resistance to oxidation helps sustain your fluid. Thermal degradation helps the transmission work at a lower temperature.
Even though some people prefer non-synthetic fluid as per tradition, synthetics are highly recommended.
Another type of fluid is multi-vehicle fluid. These types of fluids are best for backward-compatible transmission. There are some fluids in the market compatible with both Dexron and macron. You can buy them for use in multiple vehicles.
What Trans Fluid is Recommended for 700R4 Transmission
The listed four fluids are compatible with 700R4 transmission. All of them have the potential to give your transmission longevity. But to give you a thorough comparison I’ll acknowledge the main benefits of individual fluids.
Most cars with 700R4 transmissions are expensive vintage cars. They mostly use Dexron III’s upgraded version of Dexron VI. Dexron is backward compatible. So it is suitable for most old car models.
In our list ACDelco, Valvoline and Castrol are Dexron VI fluids. Among them, Valvoline and Castrol have dual-compatible fluids. It is backward compatible with both Dexron VI and Marcon. So you can use these with multiple vehicles.
Mobil 1 has the most temperature degradation allowing it to be used under rough winter weather. In terms of affordability, Castrol is both cheap and durable. All of the recommended fluid is synthetic which is great for your transmission.
With that being said, your choice and comfort are all that matters in the end.
How And When to Change 700R4 Transmission Fluid?
700R4 transmission fluid change is recommended frequently. The average fluid interval for manual transformation should be 30,000 to 60,000 miles. And for automatic transmission 60000 to 100000 miles will be fine.
First, you have to make sure your transmission is 700R4. If you can see 16 bolts on your transfer casket, then it is 700R4 or 4L60. If the transmission uses a TV cable as a speedometer, that’s a 700R4.
You will know by the color of the transmission fluid if it needs to be replaced. If the color is red, the ATF is good. But if it turns brown, it means the fluid is worn out. And if it turns dark brown or black, you better change the fluid ASAP.
Another sign of your fluid needing to be changed is if your vehicle makes a roaring or whining sound. Also, the rumbling and chattering after accelerating your vehicle can indicate fluid damage.
To change the fluid you first have to drain most of the old fluid out of the transmission through a filler tube. A hand-operated vacuum tube might do the job well.
After draining, fill the fresh fluid. Make sure to almost reach the 700R4 transmission fluid capacity. The previous remains will be diluted by the new ones. It is recommended to keep the clutch plates cool and primary chain lubed.
How much transmission fluid does a 700r4 hold?
700R4 holds about 11 quarts of fluid. It is recommended to put 6 quarts at first in the transmission and run it for 10 seconds. Then put another 5 quarts of Tranny fluid and run the transmission again.
Is it OK to overfill transmission fluid?
No. Overfilling a transmission can lead to hard shifting and slippage. The lubricating properties can also be lost if overfilled. In worst case scenario, the entire system can blow up and transmission will stop functioning.
Can you mix transmission fluid brands?
Yes, although it’s best if you read the fluid’s label. Most synthetics are 100% mixable with any conventional fluid. But keep in mind that mixing transmission fluid can disrupt your natural transmission life. So, it is not recommended.
I can understand the frustration a vehicle owner goes through while choosing the best transmission fluid for 700R4.
Our researchers and writers have tried their best to find the most suitable fluid. I’ve given all the benefits and comparisons. The details are carefully put for your convenience.
