GM Dex III doesnt exist anymore, your transmission prefers dex III over VI.

What? Our trannys prefer Dex III? Since when? I have been running Dex VI and I wouldn't ever switch back. Dex VI runs cooler, has much better properties.

For me, I run Valvoline synthetic Dex VI. But anything that is Dex VI should be fine.

I think he reversed the two on accident.

No, he didn't.

Dex III was recommmend by Trannyman95, who is the resident expert on transmissions and owns Triple Edge Performance - Home Page

I run a blend of DexVI and Transsend in the blue car. The silver car is getting DexVI...I also think it is still a better blend to run and is more easily available.

If your going to do anything...buy a shift kit when you do the pan drop. Your transmission will thank you. Quicker shifts = less clutch/band wear.

I know Dave and have spoke with him a couple times about tranny fluid. The fluid that he puts in all the transmission he installs is a mix. But you are correct it was a mix of Dex III. I believe he choose the mix he did because of its ability to stick to the differential. The newer Dex VI fluid is thinner and will not stick to the diff as well during burnouts.

So the way I took it when he described it to me, unless you are doing a lot of burnouts and racing at the track, Dex VI is a better fluid to use. If you are doing racings and pit burnouts, then his recommended Dex III mix is a better choice.

But to say that our transmissions prefer Dexron III fluid is a quite misguided.
