TRIAX ATF 689 Full Synthetic

Trying a new Thing

I must say TRIAX provide an awesome delivery service, package came very quickly and well packaged. My 18 RAM with over 113k miles needed to have its transmission serviced, a thing that the dealership doesn't do, because the manufacturer claims the fluid is lifetime. I decided to do it myself, while researching and comparing fluids, I like the spec's on the TRIAX 689. It pretty much mirrors the ZF Lifeguard 8 / MOPAR 8&9 speed ATF. This was the first I've ever heard of TRIAX, based on the specs and others reviews I decided to chance it and give it a try. They end result was Worth taking the risk, my truck's transmission operated flawlessly immediately, it shifted super smooth, with crisp responses. I've logged over 1k miles since servicing and I sold on this product, it's my default choice going forward. Based on the TRIAX 689 specs and price point and performance it's definitely a no brainer.

Good stuff

This fluid did seem to repair an issue with an 8HP in a grand cherokee that would not stay out of park in very cold weather. Transmission did have max life in it. serviced with Triax 689 and it has been problem free.

No comebacks

Customers have called back to say how much better their ZF trans is shifting after replacing fluid with TRIAX 689
