Perfect for a Toyota Transmission Flush
I picked up this 3-pack for a full transmission flush on my Toyota, and it was exactly what I needed. The fluid works really well, and you can tell it’s high-quality stuff. Buying it in the gallon 3-pack is definitely the way to go if you're doing a complete flush rather than just a simple drain and fill it gives you plenty of fluid to get the job done right without running back to the store. My car is shifting smoothly, and the price for the bundle is hard to beat. If you’re a DIYer looking to maintain your Toyota, this is a solid choice!

Castrol is a quality product
As pictured. Usually use a different brand but this did do the job on an old Honda so going to try it in my new pick up.

Cheap but quality transmission fluid for CVT transmission
The transmission fluid itself is some pretty pristine stuff, has everything a cvt transmission needs to make it run smooth. I got the 3 pack, which makes it easier on the wallet for when you need bulk, plus for a normal car, you have a gallon or so left over for any errors that may come along. Transmax offers transmission fluid that is cheaper than most competitors with the same quality as others. This stuff works great and doesn’t break the bank. Highly recommend

Perfect choice
Great product. You basically get 2 quarts free when compared to Valvoline or Mitsubishi fluid, you just have to flush the transmission if switching from the others so the first change is the OE price, then half the cost
